Neurological
CT of a CSFoma / cerebrospinal fluid pseudocyst in the anterior abdominal wall
Axial (above) and coronal (below) CT with contrast of the abdomen shows a round low density fluid collection in the subcutaneous tissues of the right anterior abdominal wall with inflammatory changes noted around the fluid collection. In the center of the fluid collection is a coiled ventriculoperitoneal shunt.

The diagnosis was ventriculoperitoneal shunt malfunction in the form of a CSFoma in the anterior abdominal wall due to VP shunt tip migration out of the abdomen.
