case_images: fig1
case_images: 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).
case_images: Ultrasonography shows well-defined anechoic cystic lesion about 2 cm diameter with posterior acoustic enhancement (arrows).

case_images: fig2
case_images: US was performed, and a well-defined, ovoid shaped, approximately 2-cm in diameter anechoic cystic lesion was observed (Figure 2).
case_images: The axial T1-weighted MR image shows the lesion with a homogeneous hypointensity (arrow).

case_images: fig3
case_images: 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).
case_images: The sagittal T2-weighted MR image shows hyperintense lesion in the lower nasal fossa (white arrow) and bone erosion (black arrows).

case_images: 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).
case_images: The axial T2-weighted fat-saturated image shows the well circumscribed lesion with a homogeneous hyperintensity (arrow).
