Presentation of Diffuse B Cell Lymphoma as a Sciatic Nerve Tumor Localized on Electrodiagnostic Study: A Case Report

Video Transcription

Video Summary

The video transcript discusses a case report about the localization of a sciatic nerve tumor using electrodiagnostic studies. The patient, a 41-year-old female marathoner, presented with right calf cramping and pain, followed by foot drop and weakness. Despite negative ultrasound and lumbar MRI results, electrodiagnostic testing revealed abnormalities in the patient's tibialis anterior, gastroc, tibialis posterior, flexor digitorum longus, and peroneus longus muscles. An MRI of the thigh eventually showed a large sciatic nerve mass, which was confirmed to be diffuse large B-cell lymphoma. The patient underwent chemotherapy and radiation, and the tumor significantly reduced in size after six months of treatment. The video emphasizes the rarity and challenging diagnosis of neurolymphomatosis, as well as the potential usefulness of electrodiagnostic studies in localizing nerve tumors.
