Female, 30 years old, with headache, concern for viral meningitis. Brain parenchymal morphology is within normal limits. A punctate T2 hyperintense lesion is seen along the right lateral ventricle, and there may be one or two additional scattered punctate nonspecific white matter lesions. No evidence of parenchymal edema or mass effect is seen. No restricted diffusion is detected. There are no findings to suggest intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricular system is normal in size and morphology. Bone marrow signal characteristics are within normal limits. Mild mucosal inflammation is evident in the frontal sinuses and ethmoid air cells.
1. No definite acute intracranial abnormality or other specific findings to account for the patient's headaches, though please note that a normal imaging exam does not exclude the possibility of meningitis.2. Mild sinus mucosal inflammation.
