Anoxic brain damage, not elsewhere classified [G93.1] / Extrapyramidal and movement disorder, unspecified [G25.9], Reason for Study: ^Reason: f/u MRI, anoxic brain injury History: 12 yr F with anoxic brain injury secondary to hanging There is no evidence of acute ischemic or hemorrhagic lesion on this scan.Previously seen bilateral basal ganglia restricted diffusion are not demonstrated anymore on today's scan.On T2/FLAIR images, posterior aspect of basal ganglia which showed diffusion restriction on prior scan now shows almost normalized.The most prominent difference of this scan from prior scan is global brain volume loss. Bilateral supra and infra tentorial brain parenchyme show more prominent sulci and slightly increased ventricular system. 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. Mucosal thickening on ethmoid sinuses.Bilateral mastoid air cells show opacifications.
1. Interval resolution of bilateral posterior basal ganglia restricted diffusion lesions on today's scan.2. No evidence of acute ischemic or hemorrhagic lesion.3. Diffuse volume loss on bilateral supra and infra tentorial brain parenchyme comparing to prior scan.
