Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is well known as a safe diagnostic procedure. We report the first case of pancreatic pseudocyst after EUS-FNA of the pancreatic body mass. A 60-year-old male underwent EUS-FNA for incidentally detected pancreatic solid mass which was suspected as neuroendocrine tumor. Two weeks later, the patient visited emergency room with acute abdominal pain and right upper quadrant tenderness; leukocytosis and elevated C-reactive protein, amylase, and lipase levels were noted. Computed tomography discovered newly developed 11.5×9.5 cm sized cystic mass communicating with the main pancreatic duct. Cyst fluid analysis revealed amylase level of 3,423 U/L and fluid culture isolated Streptococcus parasanguinis. The cystic mass corresponds with pancreatic pseudocyst. FNA induced main pancreatic duct injury and fluid leakage may cause it. Endoscopists who perform EUS-FNA must remember that pancreatic main duct injury can occur as one of severe complications and that it could be treated successfully with endoscopic internal drainage.
