Radiology · Gynaecological imaging: endometrioma

Sample item

A woman with dysmenorrhoea and infertility has a unilocular adnexal cyst with homogeneous low-level echoes on ultrasound, which shows T1 hyperintensity and T2 shading on MRI. What is the diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Endometrioma

Endometriomas contain old blood with a ground glass echo pattern on ultrasound, and T1 hyperintensity with T2 shading on MRI. A simple cyst is anechoic. A teratoma loses signal on fat saturation.

Option by option

  • A. Ovarian carcinoma

    Carcinoma shows solid papillary components with vascularity.

  • B. Endometrioma (correct)

    Correct. Ground-glass echoes with T2 shading indicate an endometrioma.

  • C. Simple follicular cyst

    A simple cyst is anechoic without internal echoes.

  • D. Mature teratoma

    A teratoma contains fat that suppresses on fat-saturated sequences.
