Female, 18 years old, with history of recent cavernoma bleed with seizures. A bubbly heterogeneous lesion with T1 and T2 hyperintensity and strong susceptibility effect is demonstrated involving the right inferior postcentral gyrus and parietal operculum. The lesion measures up to 3 cm in diameter. The lesion causes mild local mass effect but there is no detectable edema in the surrounding brain parenchyma.The lesion itself enhances minimally if at all and there is no clear evidence of an associated developmental venous anomaly. No additional susceptibility inducing or enhancing lesions are identified.The remainder of the brain is within normal limits. No evidence of acute ischemia is seen. No evidence of significant parenchymal edema is detected. The ventricles are normal in size and morphology.
A 3 cm lesion is evident involving the right inferior postcentral gyrus and parietal operculum with imaging characteristics compatible with a cavernous malformation. No evidence of significant edema in the surrounding parenchyma is seen. No associated developmental venous anomaly is detected.
