This report describes a case in which diplopia was developed as a finding of postinfectious anti- N -methyl- d -aspartate receptor encephalitis. Infectious encephalitis, especially herpes simplex virus, is essential as it is one of the triggers of autoimmune encephalitis. Even if the cases present unexpected clinical findings, we should be vigilant in terms of autoimmune processes, such as diplopia seen in our case.

Acute leukemia in children may present with hyperleukocytosis. Symptomatic hyperleukocytosis is a medical emergency that necessitates rapid stabilization of the patient and prompt lowering of the leukocyte count. We report on a patient with intracranial hemorrhage associated with T-cell acute lymphoblastic leukemia with hyperleukocytosis, which is a rare occurrence. A 16-year-old boy with hyperleukocytosis (total white cell count; 398×103/µL) underwent repeated leukapheresis and received supportive treatment until a definite diagnosis of T-cell acute lymphoblastic leukemia was made and chemotherapy was started at 10% of the usual dose. On day 2 of treatment, he had headache, vomiting, and was agitated. Brain magnetic resonance imaging showed bilateral extensive hemispheric and cerebellar punctate areas of hemorrhage and perilesional edema. Chemotherapy intensified to a maximum dose on day 3. If supportive care for tumor lysis syndrome can be promptly provided, initial chemotherapy regimen can immediately be begun at an optimal dose.
