Unmasking Carpal Tunnel Syndrome by High-Resolution Ultrasonography in Misdiagnosed Pure Neuritic Leprosy: A Case Report.

We present a case of a woman in her 70s who was initially diagnosed with pure neuritic leprosy due to bilateral hand numbness and tingling with associated muscle weakness. However, after undergoing high-resolution ultrasonography (HRUS), it was found that she had bilateral carpal tunnel syndrome (CTS). This case highlights the importance of considering other possible causes of peripheral neuropathy, such as CTS, in patients with suspected Hansen's disease. It also establishes the role of HRUS in the prompt diagnosis of CTS. Appropriate treatment of CTS can prevent unnecessary and potentially harmful treatment for Hansen's disease.
