Gamut of infectious conditions of upper reproductive tract
Endometritis, salpingitis, TOA
Source : ascending infection
N. gonorrhoeae, C. trachomatis : 2/3
Aching pain usually occurs 7-10 days after mensturation
Early stage : US & CT findings : normal
<Early Stage CT finding>
CT findings are typically subtle.
1.Often the only finding is mild pelvic edema
•
thickening of the uterosacral ligaments
•
haziness of the pelvic fat with obscuration of the pelvic fascial planes
2.Mild salpingitis with inflammatory thickening of the fallopian tubes
thickened fallopian tubes :salpingitis
3.Mild oophoritis with enlarged and abnormally enhancing ovaries that may demonstrate a polycystic appearance
Normal Ovary : 1.5~3 cm enlarged, inflamed, and have a polycystic appearance due to early oophoritis
4.Periovarian stranding and enhancement of the adjacent peritoneum
Pelvic fat infiltration
5.Abnormal endometrial enhancement and simple fluid within the endometrial canal are findings that are consistent with endometritis
Abnormal endometrial enhancement and simple fluid: endometritis
Ovarian engorgement
6.Uterine cervix may also be enlarged and contain an abnormally enhancing endocervical canal, findings that are consistent with cervicitis
Enlarged cervix
Abnormal enhanced edocervical canal
Pericervical inflammation
Pelvic fat infiltration
7.Ant. Displacement broad ligament
<Adcanced PID CT findings>
1. Pyosalpinx
the fallopian tubes exhibit an even greater degree of wall thickening and enhancement and fill with complex fluid
2. TOA and Pelvic abscess formation
presence of a thick-walled, complex fluid collection that may contain internal septa, a fluid-debris level, or gas(rare)
