Congenital infiltrating lipomatosis of the face: Case report.

A rare disorder called congenital infiltrating lipomatosis of the face is characterized by a diffuse fatty infiltration of the soft tissues of the face. Muscle involvement and related bony hyperplasia may coexist. This particular form of lipomatous tumor is rare and typically appears in childhood. It is congenital in nature. Collections of mature, nonencapsulated lipocytes that infiltrate local tissues and frequently recur following surgery define congenital infiltrating lipomatosis, a unique clinicopathologic condition. The best modalities are, CT scan and MRI since they can determine the extent of the lesions and reveal their fat content. The treatment of this disease is surgical as soon as possible to restrict their infiltrative growth and improve the appearance of the face. We describe a case of massive facial invading lipoma that was investigated using MRI.
