A case report of a Cerebellopontine angle lipoma revealed by vertigo

Abstract

Cerebellopontine angle (CPA) lipoma is an extremely rare lesion representing only 0.1% of all the CPA tumors. We present a case of a 56‐year‐old woman with a 6‐month history of vertigo. Cerebral MRI showed a left CPA lipoma. The patient was managed conservatively.

“…Intracranial lipomas (ILs) are benign, slow-growing neoplasms that typically cause progressive neurological symptoms with loss of hearing ability, dizziness, tinnitus, trigeminal neuralgia, and occasionally, involvement of the facial 6 and trigeminal nerves. [10][11][12][13] Macroscopically, although presenting as well-defined masses of adipose tissue incorporating the fibers of the cranial nerves due to the high degree of vascularization, they can be misinterpreted as hamartomas. 6,14 Microscopically, ILs consist of mature adipose tissue, large cells rich in lipids, and little or no fibrous stroma, similar to the lipomas found in other body sites.…”

“…The extra-axial sites, are documented in the Sylvian cistern and the cerebellopontine angle (CPA). 3,6 The cerebellopontine angle harbors 8-10% of all intracranial tumors, 7 including vestibular schwannomas (75-90% of cases). 8 In this site, the CPA lipoma is considered a striking finding, showing an estimated incidence between 0.05% 5 and 0.1%.…”
