Brief Answer:
Mild right maxillary sinusitis

Detailed Answer:
Hi. Thank you for writing to HCM.

Moderate circumferential mucosal thickening in the right maxillary antrum means there is some inflammation in the right maxillary sinus and is a sign of early or mild sinusitis.

This may have nothing to do with her gait. Problems in gait may be neurological and the MRI may need to be reviewed by a neurologist to assess the motor areas of the brain and the cerebellum.

For the sinusitis, your granddaughter is advised to see an ENT specialist for antibiotics and anti inflammatory medications. A CT scan is a better investigation to evaluate sinusitis and may be taken if necessary.

Hope this information helps. Do let me know if you have any further questions.

Brief Answer:
Cerebellar abnormality can cause gait problems

Detailed Answer:
Hi. Thank you for writing back.

Bilateral cerebellar tonsillar ectopia probably means the cerebellar tonsils are lower than what they should be and may lead to gait disturbances or respiratory difficulties based on the amount of compression from surrounding structures.

Do follow up with a neurologist for a thorough evaluation and management based on symptomatology.

Hope this helps. Do let me know if you have any other questions.
