Cerebrospinal fluid (CSF) peritoneal pseudocysts are a rare complication of ventriculoperitoneal shunts. They can manifest with symptoms of shunt malfunction or, more commonly, vague symptoms of abdominal discomfort such as pain or distention. The imaging features of peritoneal CSF pseudocysts may be nonspecific. In this case, we report a peritoneal CSF pseudocyst, which was initially mistaken for a complex hepatic cyst on both ultrasonography and MRI. The correct diagnosis was confirmed with a shuntogram and CT of the abdomen.
