Lipomas of the corpus callosum are rare congenital lesions, representing about 5% of tumors in this area. They are typically asymptomatic and often discovered incidentally. A case of a 74-year-old patient with altered consciousness showed an anterior lipoma on CT, characterized by a lobulated, hypodense mass with calcifications. These lipomas are categorized into anterior and posterior types, with anterior ones being larger and often associated with agenesis of the corpus callosum. CT and MRI are crucial for diagnosis and evaluation.
