Sinonasal basaloid carcinoma that was resected. Planning for chemo/RT. There are interval postoperative findings related to interval resection of a sinonasal mass with a subcentimeter nodular lesion in the region of the olfactory recesses. There is slight extension of the tumor into the epidural space of the anterior cranial fossa via defects in portions of the ethmoid roof. There are residual secretions and mucosal thickening within the left maxillary sinus, left ethmoid cavity, and sphenoid sinuses. 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 interval resection of a sinonasal mass with a subcentimeter nodular lesion in the region of the olfactory recesses that appears to have slight epidural extension along the floor of the anterior cranial fossa, which is suggestive of 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.
