Abstract

Meralgia paresthetica (MP, or Bernhardt-Roth syndrome) is a painful mononeuropathy resulting from the compression of the lateral femoral cutaneous nerve (LFCN) as it crosses between the anterior superior iliac spine and the inguinal ligament to enter the thigh. Although the diagnosis of MP is straightforward based on its typical presentation, other neuropathies such as lumbar disc herniation or stenosis may mimic MP and complicate the diagnosis. We report a case of delayed diagnosis of MP due to concomitant lumbar disc herniation. A 49-year-old female patient presented with a 2-year history of gradually worsening pain and paresthesias in her left anterior thigh and left buttock. Magnetic resonance imaging of the lumbar spine revealed disc herniation at the level of L4/5. The diagnosis of MP was made after relief from buttock pain using repeated epidural blocks. Although MP was diagnosed late, decompression of the LFCN resulted in immediate and permanent relief of chronic anterior thigh pain. Unexplained, chronic anterolateral thigh pain and paresthesias warrant careful investigation for the possibility of MP.
