Presentation
Lower abdominal pain since 2-3 days, more on the left side.
Patient Data
MRI pelvis shows T2 hyperintense and T1 hypointense retort-shaped lesion in left adnexa (separate from left ovary) measuring 10.2 cm in length and 2.3 cm in maximum width - representing hydrosalpinx.
There is twisting of lateral end of dilated left fallopian tube, best seen on coronal T2 image - representing torsion.
Left peritubal edema is noted with minimal fluid in pouch of Douglas.
Uterus and both ovaries appear normal.
Case Discussion
Adnexal torsions include isolated ovarian torsion, combined tubo-ovarian torsion and isolated torsion of fallopian tube.
Isolated torsion of a Fallopian tube is rare. Hydrosalpinx is a pre-existing risk factor for torsion.
