Intracranial Lipoma Extending Extracranially in a Five-Year-Old Patient

Abstract

Intracranial lipomas are one of the rarest brain lesions. It is thought to form due to abnormal persistence and differentiation of the meninx. Here we report a unique case of a five-year-old male child with no known chronic medical illnesses and with no history of previous surgeries or allergic problems. He was brought to the pediatric emergency department after having episodes of focal seizures, which lasted only two minutes. On arrival to the emergency department, the child had no neurological deficits or any form of distress. A detailed neurological examination was conducted, and it was normal. Brain CT was requested according to the departmental policy, which showed a well-defined oval shape homogenous fat density in the midline along the falx cerebri at the vertex level, likely representing interhemispheric lipoma. Intracranial lipomas are rare and usually asymptomatic lesions that are formed of adipose tissue. The tumor is usually diagnosed as an incidental finding on CT or MRI scans as patients are usually asymptomatic. However, if symptomatic, the most common presentation of this tumor is seizures. The management is usually conservative, and surgical intervention is not usually recommended.
