Low back pain radiating to the leg: An atypical cause

Research output: Contribution to journalArticlepeer-review

Abstract

This study reports the case of a 47-year old female with low back pain radiating to groin and anterior regions of the left thigh and leg. At symptoms onset, electromyography showed left L3-L4 radiculopathy, and nuclear magnetic resonance revealed disc protrusion at the same level with impingement of the spinal nerve root. The clinical symptoms were ascribed to lumbar disco-radicular conflict. The patient underwent steroidal anti-inflammatory treatment with epidural steroid injections, chiropractic spinal manipulations and rehabilitation program, with no relief. Thirteen months after the onset of pain, a computed tomography of sacroiliac joints showed osteolytic lesion in the iliac bone of left joint, and a bone scintigraphy highlighted foci of intense uptake at left iliac bone and left proximal extremity of the femur. The bone biopsy and pathological examinations showed findings consistent with large B-cell non-Hodgkin lymphoma. This case report highlights the fact that in making differential diagnosis of low back pain radiating to the leg we have to consider the rare possibility that pain can be due to non-Hodgkin lymphoma that involves simultaneously the iliac bone and proximal extremity of the femur.
