PMID: 36723893.


A 37-year-old man presented with a 2-week history of abdominal pain, headaches, nausea, vomiting, and leukocytosis. Medical history includes congenital hydrocephalus, with a ventriculoperitoneal shunt placed several years ago. Radionuclide cerebrospinal fluid cisternography shows curvilinear activity in the abdomen, in the pattern of small and large bowel loops, suggesting that the tip of the catheter is inside a small bowel loop. No activity is seen in the intraperitoneal compartment. CT of the abdomen and pelvis followed by laparoscopic surgery confirmed the findings.
