case_images: Transvaginal ultrasound imaging of the periappendiceal abscess misdiagnosed as pyosalpinx. The presence of a tubular structure in the true pelvis (indicated by yellow arrows) led to the misdiagnosis of a pyosalpinx.

case_images: Transvaginal ultrasonography revealed the presence of a tubular formation in the true pelvis, indicating a possible pyosalpinx (Figure 1).
case_images: Computed tomography imaging of the periappendiceal abscess misdiagnosed as pyosalpinx. An organized, thick-walled fluid collection with a spindle-shaped morphology (red arrows) is clearly visualized, along with increased opacification, diffuse fat exudation in the pelvis, and edematous imaging of the rectosigmoid (yellow arrows).

case_images: Additionally, increased opacification and fat exudation were noted diffusely in the lesser pelvis, along with edematous imaging of the rectosigmoid; these findings were considered more consistent with pelvic inflammatory disease (Figure 2).
