A 50‐year‐old man developed intermittent paresthesia of the outer portion of the right thumb. Paresthesia increased with thumb abduction and flexion. The remainder of the physical examination was normal. Methods Routine motor and sensory examinations of the median and ulnar nerves were within normal ranges. Results Ultrasonographic studies revealed that a tenosynovitis of the flexor pollicis longus of the right thumb was compressing the radial digital nerve of the thumb. Conclusions Ultrasonographic evaluation was used in conjunction with nerve conduction studies to diagnose digital neuropathy. Ultrasound is a beneficial, complementary tool to electrodiagnostic studies, especially for uncommon focal neuropathies. Muscle Nerve 47: 772–775, 2013
