UNASSIGNED: Hydatid cyst disease is a zoonotic disease caused by Echinococcus granulosus and is recognized as a significant health issue in many countries, particularly Mediterranean countries. Hydatid cysts in the musculoskeletal system are rare, with only a few reported cases. These usually occur as secondary cysts resulting from the hematogenous dissemination from primary sites.
UNASSIGNED: This paper reports a case of a 77-year-old man with a mass in his thigh that had been increasing dramatically in size for 4 months with no signs of local inflammation, fever, or any other symptoms. Findings from an MRI were consistent with a large abscess, so a true-cut biopsy was taken before referral. A pathological study after surgery revealed the lesion was a hydatid cyst, and a previously performed biopsy caused a rupture of the cyst.
UNASSIGNED: Misdiagnosing hydatid cysts, especially in non-usual areas, may lead to an unwelcome biopsy and consequences.
UNASSIGNED: This case report highlights the importance of considering hydatid cysts when encountering any enlarging mass, regardless of its location or rate of growth.

BACKGROUND: \"Hydatid cyst\" or cystic Echinococcosis is a parasitic infection caused by the larval stage of Echinococcus granulosus. The liver and lungs are the most common sites to occur. Incidence in muscles is exceptionally rare. Surgery has been the traditional approach for treatment of cystic echinococcusis.
METHODS: We report a rare case of 44 years old man with multiple hydatid cysts; liver, lungs, paraspinal muscles. The muscular cyst had manifested as a swelling in his back and was the principal clinical presentation as it caused pain and discomfort. He was treated with Albendazole, and a thoracic surgery for the management of the lung cysts had been performed. On admission and after his surgery, lymphadenopathy had manifested and following adequate diagnostic modalities he was diagnosed with Non-Hodgkin lymphoma. Then, after three months, physical examination revealed significant reduction in the size of his back cyst that was no longer visible.
CONCLUSIONS: Here we present a successful treatment for muscular hydatid cysts. While prior reports have managed it surgically; albendazole has played a significant role in our case, in addition to the diagnosis of the NHL in the course of managing multiple hydatid cysts.
CONCLUSIONS: The presence of non-Hodgkin lymphoma alongside hepatic cystic disease is rare, and the coexistence of NHL and muscular hydatidosis is unprecedented in medical literature.

UNASSIGNED: Hydatid disease of the male breast has not been documented in literature to date.
UNASSIGNED: We present a case of a 46-year old male patient who presented with a painful breast lump for 1 year. On imaging, it was suspicious for hydatid disease of the breast and was successfully diagnosed preoperatively on fine-needle aspiration cytology and histopathology as hydatid disease of the breast.
UNASSIGNED: Incidence of hydatid disease of the breast contributes to a minute number of total cases of hydatid disease. Male breast hydatid disease was unknown prior to this report. We did find similarities in the imaging features of our case and the ones described for female breasts. On ultrasonography, we found it analogous to the \'water-lily\' sign which has been described in hepatic hydatic cysts.
UNASSIGNED: Keeping hydatid disease as a differential in the setting of a suspicious breast mass even in a male patient proved to be rewarding as it negated the need for further cross-sectional imaging and a definitive diagnosis could be sought based on the fine-needle aspiration cytology and histopathological findings.

Hydatid disease, also known as hydatidosis or echinococcosis, is a zoonotic infection caused by cestode, namely Echinococcus granulosus (tapeworm). Humans are the incidental hosts that acquire the infection by being in contact with infected animals or through the fecal-oral route via contaminated feces. Hydatid disease of the spleen is a zoonotic disease of rare occurrence. Most often, the patients do not have any specific symptoms except dull dragging pain in the abdomen. In some unfortunate cases, the patient may present with an acute abdomen or anaphylactic shock state due to rupture of the cyst, which is a medical and surgical emergency. The mainstay of treatment remains albendazole and praziquantel medically, along with surgery, i.e., splenectomy. A 30-year-old female presented in the OPD with complaints of pain in the abdomen for the last two years with no other complaints. The pain did not respond to regular analgesics and antacids. The patient was admitted for further evaluation. A contrast-enhanced computed tomography (CECT) abdomen was done for the patient, which showed splenomegaly along with features suggestive of a splenic hydatid cyst. The lady was taken for a planned splenectomy. The histopathological features were suggestive of a hydatid cyst of the spleen. The mainstay of treatment is medically anthelmintic medications and surgical splenectomy along with the puncture aspiration injection re-aspiration (PAIR) technique.

Hydatidosis is a zoonotic parasitic disease caused by the cystic stage of Echinococcus species. Intrathoracic extrapulmonary hydatid cysts causing eventration are very rare. Here, we report a case of a 62-year-old female who presented with chest pain, intermittent coughing, general weakness, and fever. On auscultation, there were diminished respiratory sounds at the base of the left lung. A computed tomography scan showed a cystic formation with an ambiguous location involving the left lower thorax and the left hypochondrium. Complete surgical resection is the standard treatment for intrathoracic extrapulmonary hydatid cysts. Due to the direct bordering of the cyst with the pericardium in the left cadiophrenic angle, a cystotomy and evacuation of the cystic cavity were performed, followed by washing it with povidone and hyperosmolar saline. The location of the hydatid cyst has an important role in determining the surgical approach, as the unusual location could affect the possibility of radically removing the cyst.

Hydatid disease is endemic in some regions of the world. Even in endemic regions, splenic hydatid cysts are rare, especially in pregnancy. The most serious presentation is intra peritoneal rupture, which is a surgical emergency. Exploration with splenectomy is the favoured management. We present a case of splenic hydatid cyst, detected late in pregnancy, with intraperitoneal rupture in the postpartum period. Cystic lesions located anywhere in the body in endemic regions could be hydatid cysts. Prompt treatment should be planned immediately on detection in order to prevent potentially serious complications like rupture.

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.

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.
