There were no bony changes in the orthopantomography and occlusal radiography examinations, and all of the associated teeth were shown to be vital using electrical pulp testing (Figure 1).
Ultrasonography shows well-defined anechoic cystic lesion about 2 cm diameter with posterior acoustic enhancement (arrows).

US was performed, and a well-defined, ovoid shaped, approximately 2-cm in diameter anechoic cystic lesion was observed (Figure 2).
The axial T1-weighted MR image shows the lesion with a homogeneous hypointensity (arrow).

The relevant cystic lesion exhibited a homogeneous hypoisointense (with adjacent soft tissue) appearance on the T1-weighted images and a homogenous hyperintense appearance on the T2-weighted images (Figures 3, 4, and 5).
The sagittal T2-weighted MR image shows hyperintense lesion in the lower nasal fossa (white arrow) and bone erosion (black arrows).

The relevant cystic lesion exhibited a homogeneous hypoisointense (with adjacent soft tissue) appearance on the T1-weighted images and a homogenous hyperintense appearance on the T2-weighted images (Figures 3, 4, and 5).
The axial T2-weighted fat-saturated image shows the well circumscribed lesion with a homogeneous hyperintensity (arrow).
