Left parietal progressive glioblastoma and history of facial soft tissue rhabdomyosarcoma. There are postoperative findings related to left parietal craniotomy. There has been interval increase enhancing component of the tumor with a residual focus of nodular enhancement that measures up to 12 x 17 mm in the axial plane along the medial aspect of the resection cavity. Diffuse linear enhancement along much of the posterior margins of the resection cavity and the surrounding confluent T2 hyperintensity appear stable to slightly more prominent. Furthermore, there is interval increase in size of an enhancing extra-axial lesion along the left lateral temporal lobe convexity, which measures 14 x 16 mm in the axial plane. There is an unchanged anterior left middle cranial fossa arachnoid cyst. There is no significant midline shift. There is no evidence of acute territorial infarction. There is right tympanomastoid fluid. The regional extracranial structures are unchanged.
1. Findings suggestive of interval tumor progression in the left parietal lobe region treatment bed.2. Interval increase in size of the extra-axial lesion, which may represent a radiation-induced meningioma
