Malignant neoplasm of brain, unspecified [C71.9], Reason for Study: ^Reason: 42 yo M with hx of L frontal PXA s/p surgery then RT, eval for progression/recurrence History: none The examination is limited by motion artifact. Postsurgical changes with multiple left frontal bone burr holes are again demonstrated. The left frontal lobe resection cavity appears similar to prior examination with a small amount of surrounding T2/FLAIR signal. The head of the caudate is atrophic and has intrinsic high T1 signal, without significant enhancement, likely postoperative in etiology. Small area of enhancement involving the inferomedial aspect of the cavity (series 11, image 17) appears similar to prior examinations. No new or enlarging enhancing lesions are identified. No midline shift is appreciated. There is no evidence for acute ischemia. Blood degradation products are again demonstrated in the left frontal lobe subarachnoid space and surgical resection cavity. No new areas of hemorrhage are identified. Scattered areas of T2/FLAIR hyperintensity, more prominent in the left cerebral hemisphere are again seen. Prominent vascularity versus leptomeningeal enhancement involving the middle left frontal lobe gyrus appears similar to prior examination.
Postsurgical changes related to left frontal lobe mass resection without evidence for tumor progression. A small nonspecific focus of enhancement at the surgical site remains similar to prior examinations.
