46-year-old female with cerebral cavernous malformation, annual surveillance. Please note the patient declined the research scan portions of the study. Artifact from a right frontal approach ventriculostomy catheter somewhat obscures adjacent structures.There is redemonstration of a cerebral cavernous malformation in the right paramedian quadrigeminal plate, again measuring approximately 9 x 9 x 9 mm, without significant appreciable change. Surrounding hemosiderin laden parenchyma is stable, and there is no perilesional edema. As before, there is very subtle mass effect on the aqueduct without change. There is revisualization of a previously seen associated developmental venous anomaly with recruitment of the left perimesencephalic and basal vein of Rosenthal which is stable in appearance. There are no MR findings of other similar appearing foci.There is no restricted diffusion to suggest acute ischemia. A right frontal approach ventriculostomy catheter is present with the tip projecting into the basilar cistern, unchanged. The ventricles are stable in size and configuration. There is revisualization of a stable small right frontal developmental venous anomaly. There are a few punctate nonspecific foci of increased T2 hyperintensity in bilateral frontal lobes which appear unchanged. There is minimal gliosis along the right frontal approach ventricular catheter, unchanged. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.No significant interval change in appearance of right paramedian quadrigeminal plate cavernoma and its associative developmental venous anomaly.2.Shunted ventricles stable in size and configuration.
