 There are postoperative findings related to left frontoparietal craniotomy for resection of left frontal lobe mass. There is a susceptibility effect within and along the margins of the left frontal lobe cavity with near total resection of the mass and a nonspecific subcentimeter focus of enhancement along the medial aspect of the surgical cavity in the left frontal lobe. There is a left extra-axial postsurgical fluid collection measuring 4 mm in thickness with mild thickening and enhancement of the dura subjacent to the craniotomy, along with a left scalp fluid collection with blood products and mild to moderate swelling of the superficial left facial, periorbital and scalp soft tissues. Apparent restricted diffusion along the margins of the surgical cavity may be related to hemorrhage or ischemic tissue. There is no evidence of territorial infarction, however. There are unchanged heterogeneously enhancing masses with extensive vasogenic edema in the right frontal lobe. There is no significant midline shift or herniation. There are bilateral maxillary sinus mucus retention cysts.
1. Postoperative findings related to left frontal lobe metastasis resection with nonspecific subcentimeter foci of enhancement along the medial aspect of the resection cavity, which may represent residual tumor or granulation tissue, and extensive residual left frontal lobe vasogenic edema.2. Unchanged metastases un the right frontal lobe with extensive surrounding vasogenic edema, but no significant midline shift.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
