title: Postoperative dissemination of fat particles in the subarachnoid pathways.
abstract: A case of postoperative dissemination of fat particles into the cerebrospinal fluid pathways is reported. Following removal of a foramen magnum meningioma, a postoperative MR scan showed fat droplets in the basal cisterns and in the frontal horns of the lateral ventricles. The patient was asymptomatic and a repeat MR scan 7 months later was normal, with resolution and clearing of the previously noted cerebrospinal fluid fat.
