Although shunt-associated abdominal complications are well documented, extrahepatic pseudocysts are a rare shunt complication in adult patients. Therefore, we herein report the case of a 54-year-old male patient who presented with a bulging mass around the previous surgical site at the right upper quadrant of the abdomen. He had a 4-year history of VP shunt surgery for posthemorrhagic hydrocephalus. A computed tomographic scan revealed a large extrahepatic pseudocsyt. Our case represented a rare entity of extrahepatic pseudocyst in adult patients underwent VP shunt surgery. The clinical presentation, diagnostic tools, and treatment methods were discussed. ER -
