Overview
Pelvic ct scan may be helpful in the diagnosis of sexcord/ stromal ovarian tumors. Findings on CT scan suggestive of sexcord/ stromal ovarian tumors include multicystic masses with solid components and either irregularly thickened or thin septations for both adult and juvenile granulosa cell tumors, Fibromas on delayed contrast-enhanced computed tomography usually shows a solid, well-defined, homogeneous ovarian mass which is isodense to the uterus with very sparse contrast uptake. Sclerosing stromal tumor will show peripheral contrast uptake, reflecting prominent vasculature in the cellular areas, with centripetal progression on late images. Leydig tumors tend to be small and hypoattenuating.
CT scan
- CT scan may be helpful in the diagnosis of sexcord/ stromal ovarian tumors[1][2][3][4][5][6][6][7][8][9]
- Findings on CT scan suggestive of/diagnostic of the tuomors include:
- Both Adult and juvenile granulosa cell tumors appear as multicystic masses with solid components and either irregularly thickened or thin septations
- Sclerosing stromal tumor will show peripheral contrast uptake, reflecting prominent vasculature in the cellular areas, with centripetal progression on late images
- Leydig tumors tend to be small and hypoattenuating
- Fibromas on delayed contrast-enhanced computed tomography usually shows a solid, well-defined, homogeneous ovarian mass which is isodense to the uterus with very sparse contrast uptake
- Some degree of calcification may be present and, as these tumors enlarge, myxoid or cystic degeneration may occur, showing a heterogeneous pattern
