Reason: evaluate sesamoid apparatus - rule out AVN History: pain at medial and lateral sesamoids left A skin marker was placed along the plantar aspect of the first MTP joint presumably corresponding to the patient's area of concern. Note is made of increased bone marrow signal abnormality within the medial sesamoid of the first MTP joint with corresponding decreased signal abnormality and T1-weighted images. These findings appear most consistent with a sesamoiditis. There is inflammatory change in the surrounding soft tissues. The lateral sesamoid is normal in appearance. No additional bone marrow signal abnormality is identified. The flexor and extensor tendons appear intact. There is a moderate amount of fluid within the first MTP joint with low signal intensity debris internally suggesting a synovitis. The remainder of the visualized soft tissues are unremarkable.
Findings indicating a sesamoiditis affecting the medial sesamoid of the first MTP joint as well as a synovitis of the first MTP joint.
