Hi doctors. i'm having a ct scan of the sinuses. the mri of the brain from december, 2020 found opacification, but no tumor, nor did a visual endoscopy of my sinuses in the office....is it likely that there still may be tumors found on the ct scan?

No, appears likely that any neoplastic lesions have been excluded. But if you still have misgivings, you could consider a virtual consult on the paid portion of our site (www.connect@healthtap.com). Also, if not done yet, have an otolaryngologist manage your issues. CAT scan may reveal polyps but doubt a tumor per se.

Hello, a sinus opacification may suggest polyps, a fungal infection and possibly a wart like lesion called inverting papilloma. A nasal endoscopy may not show anything. Inside the sinus, fluid or trapped mucus could cause the opacification but also could any soft tissue including a tumor. See your ENT doctor for a complete evaluation and treatment.
