Sudden visual loss There is restricted diffusion area on the left temporal occipital lobe without evidence of hemorrhage transformation. This lesion indicates acute ischemic infarct.On FLAIR imaging, there is a focal tissue loss on the right frontal lobe middle frontal gyrus and left side pons indicate possible chronic ischemic infarction. High signal intensity on the right insular subcortical white matter on FLAIR images also indicates chronic ischemic lacunae.In addition, there are multiple scattered high signal intensities on centrum semiovale and periventricular white matter indicate nonspecific small vessel ischemic disease.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, midline shift, intra or extra-axial fluid collection/hemorrhage, 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.There is a 9.5 mm sized relatively well circumscribed cystic lesion on the posterior pharyngeal mucosa in between longus coli muscle indicate Thornwaldt's cyst.
1. Acute ischemic infarction without hemorrhagic transformation on the left temporo-occipital lobe.2. Multi focal chronic ischemic infarctions with underlying non specific small vessel disease.
