Hereditary hemorrhagic telangiectasia [I78.0] / Cerebral aneurysm, nonruptured [I67.1], Reason for Study: ^Reason: 3T scanner, please evaluate for AVMs, HHT, and evaluate known aneurysm (please compare to outside images uploaded to PACS) Brain MRINo evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear. There is a retention cyst on the right maxillary sinus.Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate left Pcom origin infundibulum which demonstrated patent left Pcom artery and smooth luminal bulge at the right Pcom area. The bulge at the right Pcom area is measured about 0.8mm x 2.6mm which most likely represent right Pcom infundibulum. Comparing to prior scan performed at outside hospital, there is no significant interval change.Otherwise bilateral ICAs, MCAs and ACAs appear to be normal. Vertebrobasilar system appears to be normal.
1. No evidence of abnormal enhancement. No acute ischemic or hemorrhagic lesion.2. Right Pcom area luminal bulging most likely represent infundibulum, the left pcom origin infundibulum. No change since prior scan.3. No evidence of intracranial arterial aneurysm. No evidence of unusual vascularity or evidence of arteriovenous shunt.
