51-year-old female status post craniotomy for tumor resection. Presents for surveillance. Redemonstration of a right parietal craniotomy status post resection of a lesion from the right precentral gyrus. A small somewhat ill-defined focus of enhancement along the precentral gyrus appears similar to the preoperative examination. T2 hyperintensity within the gyrus is unchanged.Evidence of additional previous surgery includes a right pterional craniotomy and multiple surgical/aneurysm clips along the right sphenoid wing, multiple bilateral burr holes and placement of a posterior fossa drainage catheter. The loculated appearing subdural collection seen along the right parietal lobe on the prior examination has completely or near completely resolved. Bilateral frontal subdural collections are not significantly changed. Bilateral diffuse dural thickening and enhancement is unchanged.The previously demonstrated shunted lesion within the medial left cerebellum shows no significant interval change. As before, this lesion contains an enhancing focus which measures up to 12 mm in diameter. A nonenhancing area of T2 signal abnormality within the left middle frontal gyrus is unchanged. Scattered nonspecific foci of T2 hyperintensity are seen within the cerebral hemispheres, nonspecific but unchanged. The ventricles are stable in size and morphology.
1.Postsurgical findings are seen compatible with lesion resection from the right precentral gyrus. A small nodule of enhancement and associated T2 signal abnormality at this site appears similar to the preoperative study.2.Evidence of more remote surgical intervention is again seen including aneurysm clipping along the right sphenoid wing and placement of a drainage catheter through the left cerebellum.3.An enhancing lesion within the left medial cerebellum and a nonenhancing lesion within the left middle frontal gyrus are unchanged. No new intracranial lesions are demonstrated.4.A somewhat loculated subdural collection seen previously along the right parietal lobe has significantly improved. Bilateral frontal subdural collections are unchanged.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
