Status post right frontal craniotomy and mass resection. Again seen are expected postoperative changes related to right frontal craniotomy and mass resection, including pneumocephalus, a small amount of hemorrhage, and persistent vasogenic edema. There is a rim of restricted diffusion in the resection cavity, compatible with cytotoxic edema. There is persistent mild leftward midline shift and partial effacement of the right lateral ventricle, similar to recent CT. No uncal herniation.There is no definite evidence of residual tumor. However, there is minimal residual enhancement which is questioned along the medial aspect of the resection cavity.Normal vascular flow voids are present in the major intracranial vessels. The visualized portions of the paranasal sinuses and mastoid air cells are clear. The visualized portions of the orbits are intact. The eyeball lenses are thin.
1.Status post right frontal craniotomy and right frontal lobe mass resection with expected postsurgical changes, including a small amount of hemorrhage in the resection cavity. 2.Persistent vasogenic edema, regional mass effect, and mild leftward midline shift, not significantly changed from recent CT. 3.No definite evidence of residual tumor. There is question of minimal residual enhancement along the medial aspect of the resection cavity, which can be further assessed on follow-up imaging.
