Torsion of paratubal cyst mimicking ovarian torsion: A rare case of difficult diagnosis.

Introduction: Paratubal cysts are frequent lesions, and may be responsible for complications such as adnexal torsion, which is rare and difficult to diagnose. Management requires emergency surgery in an attempt to preserve the adnexa.

Presentation Of Case: We report a rare case of a young patient admitted with a Torsion of paratubal cyst mimicking ovarian torsion, the positive diagnosis was difficult.

Discussion: Paratubal cysts are lesions that constitute around 10 % of adnexal masses, and may have their embryological origin in Wolfian remnants. Morgagni's hydatid is by far the most common form. Torsion of a para-tubal cyst may manifest as sudden, continuous, or rapidly worsening pain in the iliac fossa. Ultrasound should systematically seek to identify the ovaries outside the lesion. Isolated tubal torsion can only be treated surgically. Laparoscopy is the gold standard.

Conclusion: Paratubal cyst torsion is rare and very difficult to diagnose, but should be systematically considered in the case of an adolescent presenting with acute pelvic pain.
