Female, 52 years old, with headache. A 5 mm lesion is redemonstrated within the right occipital lobe showing internal T2 hyperintensity and a rim of surrounding susceptibility effect. The lesion has not changed in size. The surrounding parenchyma is free of edema. Adjacent curvilinear enhancement most likely represents a developmental venous anomaly.Several scattered small foci of nonspecific FLAIR hyperintensity are redemonstrated within the cerebral hemispheres showing no significant interval change. No edema or mass effect is detected. No abnormal extra-axial fluid collections are seen and there is no evidence to suggest acute intracranial hemorrhage. Ventricular size and morphology are within normal limits. No additional pathologic enhancement is identified intracranially.
1.Stable presumed right occipital cavernous malformation with an associated developmental venous anomaly.2.Stable scattered foci of nonspecific signal abnormality.3.No new or additional findings are seen to account for the patient's symptoms.
