Hemangioma of intracranial structures [D18.02], Reason for Study: ^Reason: 3T scanner, CCM protocol, QSM, permeability History: Known CCM yearly surveillance About 12.5 mm (measured on the axial T2 weighted image the longest diameter) sized right postcentral gyrus cavernous malformation is seen with the surrounding hemosiderin deposition unchanged since prior scan. On post Gad enhanced image, especially posterior aspect of the lesion shows some enhancement which is unchanged since prior scan. Punctate susceptibility lesion on the right thalamus is also seen, unchanged since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no edema, midline shift, intra or extra-axial fluid collection, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Right postcentral gyrus cavernous malformation is again seen, unchanged in terms of maximum diameter, MR characteristics and findings since prior scan.2. Susceptibility lesion on the right thalamus is again see, unchanged since prior scan.3. No evidence of acute ischemic or hemorrhagic lesion.
