Female 13 years old with Li Fraumeni syndrome, routine screening. Exam is mildly motion degraded. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is an area of susceptibility artifact within the right posterior occipital lobe suggestive of a dural venous anomaly. No associated brain edema noted. The brain parenchyma and pituitary gland otherwise appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. Trace bilateral maxillary mucosal thickening and mild opacification of the mastoid air cells is noted. The orbits, skull, and scalp soft tissues are grossly unremarkable.
