A Retroperitoneal bronchogenic cyst mimicking an adrenal cyst - A case report

Abstract

Abstract : Retroperitoneal bronchogenic cysts are very rare and a good mimicker of adrenal and pancreatic cystic lesion. Though benign, malignant potential of this variety has been reported. We present a case of a 43 year old female with left hypochondrial pain with imaging modality suggestive of an 8.5 x 6.5 cm left adrenal cyst. Patient was planned for laparoscopic retroperitoneal cystectomy. Intra-operatively an 8 x 8 cm thick walled cyst was seen firmly adherent to the left adrenal, stomach and left hemi diaphragm. Histopathology was suggestive of bronchogenic cyst. To our knowledge less than 40 cases of retroperitoneal bronchogenic cysts have been reported worldwide.
