Giant adrenal pseudocyst, about a new case report

Abstract

Introduction: Adrenal pseudocysts are rare benign lesions. Mostly, these are small lesions discovered incidentally by imaging. The giant forms are rare. Through a new observation, we describe the different epidemiological, clinical, pathological features and treatment of this entity.
Observation: A patient of 52 years old, without notable medical history, suffered left flank pain associated with bilious vomiting of 15 days duration. Abdominal examination revealed a voluminous mass at the left hypochondrium. Imaging revealed a huge heterogeneous mass, located between the spleen and kidney, compressing adjacent organs. Given the diagnostic difficulty, a laparotomy was undertaken to excise the mass. Histological examination revealed a giant benign adrenal pseudocyst.
Comment: Giant adrenal pseudocysts are very rare. Clinical and radiological signs are not specific. Only pathological study can confirm the diagnosis and exclude malignancy. The treatment is based on surgery for large or symptomatic cysts.
