Hydatid cyst of gall bladder masquerading as carcinoma: A rare case report with review of literature

Abstract

Hydatid disease is a parasitic infestation caused by Echinococcus, most commonly Echincoccus granulosus. Liver is the most common location followed by lungs. Hydatid involvement of gall bladder is a very rare entity, which masqueraded as gall bladder cancer. Here, we attempt to highlight the relevance of this rare disease and discuss this unique case of a 60-year-old male, who presented with gall bladder mass, abdominal pain, and vomiting. The patient was eventually diagnosed as Hydatid disease. The patient has been treated on medical management and has shown improvement. The manuscript has discussed diagnosis and management of disease along with review of literature.
