Clinical question: Preop planning study. Signs and symptoms: Brain tumor. Preoperative planning study. Pre- and post enhanced Stealth brain MRI:Examination is performed utilizing surgical planning protocol and is not a true complete diagnostic study.Examination redemonstrates a partially solid and cystic enhancing intra-axial in the right anterior and mid temporal lobe. The well-demarcated superficial solid component of the mass demonstrate inhomogeneous enhancement and measuring maximum of 19 x 38 x 44 mm in size. Immediately medial to the solid component of the mass there is a large minimally septated cystic and nonenhancing component measuring at least at 47 x 40 mm in transaxial dimensions. There is resultant significant mass effect on the temporal horn of lateral ventricle. Posteriorly the mass reaches the trigone of right lateral ventricle and with bulge of the cystic component of tumor into the right trigone of the lateral ventricle which is best appreciated on prior noncontrast study. There is also subtle mass effect on the right lateral ventricle however without evaluation of midline and widely patent basal cisternsA punctate focus of enhancement noncontiguous with the tumor in the right temporal lobe (axial post enhanced series 501 image 103 coronal post enhanced series 701 image 20. Images through posterior fossa on post enhanced series demonstrate a multi branch vascular enhancement in the right cerebellum consistent with a developmental venous anomaly
1.Partially solid and enhancing with a large nonenhancing cystic component mass in the right anterior and mid temporal lobe as detailed above.2.There is bulge of the cystic component of tumor into the trigone of right lateral ventricle as detailed.3.Small developmental venous anomaly in the right cerebellum as detailed.4.A noncontiguous punctate focus of enhancement immediately anterior to the mass in the right anterior temporal lobe as mentioned.
