 MRI BRAIN: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is minimal periventricular white matter T2 hyperintensity. The brain parenchyma otherwise appears unremarkable. There is no abnormal intracranial enhancement. The ventricles and sulci are borderline prominent. There is no midline shift or herniation. The major cerebral flow voids are intact. There are retention cysts in the sphenoid sinuses. The skull and scalp soft tissues are unremarkable. There is a partially-imaged cystic lesion in the right maxillary alveolus.MRA HEAD: There is no evidence of significant steno-occlusive lesions or aneurysms, within the limits of MRA.MRV HEAD: The left transverse and sigmoid sinuses and internal jugular vein are hypoplastic. However, there is no evidence of venous thrombosis.
1. No evidence of intracranial mass or acute infarction.2. No evidence of flow-limiting stenosis or aneurysm.3. No evidence of venous sinus thrombosis.4. Partially-imaged cystic lesion in the right maxillary alveolus may represent a radicular cyst or globulomaxillary cyst, for example. Dedicated maxillofacial imaging may be useful for further evaluation, if clinically warranted.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
