Abstract:
Gastric duplication cyst is an uncommon entity and management is principally surgical. Diagnosis is often delayed because of the non-specific nature of symptoms. The authors report one case of gastric duplication cyst incidentally diagnosed in a 23-year-old man. He had no specific symptoms but follow up of the unknown retro gastric mass showed an increase in size and cholelithiasis. Magnetic resonance imaging (MRI) was not useful for diagnosis but an endoscopic ultrasound suggested a GIST. The growing size of the mass led to a laparoscopic resection. Histopathology showed a gastric duplication cyst boarded with gastric and respiratory ciliated epithelium. This respiratory differenciation is extremely rare. Our patient is the 25th case reported in the literature. The embryologic origin, diagnosis tools and treatment of those rare cysts are briefly reviewed.
