There is a dural based lesion along the posterior falx cerebri that measures up to 3 mm in width, which is unchanged. There is diffuse cerebral volume loss. There are bilateral lens implants and staphylomatous deformity of the globes. There is no evidence of tumor extension into the orbits.
1. Postoperative findings related to resection of a sinonasal mass with an unchanged subcentimeter lesion in the region of the olfactory recesses that appears to have slight epidural extension along the floor of the anterior cranial fossa, which may represent residual tumor.2. A dural based lesion along the posterior falx cerebri that measures up to 3 mm in width is unchanged and may represent a meningioma.
