Scintigraphic Cerebral Spinal Fluid Leak Study in a Child With Recurrent Meningitis After Resection of a Frontal Meningocele

Abstract

An In-111 DTPA cerebrospinal fluid (CSF) leak study was performed on a 3-year-old boy admitted with recurrent meningitis. He was born with a congenital encephalocele that was surgically resected at 7 days-of-age. A residual skull floor defect with a recurrent tumor of the nasal radix was clinically suspected. Computed tomography and MRI scans could not confirm or rule out the presence of a CSF leak. The scintigraphic study clearly demonstrated a leak into the left naris. A large leptomeningeal cyst extending down into the left nares was resected and a defect in the left frontal calvarium, identified as the source of the CSF leak, was repaired at surgery.
