Altered mental status, unspecified [R41.82], Reason for Study: ^Reason: assess for structural lesion History: memory difficulties There is no evidence of acute ischemic or hemorrhagic lesion.There is no evidence of abnormal enhancement.Small developmental venous anomaly is seen on the left parietotemporal lobe white matter (trigone area).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, 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 paranasal sinuses and mastoid air cells are clear.
1. No evidence of acute ischemic or hemorrhagic lesion.2. No evidence of abnormal enhancement.3. Developmental venous anomaly on the left posterior parietotemporal area white matter.
