- Background: Children with central nervous system (CNS) toxicity during therapy for acute lymphoblastic leukaemia (ALL) are at risk for treatment modifications, long-term sequelae and even higher mortality. A better understanding of CNS symptoms and their complications improves the potential to prevent and treat them.Methods: Patient files from 649 children treated with Nordic Society of Pediatric Hematology and Oncology ALL92 and ALL2000 protocols in Finland were reviewed retrospectively for any acute CNS symptom. Detailed data on symptoms, examinations and treatment of the underlying CNS complications were collected from the medical records. Disease-related and outcome data were retrieved from the Nordic leukaemia registry.Results: Altogether, 13% (86) of patients with ALL had acute CNS symptoms. Most symptoms (64%) occurred during the first 2 months of therapy. Posterior reversible encephalopathy syndrome was the most frequent complication (4.5%). Cerebrovascular events were diagnosed in 10 cases (1.6%), while methotrexate-related stroke-like syndrome (SLS) was observed in only one patient (0.2%). CNS symptoms due to systemic or unclear conditions, especially sepsis, were important for differential diagnosis. CNS leukaemia was associated with CNS symptoms (hazard ratio [HR] = 4.03; P = .003), and epilepsy was a common sequel of CNS complications (19%).Conclusions: Acute CNS symptoms are common during ALL therapy, occurring mainly during the first 2 months of treatment. Patients with CNS leukaemia at diagnosis are at a higher risk for CNS toxicity. Despite intensive CNS-directed methotrexate treatment, SLS was diagnosed extremely rarely in our series.

- Central nervous system (CNS) involvement in childhood acute myeloid leukemia (AML) can manifest as leukemic cells in the cerebrospinal fluid, a solid CNS tumor, or as neurological symptoms. We evaluated the presenting symptoms and neuroimaging findings in 33 of 34 children with AML and CNS involvement at diagnosis in the period 2000-2012 in Sweden, Finland, and Denmark. Imaging was performed in 22 patients, of whom 16 had CNS-related symptoms. Seven patients, including all but two with facial palsy, had mastoid cell opacification, considered an incidental finding. The frequent involvement of the mastoid bone with facial palsy warrants evaluation in larger series.
