Spontaneous drainage of a pancreatic pseudocyst into the stomach

A 45-year-old woman presented with a ten-day history of abdominal pain. Laboratory examination upon admission indicated increased serum amylase level of 213 U/L (35-135 U/L). Tumor markers were within the normal range. Computed tomography (CT) of the abdomen showed a cystic mass in the greater curvature with homogeneous water like density. Similar round-like cystic masses with homogeneous water like density were also revealed in pancreas and spleen. Esophagogastroduodenoscopy revealed a eminence lesion in the fundus and corpus of the stomach. Endoscopic ultrasonography revealed a homogeneous hypoechoic mass in the fundus and corpus junction, measuring 4.6 cm × 2.7 cm. Magnetic resonance (MR) images showed multiple cystic masses with ring-like enhancement in the greater curvature, spleen and pancreatic tail. The patient was diagnosed as multiple pseudocysts due to pancreatitis and treated conservatively with anti-infection, acid suppression and inhibition of pancreatic secretion. He recovered with resolution of abdominal pain. The patient was feeling well at 8 months of follow-up.
