An Unusual Presentation of Massive Hydatid Cyst of Liver in a 39-year-old Female Patient

Abstract

Hydatidosis, a zoonotic infection of the larval stage of Echinococcus granulosus, has a worldwide distribution. Due to the late onset of clinical manifestation, the cyst can involve the greater part of the tissue. This case study was performed on a massive hydatid cyst (HC) (85×115mm), reported in a 39-year-old woman. She was referred to the clinic with right upper quadrant pain and gastric pressure. Magnetic resonance imaging (MRI) revealed that the vast space of the liver had been ‎occupied by the massive cyst in the right lobe of the liver. Routine liver assays were normal. IgG enzyme-linked immunoassay (ELISA) test using antibody was negative (0.19 mg/dL). Resection laparoscopic surgery was scheduled for the patient due to severe pain. The massive HC was confirmed in microscopic examination of the cyst.
