Abstract

We report a case of neurolymphomatosis of lumbosacral plexus. A 63-year-old man, who had no past history except for diabetes mellitus, complained of severe pain and weakness on left lower extremity. Idiopathic lumbosacral plexopathy was diagnosed by electromyography. There were no abnormal findings except for FDG-PET/CT and MRI. They showed high uptake and thickening lesion in sciatic nerve and sacral plexus. However, about 7 months later, mass like lesion in left thigh was detected by FDG-PET/CT and MRI. Also, multiple hypermetabolic lesions were found in brain. Through brain biopsy, diffuse large B-cell lymphoma was confirmed. When a patient with idiopathic lumbosacral plexopathy complains of severe pain, it is necessary to consider FDG-PET/CT and MRI to differentiate neurolymphomatosis, even in patients who have no past history of lymphoma before. Especially, if FDG-PET/CT and MRI show sciatic and/or lumbosacral plexus lesion, neurolymphomatosis of lumbosacral plexus should be considered.
