case_images: The T1-weighted sequences showed downward herniation of the ethmoidal roof on the right nasal cavity and T2-weighted coronal, and sagital imaging confirmed a liquid-filled mass in the right ethmoidal sinus and nasal cavity projecting through a defect in the ethmoidal roof (Figures 1 and 2).
