Sign and symptoms: Dizziness and dizziness abnormal findings on diagnostic imaging of head.Reason for study: Further evaluation of right periatrial hyperintensity, also rule out CP angle lesion.History: Vertigo, dizziness and weakness.. There is a T2/FLAIR hyperintense focus in the right periatrial white matter with corresponding T1 hypointense signal (image 18, series 701). This is second T2 hyperintense similar focus adjacent to the right frontal horn of the lateral ventricle (image 16, series 701). There is a third focus of T2 hyperintensity along the lateral aspect of the right splenium of corpus callosum (image 17, series 701), which was better appreciated on the prior MRI. None of these lesions demonstrates diffusion restriction, or susceptibility effects or abnormal enhancement. There is no evidence of intracranial hemorrhage or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation.Note that this study is not dedicated for internal auditory meatus /temporal bone. However, no abnormal enhancement in the cerebellar hemispheres or cerebello pontine angles are visualized. Bilateral internal auditory canals show no abnormal enhancement. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.There are three T2 hyperintense foci in the right periatrial, adjacent to the frontal horn of the lateral ventricle white matter and lateral aspect of the right splenium of corpus callosum. These foci particularly along the corpus callosum is suspicious for demyelinating lesions. Suggested detailed clinical examination as well as correlation with laboratory parameters.2.No evidence of posterior fossa or cerebellopontine angle tumor.
