Dizziness and giddiness [R42], Reason for Study: ^Reason: Are there brain metastases? History: Hearing loss. Left sided ear fullness. Vertigo. Dysequilibrium. Metastatic cancer There is single restricted diffusion lesion on the left cerebellar hemisphere without evidence of hemorrhagic conversion (series 4, image 8) indicating acute ischemic infarction.Underlying brain shows non specific small vessel ischemic disease. There is no evidence of abnormal enhancement.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 mastoid air cells are clear.Mucosal thickenings on bilateral ethmoid sinuses, frontal sinus and left maxillary sinus.
1. Acute ischemic infarction on the left cerebellar hemisphere without evidence of hemorrhagic conversion.2. Non specific small vessel ischemic disease.3. No evidence of abnormal enhancement.
