From 1991 to 1995, we reviewed the medical records of 200 pediatric patients with systemic malignancies to study the occurrence of neurologic complications and their treatment. A total of 25 patients with neurologic complications were found. Complications included intracranial metastasis (one patient), intraspinal metastasis (one), spinal epidural compressions (three), leptomeningeal metastases (six), metabolic encephalopathy (10), opportunistic infection (one), cerebrovascular disorders (three), treatment complications (six) and paraneoplastic syndromes (two). Ten patients had seizures. One patient with acute lymphoblastic leukemia (ALL) had the unusual complication of cytomegalovirus retinitis and glaucoma. Seven patients had neurologic features at presentation. ALL was the most common malignancy (56%) and neuroblastoma (20%) was the second. Neurologic deficits are frequently seen in pediatric patients with systemic malignancies and can, in fact, be the presenting signs. Early diagnosis and treatment is important to prevent further neurologic disability.

We describe the case of a 16-month-old girl with neuroblastoma and chronic lymphocytopenia due to chemotherapy and treosulfan-containing megatherapy who developed cytomegalovirus retinitis and neuritis. Intravenous ganciclovir and anti-cytomegalovirus immunoglobulin were used with a transient benefit; however, retrobulbar gancyclovir resulted in a complete remission. This report emphasizes the need for close monitoring of viral infections in patients undergoing treosulfan-containing megatherapy, highlighting the immunosuppressive effects of this agent, and indicates the potential use of retrobulbar ganciclovir as the alternative method of drug delivery.
