A. Axial T1W MR image with fat saturation shows bilateral ovarian endometriomas with marked and uniform hyperintensity with a “light bulb bright” appearance, demonstrating hematic content. U: Uterus. B. Axial T2W MR image shows bilateral ovarian endometriomas (E) with decreased signal on T2W (T2 shading) that reflects the varying chronicity of blood products from repeated haemorrhage. Yellow arrows show a deep endometriosis plaque in the retrocervical space, with extension to the left ovarian fossa and anterior rectal wall. U: UterusC. Transvaginal ultrasound showing a unilocular cyst with regular walls and homogeneous ground glass echogenicity, compatible with endometrioma (E) with small hyperechogenic focus in the wall (yellow arrow).
