Abstract
BackgroundGastric duplication cyst is a rare congenital anomaly. It is usually located in close proximity to the stomach. Nevertheless, there have been seldom reports in the literature that describe unusual locations. Retroperitoneal gastric duplications cysts are extremely rare and are usually confused with renal or adrenal cysts.Case presentationIn this case report, we are presenting a 2-year-old girl with a complaint of bouts of abdominal pain, found to have a retroperitoneal supra-adrenal cyst on imaging. She underwent laparoscopic resection of the cyst with uneventful post-operative course. The histopathological diagnosis was surprisingly gastric duplication cyst.ConclusionIn our review of the literature, the variability of this condition and its clinical manifestation are apparent. We also conclude that this diagnostic entity should be part of the differential diagnosis of intraperitoneal or retroperitoneal cysts and that laparoscopic resection of retroperitoneal cysts is the preferred approach.

Summary
Gastric duplication cyst is a rare congenital anomaly. These cysts are usually lined with gastric mucosa and have all the layers of the stomach. It may or may not communicate with the organ of origin. Retroperitoneal gastric duplication cyst mimicking renal or adrenal cysts are rarely reported in the literature [1,2,3]. An abdominal CT-scan was done which showed a left supra-renal cyst, measuring 5.4 × 5.4 × 4.8 cm. It was in the superior pole of the left kidney, abutting the pancreas, and the medial aspect of the spleen (Fig. 1). On follow-up, she was doing well and pain-free
