disturbance of skin sensation There is 13mm x 9mm x 5mm sized lesion with ectatic venous structure indicating arteriovenous malformation on the left middle posterior temporal gyrus possibly within the left lateral occipital sulcus. There is no associated hemorrhage or surrounding edema.No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or 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.3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate enlarged left MCA angular branch with vascular blushing on the left temporo occipital lobe area indicating AVM.Otherwise unremarkable brain MRA.
Possible left temporo-occipital AVM without evidence of hemorrhage or surrounding edema supplied from the left MCA angular artery.
