I had undergone gamma knife radiosurgery on 2017 for choroidal plexus avm in the right temporal horn in lateral ventricle. Doctors asked to follow up at 6 months interval. In all previous scans, doctors said that there are good recovery and gliosis. How long will it take for avm to shrink completely? In the recent MRI has taken yesterday, it was said that findings: there is focal t2w high signal area is seen at the right superior temporal/transverse temporal gyrus region. This area shows low signal on gre images - located close to the ependymal margin of temporal horn. Following contrast, multiple tortuous vessels were seen in this region along the gyri, reaching the Sylvian fissure. One of the arterial feeders appears to be the branch from the choroidal artery from the temporal horn of right lateral ventricle. 15 x 5 mm mm are of tortuous vessels (post-contrast thin section t1fs) the venous drainage reaches the vein of life/superficial middle cerebral vein and joins the right transverse sinus. There is also another parietal cortical vein reaching the sss minimal gliotic signal around the right trigonal white matter, seen close to Sylvian fissure. brain stem appears normal. The cerebellar hemispheres appear normal. the third and left lateral ventricles appear normal. sella and parasellar region are normal. Visualized orbits and sinuses appear normal. craniovertebral junction and cervicomedullary junction appear within normal limits. Impressions: features suggestive of right temporal focal av malformation with feeding vessel and draining vein as described above. the dural component is more prominent with short tortuous prominent vessels minimal gliosis present. Please explain to me about the report. How long will it take for a complete cure? Waiting for your answer.
