Xanthomatous infiltration of the rotator cuff and long head of biceps with rotator cuff tear in a patient with mixed hyperlipidemia: A case report with MRI imaging

Abstract

Xanthomatous infiltration may rarely affect the rotator cuff muscles and long head of the biceps tendon. It is the deposition of cholesterol within the rotator cuff muscles and long head of the biceps tendon resulting from hyperlipidemia, specifically high triglyceride and total cholesterol levels. As more commonly seen with xanthomatous infiltration and tear of the Achilles tendon, there may also be an association with rotator cuff tendon deposition and tear. MRI images of xanthomatous infiltration with rotator cuff tear in a 77 year old man with hyperlipidemia are detailed in the following case report. © the author(s), publisher and licensee Libertas Academica Ltd.
