Unspecified hearing loss, right ear [H91.91], Reason for Study: ^Reason: evaluate partially enhancing lesion from prior exam History: evaluate partially enhancing lesion from prior exam Redemonstration of multifocal variable sized ring-enhancing lesions on bilateral hemisphere with the susceptibility artifacts, unchanged since prior scan. There is no associated surrounding edema. Considering those lesions correspond to the CT findings of calcifications, differential diagnosis remained as neurocysticercosis, or other granulomatous infections. The ventricles, sulci and cisterns are unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. 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. Unchanged multiple bihemispheric ring enhancing nodular lesions without surrounding edema since prior scan.2. No evidence of new ischemic or hemorrhagic lesion.
