Abstract
Intracranial lipomas are uncommon benign lesions of the central nervous system. Intracranial lipomas are usually asymptomatic and an occasional finding. They are frequently associated with more severe congenital anomalies like corpus callosum agenesis, and may present with seizures, headache, and behavioral disturbances. The MRI techniques are superior to CT and US in terms of exact anatomical localization of the lesions, and the origin of the lipoma and its relationship to surrounding structures. .
Highlights
Intracranial lipoma is a rare congenital lesion characterized by the presence of fatty deposits in different places in the central nervous system
Interhemispheric lipomas are often associated with partial agenesis of the corpus callosum (1)

Summary
Intracranial lipoma is a rare congenital lesion characterized by the presence of fatty deposits in different places in the central nervous system. Sremska Kamenica, Serbia; The manuscript was received: 24.11.2006, Provisionally accepted: 29.11.2006, Accepted for publication: 01.12.2006 The most common sites for intracranial lipomas are around corpus callosum, in the quadrigeminal cistern, hypothalamic-suprasellar region, and the cerebellopontine angles. The lesions are believed to result from lipomatous mal-differentiation of primitive meningeal tissue in the interhemispheric fissure.
