We encountered an Adult T-cell Leukemia/Lymphoma (ATLL) patient with brain lesion without the involvement of any other organ. The patient exhibited amnesia, short-temper, and gait disturbance due to left hemiplegia. Brain Magnetic Resonance Imaging (MRI) revealed a broad edematous lesion in the right frontal lobe. Whole body examination by Computed Tomography (CT) demonstrated no other lesion except for the brain lesion. ATLL cells were not detected in peripheral blood. A tumor biopsy was conducted via craniotomy, and based on biopsy results; the patient was diagnosed with peripheral T-cell lymphoma positive for CD3 and negative for CD20 and EBV-encoded RNA. Human T-Lymphotropic Virus type 1 (HTLV-1) antibody was positive, and qualitative analysis of HTLV-1 proviral DNA, using DNA extracted from paraffin-embedded specimens, showed HTLV-1 positivity. Therefore, the patient was finally diagnosed with ATLL.
