Known cavernoma discovered on outside MRI in July, 2015. There is a subcentimeter lesion in the left parietal lobe with circumferential susceptibility effect and internal mixed T1 and T2 signal and apparent enhancement, compatible with a cavernous malformation. There is no evidence of surrounding edema to suggest acute hemorrhage. A faint linear area of enhancement just deep to the lesion may represent an associated developmental venous anomaly. No other focal lesions are identified. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or mass effect. There is no evidence of acute infarct. The orbits are unremarkable. There is a subcentimeter right maxillary sinus retention cyst.
Findings compatible with a subcentimeter cavernous malformation in the left parietal lobe, with a probable associated small developmental venous anomaly, but no evidence of acute hemorrhage.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
