[An autopsy case of pericallosal lipoma with mental retardation].
The patient was a 69-year-old male who had visited our psychological department due to mental retardation. Pericallosal lipoma was indicated by MRI taken during treatment. On December 30, 1998, the patient fell from steps and struck his forehead hard, and then limb palsy occurred. He was emergently brought to our hospital. Under the suspected diagnosis of traumatic cervical spinal cord injury, preventive therapy was performed to observe the clinical course in which paralysis gradually improved. On January 22, 1999, however, he died of cardiopulmonary arrest due to sudden suffocation. In general, the connection of choroid plexus lipoma and pericallosal lipoma is bilateral in most cases. In our patients, MRI suggested that a connection with cerebral ventricles through choroidal fissure existed with no right and left difference, however, autopsy findings revealed that the lipoma existed along the left cerebral arch with obvious connection only with the left choroid plexus. The present case seemed to be a very rare case.
