A ganglion is a well-defined, lobulated mass located adjacent to a tendon, ligament or a joint. A fluid-filled stalk or pedicle that connects to the adjacent joint or tendon sheath is a reliable sign of a ganglion. MRI signal characteristics of intratendinous ganglion are typical of other ganglions with homogenous low signal intensity on T1-weighted images and high signal intensity on T2-weighted images. The supraspinatus tendon partial thickness tear is suggested to be more responsible for the patient's complaint.
