Primary Hydatid Cyst of the Stomach: A Rare Case Report and Review of the Literature

Abstract

Hydatid cyst is an infestation disease of the humans that caused by Echinococcus Granulosus and can involve all organs and tissues that produce cyst everywhere in body. The most common organ of body for development of a hydatid cyst is the liver (75%) and the lung (15%). We present a primary stomach hydatid cyst resected via laparotomy with the affected stomach wall. As far as we know, this is the first report of a primary stomach hydatid disease in the case presentation: A 64-year-old woman presented with a palpable mass on the epigastric and left upper quadrant of the abdomen. She had an 8-month history of intermittent abdominal pain attacks, discomfort, weight loss, anemia and early satiety. Abdominal examination revealed a palpable, immobile mass at the epigastrium and left hypochondriac region. Laboratory findings were unremarkable. Abdominal U&S and computed tomography (CT) scans revealed a heterogeneous mass originated from the stomach wall, spleen, pancreas or liver measuring 15x8cm. No pathological appearance was detected in the chest x-ray. Upper GI endoscopy was also unrevealing during diagnostic laparotomy. The pancreas, liver and spleen were intact, but we found a huge cystic mass located at the anterior surface of body of stomach. The mass was taken out from inside of the abdomen. Stomach defect closed the pathology report revealed a hydatid cyst. Keywords:

A Rare Simultaneous Occurrence of Splenic and Pelvic Cavity Hydatid Cyst

“…The main sites where hydatid cysts could be found are the liver and lungs. However, it could be found in other organs, but hydatid cysts are less likely to be found in the spleen and pelvic cavity than elsewhere [3,11]. Hydatid cysts in the pelvic cavity are usually caused by kidney and spleen hydatic cyst rupturing; however, it could be a primary type.…”

“…Choosing which surgical technique is more appropriate for the patient depends on the patient's condition and surgical team, but the open splenectomy for spleen treatment and total excision of hydatid cyst in the pelvic cavity were used in this case [14]. Medications such as mebendazole or albendazole are usually prescribed to patients adjuvantly to prevent recurrences [3]. In this case, the patient was advised to use albendazole to prevent recurrences as much as possible.…”

“…[1,2]. Approximately 1% of patients admitted to the operation room in Iran are patients with hydatid cysts [3]. Hydatid cyst is a serious infectious disease caused by Echinococcus granulosus larvae [4].…”

“…However, it is less likely to be found in other organs such as the spleen (2%-4%) and kidneys (0.5%-8%). Hydatid cyst in the pelvic cavity could be the primary type, or it could be caused by kidney and spleen hydatic cyst rupture [3,5]. The symptoms and clinical appearances of patients depend on the location of the hydatid cyst.…”
