Figure 1.

Pelvic MRI revealed a solid oval mass in the right adnexal region. It exhibited iso-signal intensity on T1WI (a), slightly higher-signal intensityonT2WI (b, relative to muscle), and T2WI fat-suppressed axial images (c). The mass possessed a capsule (indicated by the arrow in a,b) and central cystic necrosis (triangular arrow in a,b). The mass displayed marked high intensity on the diffusion-weighted image (B = 800 s/mm2) (d) with restricted diffusion on the ADC map (e). The solid part of the mass exhibited homogeneous and moderate enhancement with intravenous gadolinium-DTPA, and the envelope (arrow) also demonstrated enhancement (f). ADC, apparent diffusion coefficient; MRI, magnetic resonance imaging.

Epithelial tumor cells were arranged in packed strands with a slit or fern-leaf-like structure (HE ×400) (A). Tumor cell cytoplasm was positive for a-inhibin (EnVision method ×400) (B). HE, hematoxylin & eosin.
