A rare case, diagnosed as calcified callosal lipoma, when the patient presented with acute stroke

Intracranial lipomas are rare and generally located at pericallosal midline lesions. They are usually asymptomatic; when symptoms occur, they may depend on localization and include headache, seizure, psychomotor retardation, and cranial nerve deficits [1]. These mass lesions, which can be diagnosed with computed tomography (CT) or magnetic resonance imaging (MRI), cannot be treated with radical surgery, because they are usually adherent to the surrounding neurovascular structures and asymptomatic, and surgical excision may result in high mortality and morbidity risk. Incidental asymptomatic lipomas are not treated with surgical excision. However, surgery should be considered in the case of uncontrollable seizures, hydrocephalus, progressive dementia and increased intracranial pressure. In this article, we present a rare case of incidental pericallosal lipoma detected by neuroimaging at the time of consulting for acute cerebrovascular disease.
