a Normal radial nerve (between white arrowheads) at the level of the spiral groove on the left with a mildly hypoechoic radial nerve surrounded by echogenic soft tissue (white arrow) in the distal arm as seen in the panel on the right. Based on ultrasound findings, radial nerve entrapment in scar tissue or hematoma was suspected. b The radial nerve (encircled), just before its division into the superficial and deep components is hyperintense on PDFS image with surrounding hypointense soft tissue. There are also changes of haemophilic arthropathy as evident by the hyperintense joint effusion (arrowheads), cortical irregularities and cartilage thinning (black arrow). On corresponding SWI image, there is blooming in the area around the radial nerve, which corresponds to the echogenic soft tissue on ultrasound (red arrowhead). This was a case for radial neuropathy due to entrapment in local hematoma in a case of haemophilia
