MR of laryngeal and scrotal involvement in multiple symmetrical lipomatosis.

Abstract

Multiple symmetrical lipomatosis is a rare disorder characterized by progressive anomalous deposition of fat typically located in the neck and shoulders. Magnetic resonance imaging allows exact definition of the abnormal fatty tissue and the involvement of deep structures. We describe the MR findings in two patients with the typical fat deposition in the neck and upper thorax which also presented unusual location of abnormal fat. One patient had laryngeal involvement with fatty infiltration of true and false cords. The other patient had inguinal and scrotal large deposition of fat.
