BACKGROUND: Hydatidosis is an anthropozoonosis due to the development in humans of the larval form of Echinococcus granulosus and is endemic in many countries of the Mediterranean region such as Morocco.
METHODS: We report three cases of hydatid cyst at unusual locations such as the peritoneum, and the retroperitoneum.
CONCLUSIONS: Hydatid disease usually involves the liver (75 %), the lungs (15.4 %), and the spleen (5.1 %). Almost any anatomic location can be the host site of the parasitic cysts.
CONCLUSIONS: Multiple locations of hydatid cyst often pose a problem of differential diagnosis. Surgery is the mainstay of treatment.

UNASSIGNED: Hydatid cysts (HC) are zoonotic diseases that are mainly caused by Echinococcus granulosus. Ovarian HC is a rare condition with different and unspecified presentations. Here we report a rare case of primary ovarian HC.
UNASSIGNED: A 47-year-old woman with chronic abdominal pain and left hemipelvic fullness was referred to the Obstetrics Clinic of the Kowsar Hospital of Qazvin. Abdominopelvic sonography revealed a cystic mass, which primarily suggested a cyst adenoma. The tumor marker levels were within normal limits. After surgical resection, histopathological examination showed a cystic mass with dimensions of 10×6×3 cm, smooth external and internal aspects, wall thickness of 0.3 cm, and multiple pieces of irregular gray membranous tissue. The patient was treated with albendazole 3 months after surgery, and a 6-month follow-up sonogram revealed no signs of recurrence.
UNASSIGNED: HC has non-specific presentations. Radiologists, pathologists, and surgeons should consider HC as a differential diagnosis for any cystic mass in the pelvic cavity, especially in endemic areas. Surgical resection and albendazole administration are the chosen treatments.
UNASSIGNED: Echinokokkuszysten (EZ) sind Zoonosen, die hauptsächlich durch Echinococcus granulosus verursacht werden. Echinokokkuszysten im Eierstock sind eine seltene Erkrankung mit unterschiedlichen, unspezifischen Präsentationen. In diesem Bericht stellen wir einen seltenen Fall einer primären Echinokokkuszyste im Eierstock vor.
UNASSIGNED: Eine 47-jährige Frau mit chronischen Bauchschmerzen und einer gefüllten linken Becken wurde in die Geburtsklinik des Kowsar-Krankenhauses in Qazvin überwiesen. Die abdominale Sonographie zeigte eine zystische Masse, die zunächst auf ein Zystadenom hindeutete. Die Tumormarkerwerte lagen aber im normalen Bereich. Nach chirurgischer Resektion zeigte die histopathologische Untersuchung eine zystische außen und innen glatte Masse mit Abmessungen von 10×6×3 cm, einer Wanddicke von 0,3 cm und mehreren Stücken unregelmäßigen grauen membranösen Gewebes. Die Patientin erhielt 3 Monate nach der Operation eine Behandlung mit Albendazol; die 6-monatige Nachuntersuchung per Ultraschall ergab keine Anzeichen für ein Rezidiv.
UNASSIGNED: Echinokokkuszysten zeigen unspezifische Symptome. Radiologen, Pathologen und Chirurgen sollten EZ als differenzialdiagnostische Möglichkeit für jede zystische Masse im Beckenraum in Betracht ziehen, insbesondere in endemischen Gebieten. Chirurgische Resektion und die Verabreichung von Albendazol sind die bevorzugten Behandlungen.

UNASSIGNED: In cystic lesions of the pancreas, hydatid cyst should be considered in the differential diagnoses and its presence should be ruled out before any invasive interventions. Serological tests along with imaging studies related to hydatid cyst diagnostic indicators should be performed in people who live in Echinococcus granulosus endemic areas and suffer from cystic lesions of the gastrointestinal tract.
UNASSIGNED: Primary pancreatic hydatid cysts, caused by the tapeworm Echinococcus granulosus, represent a rare occurrence often challenging to diagnose due to their similarity to other pancreatic conditions. This case report outlines a 67-year-old male presenting with jaundice and cholestasis but lacking typical symptoms associated with pancreatic hydatid cysts. Laboratory findings revealed elevated bilirubin levels, liver enzyme abnormalities, and tumor markers, prompting imaging studies that indicated a cystic mass near the pancreatic head. Misdiagnosed initially as a mucinous cystic neoplasm, the patient underwent Whipple surgery, unveiling a large cystic lesion upon examination.

Studies on alterations in inflammatory markers and risk factors for perforation in hydatid cysts of the lung are rare. In our study, we planned to investigate the effect of inflammatory markers on prognosis of hydatid cyst disease. 37 patients underwent surgery for pulmonary hydatid cyst between February 2022 and October 2023 and analyzed retrospectively. Inflammatory markers were calculated from preoperative and postoperative 3rd-month peripheral blood results. Cyst size was 58.5 ± 28.0 mm, 5 patients had bilateral cysts and 11 patients had multifocal cysts. Preoperative white blood cell, white blood cell difference, preoperative and postoperative eosinophils, preoperative neutrophils, neutrophils difference, preoperative systemic immune inflammatory index, systemic immune inflammatory index difference and preoperative eosinophil lymphocyte ratio were higher in patients with perforated cysts, the cut-off value for preoperative white blood cell for perforation was 10,535, preoperative cut-off value for eosinophils was 230, preoperative cut-off value for neutrophils was 8815, the cut-off value for preoperative systemic immune inflammatory index was 1129.83 and the cut-off value for preoperative eosinophil-lymphocyte ratio was 0.09. In patients with preoperative eosinophil, neutrophil, white blood cell, eosinophil-lymphocyte ratio and systemic immune inflammatory index values above the cut-off value, the probability of perforation increased 7.5, 13.6, 6.3, 9.6, and 9.3 times, respectively.

Tapeworms of the genus Echinococcus cause parasitic disease in humans through the ingestion of eggs in contaminated food and water. Rupture of slowly enlarging cysts in the liver, lungs, and other organs can be life-threatening and many deaths are recorded yearly worldwide. Surgery and removal of such cysts remain the most effective treatment. Veno-venous extracorporeal membrane oxygenation (ECMO) routinely placed in the ICU in patients with acute respiratory distress syndrome (ARDS), may provide time and adequate oxygenation for the completion of surgery in echinococcosis cases. In this article, we present a rare case of pulmonary echinococcosis in a young patient requiring ECMO support prior to surgery.

Primary intramuscular hydatid cysts are uncommon due to the contractile nature of muscles and their lactic acid content. Hydatid cysts with spinal extension are sometimes seen with primary vertebral body involvement. Our patient presented with a slow-growing posterior abdominal wall mass, and upon magnetic resonance imaging (MRI), it was revealed to be several cystic lesions in the abdomen wall with extension through the neural foramina into the spinal canal. The key differentials for spinal canal masses with neural foraminal expansion and muscle involvement are peripheral nerve sheath tumors. Our case report adds hydatid cysts to the differentials for well-defined cysts with variable intensities on MRI.

UNASSIGNED: This study aims to investigate whether the concept of doubling time in hydatid cysts differs according to different parameters such as age, sex, and whether the cyst is located in the lung or liver. Background: This study aims to investigate whether the concept of doubling time in hydatid cysts differs according to different parameters such as age, sex, and whether the cyst is located in the lung or liver.
UNASSIGNED: Between January 2012 and August 2023, a total of 138 hydatid cysts were retrospectively analyzed. There were 55 pulmonary (32 males, 23 females; mean age: 25.6±23.8 years; range, 2 to 77 years) and 83 hepatic hydatid cyst patients (32 males, 51 females; mean age: 31.1±22.8 years; range, 3 to 75 years).
UNASSIGNED: The mean doubling times for pulmonary and hepatic hydatid cysts were 73.4±41.8 and 172.6±108.8 days, respectively (p<0.001). When children (≤18 years old) and adult cases were compared for pulmonary hydatid cysts, the mean doubling times were 61.1±17.6 and 87.1±55.3 days, respectively (p=0.119), and for hepatic hydatid cysts, 110.6±48.4 and 215.6±118.3 days, respectively (p<0.001). While comparing male and female cases, the mean doubling time for pulmonary hydatid cysts was 77.6±32.2 and 67.6±52.6 days, respectively (p=0.018), while for hepatic hydatid cysts, it was 192.0±111.7 and 160.4±106.2 days, respectively (p=0.250).
UNASSIGNED: The doubling time seems to be approximately 10 weeks in the lung and approximately 25 weeks in the liver. Hydatid cysts grow faster in children than adults in both the lungs and liver.

Cystic echinococcosis (CE) is a zoonotic disease affecting humans and animals. Despite a lack of clarity about many details of parasite-intermediate host interactions, the nature of the immune responses triggered by hydatid infection has revealed new perspectives. This study discusses the latest advances in elucidating the immunologic mechanism of echinococcosis and its detection and potential approaches to enhance serodiagnosis accuracy. Moreover, nanobiosensors have been evaluated according to their potential to improve treatment efficiency and aid in an early diagnosis of cystic echinococcosis. The serum of an intermediate host can diagnose CE by analyzing antibodies induced by Echinococcus granulosus. Among the most notable features of this method are its noninvasive ability and high sensitivity, both of which make it an excellent tool for clinical diagnosis. Several serological tests, including ELISAs and immunoblotting, can detect these antibodies to assess the disease\'s state and determine the treatment outcome. A thorough understanding of what cross-reactivity means and the stage of the disease are crucial to interpreting serological results. Nanobiosensors have also proven better than conventional biosensors in detecting hydatid cysts. Additionally, they are highly sensitive and versatile when detecting specific biomarkers, improving diagnostic accuracy. These immunomodulatory molecules, induced by E. granulosus, are a good candidate for diagnosing cystic echinococcosis because they alter intermediate host immune responses. Hydatid cyst detection is also enhanced through nanobiosensors, which provide better accuracy.

Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

BACKGROUND: Echinococcosis, commonly known as hydatid disease, is a zoonotic infection resulting from the tapeworm Echinococcus granulosus. The occurrence of hydatid cysts in the orbital region is uncommon, representing less than 1% of all reported hydatid cases. This report details a unique case of an intramuscular hydatid cyst in the orbital region that led to compressive optic neuropathy.
METHODS: A 22-year-old male from Kabul, Afghanistan presented with a five-month history of progressive proptosis in his left eye, associated with a gradual decrease in vision over the past three weeks. The left eye exhibited upward globe dystopia, ocular motility limitation, mild conjunctival injection, and chemosis. Diagnosis was achieved through imaging and histopathological examination. Treatment involves surgical removal of the cyst and prolonged albendazole therapy. The postoperative course showed significant improvement in the patient\'s condition and restoration of his vision.
CONCLUSIONS: Despite its rarity, this case underscores the importance of awareness and knowledge of hydatid disease among physicians, especially those working in endemic areas. It emphasizes the importance of including hydatid disease in the differential diagnosis of orbital masses, particularly in endemic regions.
