Cystic Echinococcosis (CE) is a rare but serious parasitic disease caused by Echinococcus granulosus sensu lato, representing only 1–2% of all hydatid disease cases. Due to its nonspecific clinical presentation, its diagnosis and management pose significant challenges. This study aimed to provide a comprehensive overview of intracranial CE cases reported globally over the past 35 years, focusing on demographic characteristics, clinical presentation, diagnostic approaches, treatment modalities, and outcomes. Methods: A systematic review was conducted in accordance with PRISMA guidelines and was registered in PROSPERO (CRD 42024608624). Relevant studies published between 1990 and 2024 were identified from PubMed, Scopus, and Web of Science databases. Results: After screening and eligibility assessment, 392 studies involving 718 intracranial CE cases were included. The majority of patients were children (65%) and male (59.2%). The most frequent presenting symptoms were signs of increased intracranial pressure (79.4%), followed by motor deficits (37.9%) and visual disturbances (23.2%). Most cysts were located in the supratentorial region (88.9%), predominantly in the parietal lobe, and were solitary (88.4%). Surgical intervention was performed in 95.8% of cases, often combined with albendazole therapy. Complete recovery was observed in 85.5% of patients, while 8.7% died—primarily due to cyst rupture-related complications such as septicemia and anaphylaxis. Recurrence was reported in 26% of cases with follow-up. Conclusions: This review presents one of the most extensive analyses of intracranial CE to date. Despite being a rare manifestation, intracranial CE should be considered in the differential diagnosis of space-occupying brain lesions in endemic areas, particularly in paediatric patients.

Background: Hydatid disease, caused by the larval form of Echinococcus granulosus, is a rare but potentially life-threatening condition during pregnancy, with an estimated incidence of 1 in 20,000 to 30,000 gestations. Physiological immunosuppression and increased placental steroid levels during pregnancy may promote cyst growth, elevating the risk of rupture, which can result in anaphylactic shock, sepsis, or widespread peritoneal dissemination. Diagnostic imaging, particularly ultrasonography, plays a central role in detection, while treatment decisions are complicated by the lack of standardized guidelines and the need to balance maternal–fetal safety. Methods: This case report describes a 29-year-old pregnant woman at 22 weeks’ gestation who was incidentally diagnosed with two large hepatic hydatid cysts during a routine ultrasound. Results: Given the high rupture risk, she underwent successful laparoscopic surgery in the second trimester, followed by careful monitoring and elective cesarean delivery at term. A third retroperitoneal cyst, initially managed conservatively, was excised postpartum. Conclusions: This case highlights the critical importance of individualized, multidisciplinary management in achieving favorable maternal and neonatal outcomes in complex presentations of hydatid disease during pregnancy.

Background and Clinical Significance: Cystic echinococcosis (CE), also known as hydatid disease, is a zoonosis in whose life cycle humans can be an accidental intermediate host. The liver is the most commonly affected organ, with complications like cyst rupture, hematogenous spread, and infection. Imaging techniques, such as ultrasound, CT, and MRI scans, play a vital role in diagnosing and classifying the disease, facilitating the appropriate therapeutic approach. Treatment options include albendazole for early stage cysts, with more invasive procedures like PAIR, MoCAT, and surgery for advanced cases. This article highlights the importance of imaging modalities in the diagnosis and therapeutic management of CE. Case Presentation: We report a case of a 23-year-old female patient presenting with nausea, fatigue, and loss of appetite to the emergency department, who was diagnosed with a giant echinococcosis lesion. The patient received ultrasound, MR, and CT diagnostics initially. The surveillance included ultrasound and MRI, as well as an anthelmintic therapy, and eventually led to an open resection. Conclusions: This case highlights the importance of imaging modalities in diagnosing and therapeutically managing CE. It explains the key features of each WHO classification stage of the disease for each modality, emphasizing the value of an MRI scan as a possibility for surveillance and a bridge to surgery.

Background and Objectives: The aim of this study was to evaluate the clinical presentation, treatment outcomes, and complications associated with hepatic hydatid cysts in a pediatric population. Materials and Methods: This retrospective study analyzed 214 pediatric patients with liver hydatid cysts, focusing on clinical presentation, treatment outcomes, and associated complications. Patients were classified based on treatment modality, including non-operative management with albendazole, PAIR, and surgical intervention. This study compared cyst characteristics, recurrence rates, and complications such as cysto-biliary fistulas. Results: Among the patients, 68% (n = 145) had a single cyst and 86% (n = 184) were found to have isolated liver cysts. No significant statistical difference was observed between Group 1 and Group 2 in terms of age, gender, and basic laboratory values and general characteristics of the cysts, such as the lobe where the cyst was located, involvement of multiple organs, number of cysts, the state of cyst rupture, and recurrence; no statistically significant difference was found between the groups (p > 0.05 for each comparison). Cyst rupture incidence was 6%, and the average incidence of recurrence was 2%, with a surgical recurrence incidence of 3%. A total of 37 patients had a laparotomy, while 7 had laparoscopic surgery. In total, capitonnage was performed in 68 patients, omentopexy in 4, and cystostomy in 6. Consequently, among the treated patients (PAIR + surgery), the incidence of cysto-biliary fistula was 11%, anaphylaxis was 2%, surgical recurrence was 3%, and the incidence of reoperation (Clavien–Dindo ≥ 3) was 6%. The average follow-up period was 72 months, during which no mortality was observed. Conclusions: We identified key clinical outcomes related to both non-surgical treatments (cyst rupture and recurrence) and surgical groups (cysto-biliary fistulas, anaphylaxis, the need for reoperation, rupture, and recurrence).

Hepatic hydatid cysts are an example of a zoonosis with global distribution, but with endemic characteristics in certain geographic areas. Known since ancient times, this parasitic infection predominantly affecting the liver and lungs remains a challenge today in terms of diagnosis and the pharmacological, radiological, endoscopic, or surgical therapy. This study analyzed the complications associated with different procedures for treating hydatid cysts in 76 patients admitted to the County Clinical Emergency Hospital of Sibiu. Complications occurred in 18 patients (23.7%), with no significant correlation to age, gender, or residency (urban or rural). Patients undergoing open surgery exhibited the highest complication rate (61.1%) compared to those treated with other procedures. The most frequent complication was biliary duct rupture, occurring in 22.7% of cases. Our findings indicate that the presence of complications significantly prolongs hospitalization time [t df (75) = 12.14, p < 0.001]. Based on these findings, we conclude that the surgical approach for hydatid cysts should be meticulously tailored to each patient’s specific circumstances to reduce the risk of complications and improve clinical outcomes.

Cystic echinococcosis is a zoonotic parasitic disease that affects the liver in more than 70% of cases, and there is still an underestimated incidence in endemic areas. With a peculiar clinical presentation that ranges from paucisymptomatic illness to severe and possibly fatal complications, quality imaging and serological studies are required for diagnosis. The mainstay of treatment to date is surgery combined with antiparasitic agents. The surgical armamentarium consists of open and laparoscopic procedures for selected cases with growing confidence in parenchyma-sparing interventions. Endoscopic retrograde cholangiopancreatography (ERCP) is extremely useful for the diagnosis and treatment of biliary fistulas. Recent relevant studies in the literature are reviewed, and two complex cases are presented. The first patient underwent open surgery to treat 11 liver cysts, and during the follow-up, a right pulmonary cyst was diagnosed that was treated by minimally invasive surgery. The second case is represented by the peritoneal rupture of a giant liver cyst in a young woman who underwent laparoscopic surgery. Both patients developed biliary fistulas that were managed by ERCP. Both patients exhibited a non-specific clinical presentation and underwent several surgical procedures combined with antiparasitic agents, highlighting the necessity of customized treatment in order to decrease complications and successfully cure the disease.

Purpose: Cystic echinococcosis (CE) is a common, complex parasitic disease that constitutes a major public health concern. CE demonstrates high endemicity in areas where dogs are used for herding or where animal husbandry practices involve close contact with livestock. It can clinically manifest with a variety of signs and symptoms, such as cholangitis, jaundice, pancreatitis, external biliary fistula, inferior vena cava obstruction, portal hypertension, and superinfection. The latter can notably be related to suppuration, either by rupture or bacteremia. The aim of this study is to report our 76-year-old patient who presented with a primarily infected giant-suppurated hydatid cyst of the liver and its surgical management. Methods: In this case, the diagnosis was based primarily on clinical presentation, computed tomography (CT) scan, and magnetic resonance imaging (MRI) of the patient’s abdomen. The surgical procedure of choice was the partial retaining of the pericystic membrane and drainage of the cystic contents (partial pericystectomy). Results: The surgical management and meticulous long-term follow-up of our patient produced a positive outcome without any post-operative complications. Full article

(1) Background: Hydatidosis, or human cystic echinococcosis, is a zoonotic disease. Endemic in some areas, recently it has an increasing incidence in wider regions, determined by population migration. Clinical features depend on the localization and level of infection: asymptomatic or with signs related to hypersensitivity, organic functional deficiencies, expanding mass effects, cyst infection and sudden death. In rare cases, the rupture of a hydatid cyst causes emboli formation by the residual laminated membrane. (2) Methods: We performed an extensive literature review, starting from the case of a 25-year-old patient presenting with neurologic symptoms relevant for acute stroke, associating right upper limb ischemia. (3) Results: Imaging investigations revealed the source of the emboli as the rupture of a hydatid cyst, the patient presenting multiple pericardial and mediastinal localizations. Cerebral imaging confirmed an acute left occipital ischemic lesion, with complete recovery of the neurological deficit after therapy, while surgery for acute brachial artery ischemia had a favorable postoperative evolution. Specific anthelmintic therapy was initiated. An extensive literature review using available databases revealed the scarcity of data on embolism as a consequence of cyst rupture, highlighting the significant risk of clinicians overlooking this possible etiology. (4) Conclusions: An associated allergic reaction should raise the hypothesis of a hydatid cyst rupture as a cause of any level acute ischemic lesion. Full article

Central nervous system (CNS) cystic echinococcosis (CE) is a rare disease caused by Echinococcus which especially exists in agricultural endemic areas. This condition is more frequent in the pediatric and adolescent population and it can be associated with hydatid cyst in other localizations. A literature search was conducted up to 28 April 2021 by two independent reviewers. This study focused on clinical, imaging, therapeutic features as well as on complications of CNS CE among children and adults. Fifteen studies from seven different countries were included. A significant prevalence in males (ranging from 51% to 100%) was observed with an average rate of 60%. CNS CE was mainly single and located in the parietal region. The predominant symptoms were those of increased intracranial pressure. All patients were treated surgically, and the most common post-surgical complication was cyst rupture (prevalence: [3.3–37.5%], average: 12.9%). Furthermore, the outcomes were worse amongst patients with cyst ruptures and multiple recurrences. The average proportion of deaths due to CNS CE was 5.6% (range: 2.5–14.8%). This review highlights the necessity of including CNS CE in the differential diagnosis of patients with cystic lesions, especially in those residing in endemic areas. Early gross total cyst removal is the mainstay of treatment yielding the best outcomes. Full article

A 23-year-old woman was presented to the Emergency Unit with intracranial hypertension syndrome and blindness in her left eye which had started recently. A cranial native computed tomography scan and a magnetic resonance imaging (MRI) with contrast examinations revealed a giant intracranial cystic lesion, extending into the left frontal lobe, which was compressing the optic chiasm and eroding the internal plate of the left frontal bone. Surgical craniotomy was performed for evacuation and decompression, but during the craniotomy the cyst ruptured. After assessing the degree of erosion of the internal bone plate, we concluded that the primary origin of the cyst was intraosseous. With the dura mater being intact, abundant lavage with H₂O₂ was applied and the bone flap was replaced after rigorous bone scraping. Imaging control at six and twelve months identified no recurrence of the cyst. In the literature, hydatid cysts located in the skull bone are very rare and most of them rupture intraoperatively. Given their extremely low incidence in developed countries, any neurosurgeons’ experience with such pathology is limited and in some cases surgery cannot be delayed. In the case of intracerebral hydatid cysts, a neurosurgeon usually has only one shot at surgery, so simple and quick-to-access therapeutic guidelines must be developed in order to inform the choice of surgical technique. We conclude that the most successful surgical approach could be double concentric craniotomy. This surgical technique is used in intracerebral tumors, which also have an important bone invasion.

Background and Objectives: Hydatid disease (HD) remains a significant public health issue causing morbidity and mortality in many Mediterranean countries. Material and Methods: The present cohort study included 50 consecutive patients with liver hydatid disease who underwent surgery in a tertiary University Hospital. A total of 18 patients (36%) had a case of complicated HD, including simple communication of the cyst with the biliary tree (6 cases), rupture of the cyst into the biliary tree (6 cases), presence of a bronco-biliary fistula (2 cases), rupture of the cyst in the peritoneal cavity (2 cases), and rupture of the cyst and formation of a hepatic abscess (2 cases). Endoscopic retrograde cholangiopancreatography (ERCP) was pre-operatively performed on six patients. Results: The main clinical symptom presented was right upper quadrant pain in 16 patients (88%), which was associated with high fever (>39 °C) in 14 patients (78%). C-reactive protein (CRP) was the primary indicator of a complicated HD (p = 0.003); however, it was only elevated in 67% of cases. CRP was a more sensitive indicator of a rupture in the biliary tree cyst (p = 0.02). Computer tomography (CT) detected more cases (44%) of a complicated HD than ultrasonography (US) (25%); however, the difference was not statistically significant. Conclusions: For prevention and control of HD, a high suspicion of the disease leading to early referral to specialized centers, mainly in endemic areas, is required. Prior to surgical or percutaneous intervention, a combination of imaging and laboratory findings are essential in diagnosing a complicated case and avoiding unnecessary interventions. Full article
