SUMMARY: Intracranial lipomas are rare lesions. Intracranial lipoma associated with a subcutaneous lipoma is extremely rare. Various vascular abnormalities have been described in association with intracranial lipoma, including distension, kinking, or narrowing of arteries and veins; arteriovenous malformation; and aneurysm. To our knowledge, association of sagittal sinus fenestration, falcine sinus, and absent straight sinus with intraextracranial lipoma has not been reported before. We report the imaging findings of an infant with interhemispheric and subcutaneous lipoma associated with falcine sinus and sagittal sinus fenestration.
