A case of central nervous system (CNS) leukemia with normal bone marrow, associated with a novel chromosomal abnormality, is described. A 58 year-old woman complained of hearing disturbance, severe headache and vomiting, and showed signs of meningeal irritation, as well as papilledema and bilateral dysacusis. Immature atypical cells were found in the cerebrospinal fluid (CSF) with elevated pressure, pleocytosis, increased protein and decreased glucose levels. She was diagnosed as having neoplastic meningitis. In spite of intensive investigations, including bone marrow puncture, malignancies were not found in organs other than intra-cranial site. The symptoms and CSF findings were temporarily improved with chemotherapy and irradiation, but she relapsed into neoplastic meningitis. The anaplastic cells in CSF were positive with CD45 by immunocytochemistry, and were positive by peroxidase staining. Thus, the anaplastic cells were considered to be myelocytic leukemic cells. Chromosomal analysis showed that these leukemic cells had a novel chromosomal abnormality: 46XX, 4q+, 10q-, 16q-. There has been no report of leukemic meningitis without bone marrow abnormalities. It is possible that this peculiar abnormal chromosome is related to the primary infiltration of the central nervous system. With this novel chromosomal abnormality, this case is important for considering the mechanism of primary leukemic meningitis.
BACKGROUND: Neurological involvement is a significant cause of morbidity and mortality in patients with sarcoidosis. Detection and management of neurosarcoidosis remains problematic. Our interest in immunosuppressive agents for chronic sarcoidosis has given us experience with various agents for the treatment of sarcoidosis, including cyclophosphamide and methotrexate. METHODS: We analyzed all patients with sarcoidosis seen in our clinic during a 10-year period. Evaluation for neurological disease included routine physical examination. Magnetic resonance imaging, cerebral spinal fluid analysis, and neural tissue biopsy were performed where clinically indicated. Patients were treated with corticosteroids, methotrexate, or cyclophosphamide. RESULTS: Neurological disease was identified in 71 of 554 patients with sarcoidosis. Seventh (facial) cranial nerve paralysis was the most common manifestation identified in 39 patients. This included 24 patients with facial nerve palsy as the only manifestation of neurological sarcoidosis in whom complete recovery was seen in all but 1 patient. Forty-eight patients with disease other than facial nerve palsy received corticosteroids or other therapies. Corticosteroids benefited only 14 patients (29%). Methotrexate successfully treated 17 (61%) of 28 patients and cyclophosphamide controlled disease in 9 (90%) of 10 assessable patients. Methotrexate and cyclophosphamide were each associated with a higher response rate than corticosteroids alone (chi 2, 14.6; P < .001). CONCLUSIONS: Neurological symptoms can be significant manifestations of sarcoidosis. Facial nerve paralysis is a common, but usually self-limited form of disease. Other manifestations are usually chronic and agents other than corticosteroids appear to have increased efficacy with lower morbidity.
