If a galactocele becomes infected and forms an abscess, what is the expected blood flow pattern on Doppler?

Explanation:
Inflammation drives increased blood flow around an infected lesion. When a galactocele becomes infected and forms an abscess, the surrounding inflammatory tissue shows hyperemia on Doppler, so the color flow is greatest at the periphery of the lesion while the center remains relatively avascular due to the pus-filled cavity. Central flow would suggest a different type of vascular lesion, while no flow or decreased flow isn’t typical of an acute infectious abscess. Thus, the expected pattern is peripheral blood flow due to inflammation.
