Unspecified foreign body in respiratory tract, part unspecified causing other injury, initial encounter [T17.908A], Reason for Study: ^Reason: Clinical concern for aspiration for unknown reason, assess for prior CVA History: aspiration There is no evidence of acute ischemic lesion on the scan.Multifocal scattered susceptibility lesions without associated with surrounding edema or mass effect on both supra and infratentorial brain parenchyma indicate chronic petechial hemorrhage or calcification.Scattered FLAIR/T2 high signal intensity lesions on bilateral periventricular white matter and centrum semiovale are nonspecific, most likely represent nonspecific small vessel ischemic disease.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 mastoid air cells are clear. Bilateral maxillary sinuses appear to be small with the minimal cortical thickening.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Minimal nonspecific small vessel ischemic disease.3. Multifocal susceptibility lesions are nonspecific, diagnostic possibilities include multiple parenchymal chronic hemorrhage or calcification.
