MRI reveals thickening with abnormal intrasubstance increased fluid signal of the first dorsal compartment tendons of the wrist (abductor pollicis longus and extensor pollicis brevis). There is increased fluid within the tendon sheath.
Linear intrasubstance increased fluid signal and thickening of extensor carpi ulnaris tendon a the levels of ulnar styloid and carpal bones due to tendinosis.
Case Discussion
MRI imaging findings are consistent with De Quervain tenosynovitis.
