78 years Male (DOB:1/4/1938)Reason: brain mass History: haPROVIDER/ATTENDING NAME: PETER C. WARNKE PETER C. WARNKE There is a heterogeneously enhancing mass involving the left periventricular white matter adjacent to the trigone the left lateral ventricle and extending to the left pre and postcentral gyri. It has heterogeneous signal characteristics on T2 with foci of low signal suggestive of blood products or calcifications. There is encasement of the trigone of the left lateral ventricle and adjacent body of the left lateral ventricle. Compared to the previous exam is relatively stable. Signal change extends into the left thalamus and left posterior limb of internal capsule.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions as well as lesions in the brainstem present identified on the FLAIR and T2 images.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The eyeball lenses are thin.
There is a partially calcified mass present in the left peritrigonal white matter extending to left pre and postcentral gyri and left thalamus. This appears stable compared to the prior exam. Please note that this exam was performed the purpose of stereotactic guidance during surgery and is limited.Periventricular and subcortical white matter lesions and lesions in the brainstem of a mild degree are nonspecific. At this age they are most likely vascular related.
