Lipoma

Lipomas are rare, benign (noncancerous) tumors composed of fatty tissue. They are sometimes associated with other congenital abnormalities of the nervous system.

Location

Lipomas most commonly appear in the corpus callosum. However, they can appear in other areas of the brain, usually close to the midline.

Description

Lipomas vary in size. Single or multiple tumors may be present.

Symptoms

A lipoma may cause no symptoms and often goes unnoticed until a scan is performed for other medical reasons.

Incidence

Lipomas are rare.

Cause

The exact cause of lipoma is not known.

Treatment

Conservative treatment is usually recommended because these tumors are benign and rarely cause symptoms. Surgery may be suggested in some cases.
