Ultrastructural Pathology of Human T-Cell Lymphotropic Virus Type I Encephalomyelopathy in a White Patient with Adult T-Cell Leukemia/Lymphoma
1994
A white patient with human T-cell lymphotropic virus type I (HTLV-I)-associated adult T-cell leukemia/lymphoma for 10 years died 4 months after the onset of spastic myelopathy. Ultrastructurally, the neuropathologic findings consisted of dystrophic neurites (spheroids) filled with neurofilaments or electron-dense bodies, intense astrocytic reaction with abundant formation of corpora amylacea, and multilamellar bodies. Demyelination and spongiform change were absent. Viruslike particles resembling HTLV-I were detected adjacent to brain endothelial cells.
