From: Ultrasound in the diagnosis of a median neuropathy in the forearm: case report
The cross-sectional ultrasound image (A) of the proximal forearm demonstrates the normal echo-texture of the median nerve (arrow). The hyperechoic and homogenous ground glass appearance of the flexor digitorum profundus muscle (curved arrows) is also shown. The intra-operative photo (B) depicts a fibrotic band (straight line) across the anterior aspect of the median nerve (arrow). Arrowheads = arteries, * = pronator teres muscle. The ultrasound image was obtained with a Philips iU22 scanner (Philips Medical Systems, Bothell, WA) with a 12 MHz linear array transducer.
