Nonmidline intracranial lipoma misdiagnosed as meningioma: case report.

A patient was initially believed to have a cavernous sinus and sphenoid ridge meningioma and presented to the University of Connecticut Health Center for radiation therapy. Initial radiation planning computerized tomography (CT) revealed the mass to be a lipoma. Conservative management with serial monitoring was the revised plan. This paper describes the rare entity of an intracranial lipoma not located in the midline, and some pitfalls in imaging of intracranial masses.
