Can you interpret MRI reports post pituitary macroadenoma surgery?

Hello doctor,

This query is regarding my husband's health. Three months back, my husband underwent surgery for pituitary macroadenoma. He was advised Hisone steroid tablet for three months. But he has a headache on and off. He has gained 19.8 lbs in three months, though he eats very little. Yesterday, we took the third month follow up MRI (Magnetic Resonance Imaging) scan and I wanted to share below findings in the MRI report. Post-operative changes noted in sphenoid sinus and sellar fossa. Pituitary stalk mildly deviated to the left side. No evidence of enhancing residual and recurrent tumor seen. Polypoidal mucosal thickening noted in bilateral maxillary, ethmoidal, and right frontal sinuses. Also when I look at the scan films, near the pituitary gland few residual part of the tumor is seen. I am requesting you to have a look at my query and respond me how the report looks like. I am more anxious to know about this. Please help me to understand the current status of my husband's health.
