Teeth in an ovarian dermoid cyst on hip x-ray

Case contributed by Assoc Prof Craig Hacking


Lateral thigh pain.

Patient Data

Age: 50 years
Gender: Female

Left hip joint alignment is normal and there is no joint space narrowing or evidence of arthropathy. Bone density is within normal limits.

Incidental teeth-shaped densities are projected in the left side of the pelvis, most in keeping with ovarian dermoid. If required, this could be confirmed with ultrasound.

Case Discussion

Ovarian dermoid cysts (or mature cystic teratomas) are composed of tissue elements of 2 or 3 of the embryological layers. The ectodermal component may differentiate into dental structures, as in this case, and be evident of plain film imaging.
