Intracranial lipoma are usually localized in the corpus callosum and rarely extends to the subgaleal region. Only eight cases of lipoma of the corpus callosum with extracranial extension were reported in the literature. Seizures and mental retardation were the most common clinical findings in these patients. Data from the literature show that resection of intracranial lipoma has catastrophic results. The resection must be restricted to the extracranial portion. We report a child with lipoma of the corpus callosum with extracranial extension with no neurologic deficit submitted to resection of the extracranial extension.
