Abstract

OBJECTIVES:

To evaluate the clinical, laboratory, and radiological features of 4 cases of biopsy-proven lymphomatous lumbosacral radiculoplexopathy.

METHODS:

Retrospective chart review.

RESULTS:

All patients suffered from diffuse large B-cell lymphoma. A mean diagnostic delay of 10 months was encountered. Presenting symptoms in all 4 patients included back pain, radicular leg pain, and leg weakness, similar to spondylotic radiculopathy. Electrodiagnostic study showed axon loss radiculoplexopathy and magnetic resonance imaging of the lumbar spine or pelvis demonstrated nerve or nerve root enhancement. Increased uptake by lumbosacral roots/plexus on fluorodeoxyglucose-positron emission tomography aided diagnosis in 3 cases. Cytology was positive in 1 of 10 cerebrospinal fluid samples. Combined chemotherapy and radiation treatment led to clinicoradiological improvement, with residual neurological symptoms in all patients.

CONCLUSIONS:

Lymphomatous lumbosacral radiculoplexopathy should be considered in patients with progressive lumbosacral radicular symptoms. Magnetic resonance imaging and fluorodeoxyglucose-positron emission tomography, but not cerebrospinal fluid, are helpful in achieving early diagnosis. Treatment responses seem favorable.
