Core Tip
Core Tip: Recurrent perihepatic “ascites” in a patient with spina bifida was resistant to exhaustive hepatic, cardiac, and surgical evaluation. The eventual diagnosis—a cerebrospinal fluid pseudocyst from a 27-year-old ventriculoperitoneal shunt—was made possible by renewed clinical suspicion and targeted beta-2 transferrin testing, despite the shunt being invisible on imaging. This case highlights the need to keep rare diagnoses in mind when standard workups fail, and the role of selective, specific tests in solving complex diagnostic puzzles.
