Abstract
Foot drop is a common symptom that often requires further neurologic evaluation via electromyography (EMG). This case details a 57-year-old male who presented with left lower extremity pain, paresthesia, and foot drop. Lumbar radiculopathy was initially suspected, prompting a nerve conduction study (NCS)/EMG. A palpable mass at the left buttock was noted during the exam. Magnetic resonance imaging (MRI) of the pelvis revealed a large left gluteal mass extending into the pelvis through the greater sciatic foramen. Computed tomography-guided needle biopsy was performed, followed by surgical resection. Pathologic examination later confirmed the mass as an intramuscular myxoma. While rare, myxomas remain a notable differential in the evaluation of chronic radiculopathy.
