Patient Data

Age: 30 years
Gender: Female

The right ovary shows a cystic lesion with internal hyperechoic globular components without definite internal color flow, it measures about 5 x 2.5 cm.

The left ovary shows a cystic lesion with an internal hyperechoic component and multiple septations, it measures about 5 x 3 cm.

There are bilateral multiloculated ovarian lesions showing predominant fat component with another heterogenous enhancing component, it measures 5.3 x 2.8 cm in the right ovary and 7.1 x 4.8 cm in the left ovary without definitely restricted diffusion.
Findings are mostly representing bilateral mature cystic teratomas (dermoid cysts).

Multiple dilated parauterine veins reaching 9 mm in diameter.

Minimal pelvic free fluid is noted.


Sections of the right ovarian cyst reveal fragmented ovarian cyst, showing skin with its adnexa, mature adipose tissue, cartilage, bone, colonic wall and neural tissue with reactive gliosis.

The left side shows similar findings in thyroid follicles and respiratory mucosa.

No evidence of an immature neural element of malignancy was seen in the levels examined.


(1) Right ovarian cyst, cystectomy: - consistent with mature cystic teratoma.

(2) Left ovarian cyst, cystectomy: - consistent with mature cystic teratoma.
