Hello Dr. Alabdeen,

You may want to include antral pseudocyst (also known as mucous retention phenomenon) in your differential diagnosis. It typically presents as a dome shaped radiolucency extending from the floor of the maxillary sinus.

Hi all
This is an incidental finding when patient came to the implant clinic, patient is not complaining of pain, the panoramic image shows a well defined corticated cyst-like lesion less than 2 mm within the maxillary sinus and not related to #16 and # 17 as seen from the coronal and sagittal sections, the fifth image (coronal view) shows less cortication resembling a soft tissue mass, or a cyst filled with fluid.
Differential diagnosis 
1. Maxillary sinus mucous retention cyst 
2. polyp in maxillary sinus
