case_images: (a) Transrectal ultrasound appearance of a cystic mass (arrow). (b) Axial T2-weighted magnetic resonance imaging (MRI) at the first hospitalization revealing a normal ovary and a hydrosalpinx (arrow). (c) The hydrosalpinx shows a gradual reduction in size (arrows) on MRI.

case_images: In the evaluation at our obstetrics and gynecology department, her abdominal pain had completely resolved, and the transrectal US showed a cystic structure and normal uterus and ovaries (Figure 1(a)). MRI revealed a tortuous tubular structure in the left pelvis, with the inner part of the lesion showing a water-like density, with no signs of malignancy (Figure 1(b)). MRI, which was performed every three months during the observation period, showed a gradual decrease in the size of the hydrosalpinx (Figure 1(c)); hence, we continued to monitor her symptoms carefully.
case_images: Torsion of the left fallopian tube (laparoscopic intraoperative image).

case_images: Intra-abdominal observation revealed a left fallopian tube with torsion (360  clockwise rotation) and swelling of the entire tube (Figure 2).
case_images: (a) High-power field of hematoxylin and eosin-stained resected left fallopian tube. (b) Immunohistochemistry for p53 showing focal and very weak staining. There is no evidence of malignancy.

case_images: Focal nuclear hyperchromasia was observed; however, the tubal epithelial structures were preserved (Figure 3(a)). Immunohistochemistry showed nonspecific weak staining for p53, with no evidence of malignancy (Figure 3(b)).
