Abstract
|
|
|
|
The lateral sural cutaneous nerve (LSCN) is one of the cutaneous branches of the peroneal nerve. LSCN neuropathy is a rare neurological abnormality. This condition is hard to diagnose on imaging studies such as ultrasound or magnetic resonance imaging (MRI), so an electrodiagnostic approach may be necessary to evaluate LSCN neuropathy. We report LSCN neuropathy in a 35-year-old man with a 2-month history of hypesthesia and paresthesia in the right lateral calf. He was diagnosed with LSCN neuropathy by a special nerve conduction study of the LSCN. After sono-guided injection with a local anesthetic and steroid mixture, the symptoms improved.
