A Case of Rudimentary Lateral Parietal Cephalocele: Extracranial Meningothelial and Glial Tissue without Intracranial Communication or Bony Defect

Abstract

The authors report a case of a 7-month-old infant with a right lateral parietal scalp lesion intermittently leaking fluid similar to cerebrospinal fluid that histologically demonstrated meningothelial and glial cells. At surgical removal, however, no fibrous stalk or bony defect could be identified connecting the lesion with the intracranial compartment. While the embryologic mechanism of this lesion is unclear, the prognosis for normal neurological development appears excellent.
