A Central Nervous System Tumor Mimicking a Lumbar Spine Pathology Causing Acute Foot Drop: A Case Report.

Introduction: Common causes for foot drop are peroneal mono-neuropathy or sciatic neuropathy and lumbar root compression. Central nervous system pathologies leading to isolated drop foot are rare etiologies with unknown incidence.

Case Report: Our patient had a brain tumor manifested as acute onset foot drop accompanied by low back pain, leading us to look for a lumbar pathology. In this case study, we describe the clinical management from the first encounter to diagnosis.

Conclusion: Full diagnostic work up of acute foot drop should take into consideration peripheral versus central etiologies.
