Intrathecal cytarabine (cytosine arabinoside) is included in many protocols for the treatment of acute lymphoblastic leukaemia of childhood. We report here the accidental administration of 200mg cytarabine intrathecally to a 4-year-old boy with CNS relapse. After the overdose the patient had dilated pupils during the first hour. One month later an unsteady gait and mild intention tremor in the hands were noted. By the exchange of cerebrospinal fluid with isotonic saline started 1 hour after overdose through a lumbar needle, about 27% of the administered dose was recovered. The estimated recovery in view of the time elapsed between overdose and start/end of the exchange procedure was 36%. This indicates that this procedure is of value in managing patients with heavy overdose of intrathecal cytarabine in hospitals without neurosurgical facilities.

A 4-y-old cat exhibited neurologic signs such as wobbling, right head tilt, and intention tremor, and MRI revealed a mass in the cerebellum. The cat died 5 mo after initial presentation, and no neoplastic lesions, other than the cerebellar mass, were observed at autopsy. Histologically, large atypical cells resembling Hodgkin cells, with single large inclusion-like nucleoli, and those resembling Reed-Sternberg cells, with symmetrically arranged nuclei, had infiltrated the left side of the cerebellum and were admixed with small lymphocytes. These atypical cells were positive for feline leukemia virus (FeLV), CD20, BLA36, vimentin, p16, p53, and Pax5, and negative for CD3, CD79a, and Iba1 by immunohistochemistry. Multiplex PCR for immunoglobulin heavy-chain gene rearrangement revealed monoclonal proliferation of B-lymphocytes. We describe this feline primary cerebellar B-cell lymphoma that displayed Hodgkin lymphoma-like tumor cells with FeLV protein expression.
