seizure, R frontal contusions vs AVM vs mass. The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a somewhat lobular appearing mass present centered in the lateral aspect of the left orbital gyrus adjacent to the left inferior frontal gyrus measuring 20 x 12 mm axial dimensions which has a surrounding low signal rim on T2 and FLAIR MRI and blooming on susceptibility weighted imaging. Centrally it is high signal on T1 and T2 and FLAIR. In general has a popcorn-like appearance.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate air-fluid levels in the maxillary sinuses and scattered opacities in the ethmoid air cells with air-fluid levels in the sphenoid sinuses. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a left frontal lobe lesion present which is suspicious for a cerebral cavernous malformation with recent hemorrhage based on its imaging characteristics.2.Opacification of the paranasal sinuses and nasal cavity. There is suspicion for acute sinusitis. Please correlate with clinical symptoms and history.
