Pelvic Inflammatory Disease

Pelvic inflammatory disease (PID) is a pathology of a woman's reproductive organs that originates from an infectious process spread through the cervix to the uterus, fallopian tubes up to the ovaries, and pelvic peritoneum. PID is the main gynecological cause of acute pelvic pain in the women, but in many cases it is completely asymptomatic. The most frequent symptoms are lower abdominal pain, fever, symptoms of lower genital tract infection, and dyspareunia. It is important to make a correct differential diagnosis between PID and rupture of active endometrioma, which causes an important pelvic inflammatory process highly vascularized at power Doppler (PD) detection in a patient with acute pelvic pain. The PD technique provides more information in the evaluation of PID than the conventional color Doppler, such as the capacity to show areas of undetectable flow.
