HTLV-I-associated myelopathy and polymyositis in a US native.
A patient who had always lived in the United States had an HTLV-I infection and a chronic myelopathy clinically mimicking amyotrophic lateral sclerosis. Needle EMG and nerve conduction studies were consistent with anterior horn cell disease but muscle biopsy showed denervation and an inflammatory myopathy. Serum HTLV-I antibody tests were positive and HTLV-I DNA was present in peripheral leukocytes. This is the 1st reported US native with HTLV-I-associated myelopathy and polymyositis.
