We describe sonographic findings of pelvis inflammatory disease. The diagnosis of initial acute PID (acute salpingitis) begins with a challenge for the doctor, due to the little sensibility of the clinic's criteria. The accumulation of pus inside the fallopian tube gives a location for the tubaric abscess or pyosalpinx, whose characteristic signal is the presence of purulent material in considerable quantities and is visible by means of a sonograph inside the tubal light. We refer a series of characteristic sings that advise us.

The sonographic diagnosis of pelvic inflammatory disease (PID) is a challenge for the sonographer. Sonographic diagnosis is possible when tube enlarges and liquid accumulates inside the fallopian tube, a sign that can be detected with vaginal probes. As the disease progresses, more complex images are found depending on the enlarging of the adnexa and the accumulation of necrotic material. Sonography allows a sensitive diagnostic suspicion in the case of women with clinical and epidemiologic criteria for PID.
