Solid ovarian tumour: histology unknown

MRI shows an ovarian mass with low signal in T1 and T2 images and homogeneous enhancement.
No vascular signal void is seen between the uterus and the mass.
Fibrothecomas and Brenner tumours have low signal intensity on T1- and T2-weighted images, representing the fibrous component. Brenner tumors are reported to show lower signal intensity on T2-weighted images than other solid tumours
Scattered high-signal-intensity areas in the mass represent edema or cystic degeneration. In masses with cystic degeneration, the solid component is usually located peripherally.
Differential considerations include uterine leiomyomata and other ovarian masses with fibrous components (fibroma, cystadenofibroma, Fibrothecomas and Brenner tumour).
