Ovarian mass. PELVIS:UTERUS, ADNEXA: Anteflexed anteverted uterus. The endometrium is normal in thickness. The junctional zone is normal in thickness. No discrete uterine mass.The right ovary measures 4.2 x 2.4 cm. It contains a well-defined multilobulated 2.9 x 2.6 cm lesion demonstrating very low T2-weighted signal intensity and hypointense T1-weighted. There is minimal to no significant enhancement on postcontrast imaging as best demonstrated on the subtraction images. There is no macroscopic fat within the lesion.The left ovary measures 2.5 x 1.9 cm and is normal in morphology.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Small volume of free pelvic fluid, within physiologic limits.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
The 2.9 cm right ovarian lesion with imaging features suspicious for a fibrous stromal neoplasm (e.g. fibroma, fibrothecoma or Brenner tumor). It demonstrates no macroscopic fat to suggest a dermoid cyst.
