Abstract:
Background:
This case report describes a case of Müllerian duct cyst that occurred in a male retroperitoneum. The cyst lesion is rare and complicated with
diaphragmatic hernia. Müllerian duct-derived cyst is a rare developmental disorder that is more common in male pelvic tissues and rare in the
retroperitoneum. We investigated the important role of computerized tomography (CT) and magnetic resonance imaging (MRI) in preoperative
diagnosis and disease prediction of this condition.
Case Presentation:
A 25-year-old male was found to have an abnormal occupying lesion in the left diaphragm in imaging examinations, usually healthy with no
obvious clinical symptoms. X-ray examination showed a circular, high-density shadow near the left diaphragm. CT scan showed a soft tissue
density shadow resembling a tumor in the left adrenal area, irregularly protruding into the chest cavity, with uneven density. MRI examination
showed an irregular elongated T1 and T2 signal shadow in the left adrenal area. T2 fat suppression showed high signal intensity with unrestricted
diffusion. Robotic-assisted laparoscopic surgery showed left retroperitoneal tumor resection. The patient recovered well postoperatively and had no
recurrence after discharge follow-up.
Conclusion:
The preclinical symptoms of retroperitoneal Müllerian cysts complicated by diaphragmatic hernia in young men are difficult to distinguish, and it
is difficult to diagnose other similar cysts with imaging. The method of combined CT and MRI diagnosis guides the endoscopic robot-assisted
minimally invasive surgery for excision of cysts to achieve accurate diagnosis and treatment of such diseases.
