title: Adult T-cell lymphoma involving the leptomeninges associated with a spinal cord schwannoma.
abstract: Adult T-cell lymphoma (ATL-L) developing initially in the meninges is rare. An autopsy case of ATL-L with an acute onset of meningitis and generalized lymphadenopathy in association with a cervical cord schwannoma is reported here. A 78-year-old woman with sensori-motor weakness of both arms over a 1-year period, developed febrile episodes and drowsiness with neck stiffness. Lumbar puncture revealed an increased protein content (161 mg/dL) and increased cell count (463/3) consisting of 99% of lymphocytes which contained atypical lymphocytes with multilobulated nuclei ('flower cells'), which are characteristic of ATL-L. Viral titers were positive only for HTLV-I antibodies (serum X 640: CSF X 16). Biopsy of an enlarged retroperitoneal lymph node revealed malignant lymphoma of the T-cell type. Brain MRI was negative, whereas an intradural extramedullary mass was found at the C4 level. With a diagnosis of ATL-L stage IV, chemotherapy was commenced, which was effective in reducing the generalized lymphadenopathy as well as the cervical mass and restoring the CSF findings to normality. The cervical cord mass was verified to be a solitary schwannoma, and ATL-L involvement was found not only in the leptomeninges, but also within the cervical cord schwannoma.
