Overview
On transvaginal ultrasound, endometrial cancer is characterized by thickening of the endometrium and disruption of a subendometrial halo.
Ultrasound
Dysgerminomas[1]
- May be seen as a septated ovarian mass with varying echotexture. Colour Doppler interrogation may show prominent flow signal within the fibrovascular septa.
Ovarian dermoid[2]
- Ultrasound is the preferred imaging modality. Typically an ovarian dermoid is seen as a cystic adnexal mass with some mural components. Most lesions are unilocular.
- The spectrum of sonographic features includes:
- Diffusely or partially echogenic mass with posterior sound attenuation owing to sebaceous material and hair within the cyst cavity
- Echogenic interface at the edge of mass that obscures deep structures: the tip of the iceberg sign
- Mural hyperechoic Rokitansky nodule: dermoid plug
- Echogenic, shadowing calcific or dental (tooth) components
- Presence of fluid-fluid levels
- Multiple thin, echogenic bands caused by hair in the cyst cavity: the dot-dash pattern
- Colour Doppler: no internal vascularity
- Internal vascularity requires further workup to exclude a malignant lesion
Immature ovarian teratoma[3]
- Ultrasound appearance can be as a heterogeneous adnexal mass although is non-specific. Calcifications may be present
Ovarian yolk sac tumour[4]
- The tumour typically manifests as a large, complex pelvic mass that extends into the abdomen and contains both solid and cystic components
- The cystic areas are composed of epithelial lined cysts produced by the tumour or of co-existing mature teratomas
- Bilaterality is rare.
- Tends to have both echogenic and hypoechoic components.
Ovarian choriocarcinoma[5] On imaging, choriocarcinomas appear as vascular solid tumours with cystic, haemorrhagic, and necrotic areas.
