60 years Male (DOB:3/9/1956)Reason: hx brain cyst by CT. Eval cyst or abnormality History: none- surveillance post CTPROVIDER/ATTENDING NAME: BAKHTIAR YAMINI BAKHTIAR YAMINI The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. There is a cystic lesion present within the posterior aspect of the lumen are positive. This splays the internal cerebral veins and displaced the vein of Galen. It measures approximately 21 x 23 x 22 mm in size. It follows spinal fluid on all pulse sequences including diffusion. There is no associated contrast enhancement. This was also present on the CT from 8/16/2016 and is unchanged in sizeNo abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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 demonstrate a mucous retention cyst along the superior aspect of the left maxillary sinus. This mucous retention cyst is associated with hyperdense appearance on CT and a central hypointense appearance on T2 with a mildly hyperintense appearance on T1. This most likely represents some inspissated secretions.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Arachnoid cyst within the velum interpositum.2.Periventricular and subcortical white matter lesions of a mild degree are nonspecific. At this age they are most likely vascular related.
