DOI : 10.5606/tftrd.2023.11554 Neuralgic amyotrophy (NA) is a peripheral nerve disorder that has a classical presentation as motor deficit after severe pain, but it is still overlooked or misdiagnosed. Formerly, the diagnosis was based on the clinical picture and electrophysiology; however, sophisticated imaging and surgical modalities showed structural abnormalities such as hourglass-like constrictions of the nerves. In this article, we present a case presenting with drop hand mimicking radial nerve entrapment. The patient was diagnosed with NA and surgery revealed hourglass-like constrictions. The clinical findings were improved after neurorrhaphy and physical therapy. In conclusion, hourglass-like constrictions can be prognostic factors of NA and should be searched carefully.
