Left frontal hemorrhage. The images are markedly degraded by patient motion.MRI: There is predominantly T1 and T2 high signal extensive hemorrhage in the anterior left frontal lobe with peripheral susceptibility effect and surrounding vasogenic edema. The hematomas collectively measures up to approximately 6 x 4 cm in axial cross-section. There is effacement of the anterior portions of the lateral ventricles and 8 mm of midline shift to the left. There is no evidence of acute infarct. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA: There is no gross intracranial arterial anomaly, within the limits of motion artifact. MRV: There appears to be hypoplasia of the left transverse sinus. The other major cerebral venous sinuses are grossly intact, within the limits of motion artifact.
Subacute left frontal lobe intraparenchymal hemorrhage with surrounding vasogenic edema. No gross cerebral artery or venous abnormalities are apparent, although the images are markedly degraded by patient motion. Consequently, CTA and CTV may be considered for further evaluation.
