Diagnostic challenge posed by the clinical presentation of foot drop in a patient with Hodgkin's lymphoma.

We report the case of a 56-year-old male with Hodgkin's disease who was being treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and who presented with paresthesias, bilateral leg weakness, and foot drop. MRI revealed a paravertebral abscess with intraspinal extension that was drained and treated with vancomycin. Foot drop was persistent after the treatment. The objective of this case report is to highlight the diagnostic challenge posed by the clinical presentation of foot drop in a medical patient with multiple co-morbidities.
