Nevus sebaceus in association with an intracranial mass

A 7-week-old male infant with a seizure disorder and an extensive sebaceous nevus of the scalp was examined. Computerized axial tomography (CAT) scan identified an intracerebral mass which proved to be a hamartomatous malofrmation fo the brain. The association of intracranial masses with sebaceous nevi should be recognized. CAT scan is useful in the evaluation of infants with extensive lesions of the scalp or midline facial area, especially in the presence of neurologic abnormalities.
