Transvaginal ultrasound is the initial imaging investigation of choice for patients presenting with the usual symptom of a postmenopausal bleed. A thickened endometrium requires endometrial sampling.
** Thickening of the [[endometrium]]
*** Premenopausal women have endometrial thickness that varies through the menstrual cycle
*** Postmenopausal women show increased thickness > 5mm
*** Thickness > 8mm is seen in postmenopausal women taking tamoxifen


Transvaginal ultrasound
* Endometrial carcinoma usually appears as thickening of the endometrium though may appear as a polypoid mass
* premenopausal: normal endometrial thickness varies through the menstrual cycle
* diagnosing abnormally thickened endometrium depends on knowing what the patient's point in the menstrual cycle
* postmenopausal: >5 mm is thickened (if not on Tamoxifen)
* Sonographic features are non specific and endometrial thickening can also be due to benign proliferation, endometrial hyperplasia or polyps.
* Disruption of a subendometrial halo on ultrasound may be suggestive of myometrial involvement.
* Disruption of a subendometrial halo on ultrasound may be suggestive of myometrial involvement.

Overview

On transvaginal ultrasound, endometrial cancer is characterized by thickening of the endometrium and disruption of a subendometrial halo.

Transvaginal ultrasound

  • Transvaginal ultrasound may be helpful in the diagnosis of endometrial cancer. Findings on an ultrasound suggestive of endometrial cancer include:[1]
    • Thickening of the endometrium
      • Premenopausal women have endometrial thickness that varies through the menstrual cycle
      • Postmenopausal women show increased thickness > 5mm
      • Thickness > 8mm is seen in postmenopausal women taking tamoxifen
  • Disruption of a subendometrial halo on ultrasound may be suggestive of myometrial involvement.
