Angiolipoma of the right inferior colliculus: a rare central cause of hearing loss and limb ataxia.

ABSTRACT

Intracranial angiolipomas are rare entities and are infrequently symptomatic. These benign lesions are adherent to the surrounding neurovascular structures as they share the same blood supply, which limits their resectability, and impose a possibility of persistence of symptoms. However, due to recent advancements in the neuro-radiological fields and microneurosurgical techniques it has been possible to localise precisely and excise these lesions with low morbidity and mortality. The authors present an interesting rare case of intracranial angiolipoma of the right inferior colliculus situated in the quadrigeminal plate cistern. The patient had presented with ipsilateral hearing loss and upper limb ataxia. Interesting clinical findings, neuro-imaging studies and peroperative features are presented and discussed along with a brief review of the literature.
