Female, 46 years old, with known right parietal cavernoma with DVA, clinical presentation of seizures. An 8 x 7 mm lesion is evident within the right parietal white matter demonstrating bubbly internal T2 bright signal and a rim of susceptibility. Associated with this lesion, there is a small developmental venous anomaly which drains to the right thalamostriate system.A small developmental venous anomaly is evident within the posterior left frontal white matter. No other definite pathologic or anomalous enhancement is seen. Mild susceptibility effect is evident within the posterior aspect of the right superior frontal sulcus and along the right calcarine fissure.A prominent perivascular space is evident along the right anterior commissure. No other areas of significant parenchymal signal abnormality are detected. No abnormal extra-axial collections are noted. The ventricular system is within normal limits for size and morphology. Incidental note is made of bilateral choroid plexus cysts.
1.A lesion in the right parietal white matter is seen compatible with a cerebral cavernous malformation with associated developmental venous anomaly.2.A small developmental venous anomaly is also evident within the left posterior frontal white matter.3.Hemosiderin staining along the posterior aspect of the right superior frontal sulcus, and along the right calcarine fissure, would suggest the sequelae of a prior hemorrhagic event.
