Ultrasound (US) images of a 25-year-old woman with a mature cystic teratoma. B-mode transabdominal US image showing a heterogeneous lesion with an echogenic mural nodule (dermoid plug) (red arrow).

Furthermore, there was also an echogenic mural nodule compatible with the Rokitansky nodule (dermoid plug) within the heterogeneous lesion (Figure 1).
Axial contrast-enhanced abdominopelvic computed tomography images showing presence of enlarged uterus (red arrow) (A) consistent with early postpartum period and a normal appendix (red arrow) (B). Also note the non-enhancing ovarian mass (white arrow).

An abdominal contrast-enhanced computed tomography (CT) scan of the abdomen showed that the appendix is normal and the uterus increased in size (Figure 2).
Axial contrast-enhanced abdominopelvic computed tomography image revealing intralesional fat (white arrow) and calcification (red arrow). Note the non-enhancing component of the lesion (arrowhead).

Furthermore, CT demonstrated a heterogeneous density lesion containing subtle peripheral calcification, fat and fluid density areas in the right adnexa consistent with a MCT (Figure 3).
Surgical specimens showing unilocular cysts filled with sebaceous material, hair, and focal solid area with calcification area.

We performed a small transverse incision that allowed the externalization of the ovarian mass containing hair, sebum, and calcifications in the right adnexa (Figure 4).
Low power microscopic view (A) showing tissue lined by stratified squamous epithelium with associated hair follicles and sebaceous glands. High power microscopic view (B) showing in the surface lined by stratified squamous epithelium with associated hair follicles and sebaceous glands. Microscopic (C); hair shaft material. Extensive hemorrhage, congestion, dilated blood vessels, and ischemia of mucosa and parenchyma (D).

Surgical specimen and histopathological examination showed that unilocular cysts filled with sebaceous material, hair and focal solid area, extensive hemorrhage, congestion, dilated blood vessels, and ischemia of mucosa and parenchyma (Figure 5).
