Color Doppler ultrasound cannot reliably distinguish benign from malignant endometrial polyps. Nonfunctional polyps, often found incidentally, are associated with older patients and lack of vaginal bleeding.

Area of Science:

  • Gynecology
  • Radiology
  • Pathology

Background:

  • Endometrial polyps are common, with increasing diagnoses due to advanced imaging.
  • Malignancy in endometrial polyps is rare, but distinguishing benign from malignant types noninvasively is desirable.

Purpose of the Study:

  • To evaluate the utility of color flow Doppler ultrasound in differentiating endometrial polyp subtypes.
  • To correlate Doppler parameters and patient demographics with histopathologic findings.

Main Methods:

  • Observational study involving 61 patients with endometrial polyps.
  • Color Doppler ultrasound was used to assess polyp volume, resistive index (RI), and pulsatility index (PI).
  • Data were correlated with histopathologic examination (nonfunctional, proliferative, secretory, hyperplastic, malignant).

Main Results:

  • No significant differences in RI, PI, or size were found across histologic categories.
  • Patient age was significantly higher in the nonfunctional polyp group.
  • Functional polyps were primarily detected due to abnormal bleeding, while nonfunctional polyps were often incidental findings.

Conclusions:

  • Objective assessment of blood flow impedance and polyp size via Doppler ultrasound is insufficient to replace surgical removal and pathologic evaluation for determining histologic type.
  • Nonfunctional endometrial polyps are associated with older patients and a lower incidence of vaginal bleeding.
