Which inflammatory condition is described as inflammation within the fallopian tube and appears as a thick tubular adnexal mass?

• A. Endometritis
• B. Salpingitis
• C. PID
• D. Endometriosis

Answer: (B)

Salpingitis is inflammation of the fallopian tubes. On ultrasound, inflamed tubes become thickened and often dilated, producing a thick tubular adnexal mass adjacent to the ovary. This Tubo-ovarian complex appearance is a classic sign of infection affecting the upper female genital tract, which is the setting of pelvic inflammatory disease. Endometritis would involve the uterine lining rather than the tubes, while endometriosis refers to ectopic endometrial tissue and typically shows ovarian endometriomas or pelvic nodules rather than a primary tubular inflammatory mass. PID can include salpingitis as a component, but the description given points most directly to inflammation of the tube itself.
