Pre B-ALL, admitted for neutropenic fever with no current source of infection identified. Has headaches and concern for possible meningitis. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is mild diffuse cerebral white matter T2 hyperintensity. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift. The cerebellar tonsils are perhaps slightly low-lying, but do not have pointed morphologies. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
No evidence of intracranial abscess, mass, or acute infarct. Mild diffuse cerebral white matter T2 hyperintensity may be treatment-related.
