Intracranial lipomas are often associated with malformations of the brain such as dysgenesis of the corpus callosum, but rarely with vascular malformations. A man presented with left-sided facial pain at the age of 31. He developed left oculomotor nerve palsy at the age of 38 years and was referred to our hospital at the age of 48. Radiological findings revealed vascular anomalies of the left posterior cerebral and superior cerebellar arteries with intracranial lipoma-like lesion in the cerebral peduncle. Surgical treatment was complicated by the lesion location, so we administered conservative therapy. Despite treatment with corticosteroids, his symptoms have not improved. This unique case documents the presentation of vascular anomalies of the left posterior cerebral and superior cerebellar arteries associated with lipoma in the cerebral peduncle.
