SCINTIGRAPHIC CEREBRAL SPINAL-FLUID LEAK STUDY IN A CHILD WITH RECURRENT MENINGITIS AFTER RESECTION OF A FRONTAL MENINGOCELE

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-ag e. A residual skull floor defect with a recurrent tumor of the nasal r adix 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 leptom eningeal cyst extending down into the left nares was resected and a de fect in the left frontal calvarium, identified as the source of the CS F leak, was repaired at surgery.
