Foot mass Tendons and ligaments: The visualized extensor tendons are intact. The visualized flexor tendons are intact. The peroneal tendons are intact. The Lisfranc ligament is intact. There is no subluxation or dislocation in the tarsometatarsal articulations.Joints: There is no joint effusion. Alignment: There is normal alignment of the metatarsals. There is no hallux valgus deformity.Muscles: There is diffuse atrophy of the musculature.Bone Marrow: The bone marrow signal is normal. There is no fracture or contusion. There is no marrow replacing lesions.Soft tissues: Within the lateral superficial soft tissues adjacent to the fifth tarsometatarsal articulation is a lobulated soft tissue mass measuring approximately 2 cm. This lesion is slightly T1 hyperintense and markedly T2 hyperintense containing a few thin septations. There is a mild amount of associated surrounding subcutaneous edema. Following contrast administration, there is only thin peripheral and septal enhancement.
Superficial soft tissue lesion along the fifth tarsometatarsal articulation demonstrates imaging findings most consistent with a ganglion cyst.
