Poorly encapsulated enhancing soft tissue mass with multiple small T1 and T2 dark intralesional nodules (likely calcific foci) seen in the palmar side of the wrist overlying the scaphoid and trapezium/trapezoid bones, with the lesion surrounding the palmar aponeurosis and located superficial to the transverse carpal ligament. The lesion encases the abductor pollicis longus tendon at the wrist. No extension into the carpal tunnel.
A second smaller similar lesion also with intralesional probable calcified nodules seen at the ulnar side palmar aspect of wrist overlying the pisiform bone and deep to the flexor carpi ulnaris tendon.
