Female, 39 years old, with dizziness, nystagmus, nausea and vomiting. Evaluate for vestibular etiology of symptoms. A small curvilinear focus of subcortical FLAIR hyperintensity is demonstrated within the precuneus of the right parietal lobe. Several additional scattered punctate foci of white matter are also seen.No evidence of edema or mass effect is detected. No restricted diffusion is seen. A small ill-defined focus of enhancement is present within the cerebellum at the level of the fastigial point which is favored to represent a small vascular anomaly such as a DVA or telangiectasia. No definite pathologic parenchymal enhancement is observed.No evidence is seen to suggest acute or chronic intracranial hemorrhage. There are no abnormal extra axial fluid collections. Ventricular size and morphology are within normal limits.The fluid-filled structures of the inner ear demonstrate normal morphology and signal characteristics. The cranial nerve 7/8 complex is within normal limits. No pathologic enhancement is seen within the IACs or CP angles.
1.Scattered small foci of FLAIR hyperintensity are demonstrated within the cerebral white matter, one of which is relatively curvilinear and subcortical location. These lesions are nonspecific, though the distribution and morphology raise the possibility of a demyelinating process. An inflammatory or vasculitic process could also be considered.2.Unremarkable evaluation of the IACs.
