Assess for possible left parieto-occiptal cavernoma: unusual sensory symptoms-water running on right side of head, balance issues. There is a non-enhancing subcentimeter lesion with peripheral susceptibility effect in the right lateral parieto-occipital region and an associated right periatrial developmental venous anomaly. There is no surrounding vasogenic edema. There are unchanged mild scattered punctate foci of nonspecific T2 hyperintensity in the cerebral white matter. There is no evidence of intracranial hemorrhage or acute infarct. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There is moderate mucosal thickening in the left sphenoid sinus. The skull and extracranial soft tissues are unremarkable.
Unchanged subcentimeter right parieto-occipital region cavernous malformation and an associated developmental venous anomaly.
