45-year-old male with right-sided weakness. Evaluate for bleed, ischemia. Ill-defined area of low attenuation in the pons is new since prior study. The more well-defined focus of low attenuation in the right middle cerebellar peduncle was also not seen on prior study. Further evaluation with MRI is recommended if clinically warranted.Chronic infarct in the posterior limb of the left internal capsule involving the corona radiata is again seen. Nonspecific calcification in the pons has been seen since prior study from November 2009.There is no evidence of intracranial hemorrhage. The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. The visualized paranasal sinuses and mastoid air cells are normally pneumatized.
1. Ill-defined low attenuation in the pons is new since prior study. More well-defined focus of low attenuation in the right middle cerebellar peduncle was also not seen on prior study. Recommend evaluation with MRI if clinically needed.2. Old infarct in posterior limb of left internal capsule. No acute hemorrhage.
