53 years Male (DOB:8/29/1962)Reason: metastatic lung CA, followup to eval for brain mets History: nonePROVIDER/ATTENDING NAME: PHILIP C. HOFFMAN PHILIP C. HOFFMAN The CSF spaces are appropriate for the patient's stated age with no midline shift. There are is a FLAIR and T2 and diffusion-weighted imaging signal hyperintense focus in the right choroid plexus and the smaller one in the left choroid plexus. Most likely these represent xanthogranulomas.There is a 34 x 23 mm axial dimension cystic lesion in the anterior aspect of the left middle cranial fossa associated with remodeling of the adjacent bone. It follows spinal fluid on all pulse sequences.There are several periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. These are probably of little clinical significance. There are unchanged compared to the prior exam.No 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. There is intracranial origin of the left posterior inferior cerebellar artery.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.
1.There is no evidence for brain metastasis appreciated. 2.Arachnoid cyst in the left middle cranial fossa.3.Choroid plexus lesions most likely represent xanthogranulomas.
