Female, 65 years old, status post craniotomy for tumor resection. Since the prior examination, craniotomy has been performed at the high vertex. The previously seen enhancing tumor centered on the interhemispheric falx has been partially resected. It appears that all of the tumor to the left of the falx, and a majority of the tumor to the right of the falx, has been resected. Ill-defined enhancement along the left aspect of the resection cavity is nonspecific and could be related to surgical change. Thicker enhancement along the right aspect of the resection cavity likely reflects residual tumor.Vasogenic edema within the bilateral superior frontal gyri around the resection bed appears unchanged when compared to the immediate prior examination. No new areas of parenchymal edema are observed.Evidence of a prior large left frontal craniotomy are again seen. A resection cavity within the left middle frontal gyrus is unchanged. No abnormal enhancement is seen at this operative site to suggest recurrent tumor.An 8 mm extra-axial enhancing lesion along the dura overlying the left superior temporal gyrus is unchanged. A small area of enhancement within the left squamous temporal bone is unchanged and may represent a nonspecific osseous lesion or burr hole defect. No additional enhancing lesions are seen. No new areas of pathologic parenchymal signal abnormality are detected. The ventricular system is stable in size and morphology.
1.Expected postoperative findings status post craniotomy for resection of a falcine meningioma. Most of the lesion has been resected with only a small amount of suspected residual tumor along the right aspect of the resection margin. Associated vasogenic edema within the adjacent superior frontal gyri is unchanged.2.Evidence of prior left frontal tumor resection is redemonstrated without significant interval change. A small presumed meningioma overlying the left superior temporal gyrus is unchanged.
