Clinical question: Status post biopsy. Signs and symptoms: Status post biopsy. Pre and post enhanced brain Stealth MRI:Examination demonstrates a thin rim enhancing lesion in the anterior and mid temporal lobe lateral to the trigone of left lateral ventricle. It measures approximately 25 mm in AP axis and 8mm in transverse. No significant change since prior exam.Extensive surrounding FLAIR and T2 hyperintensity without enhancement is again also noted suspected of nonenhancing component of tumor. There are thin serpiginous low T2 signal intensity consistent with previously seen cortical calcification on prior CT is again noted without change. Beyond this region vasogenic edema anterior and posterior to the mass similar to prior exam is again noted. Findings resulting regional mass effect as well as trace the radiation of midline to the right without significant change since prior exam. A small linear and loculated internal focus of T2 hyperintensity suggestive of track of prior biopsy approach.Stable normal size of ventricular system.No detectable new foci of signal abnormality or abnormal parenchymal/leptomeningeal enhancement.There is however new thin uniform dural thickening and enhancement in the left temporal and frontal region likely as result of recent surgical intervention.
1.Revisualization of partially enhancing mass in the left anterior and mid temporal lobe without significant change since prebiopsy study. Stable regional mass effect and trace deviation of midline to the right.2.Expected post biopsy changes and including mild uniform dural thickening and enhancement in the left frontal and temporal region.
