Radiology · Gynaecological imaging: postmenopausal endometrial thickness

Sample item

A 60-year-old woman has postmenopausal bleeding. On transvaginal ultrasound, which endometrial thickness is generally regarded as low risk and reassuring?

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

The answer and the reasoning

C. 4 mm or less

In women with postmenopausal bleeding, an endometrial thickness of 4 mm or less has a very low risk of cancer, and thicker endometrium needs sampling by biopsy or hysteroscopy. Persistent bleeding warrants further evaluation despite a thin lining.

Option by option

  • A. 25 mm

    25 mm is markedly abnormal.

  • B. 8 mm

    8 mm exceeds the threshold and needs sampling.

  • C. 4 mm or less (correct)

    Correct. 4 mm or less carries a very low chance of endometrial cancer.

  • D. 15 mm

    15 mm is definitely thickened.
