The canal of Nuck is an abnormal patent pouch of the parietal peritoneum caused by the incomplete obliteration of the processus vaginalis in females. The most common disorders of the canal of Nuck are: hernia, hydrocele and endometriosis. Pseudomyxoma Peritonei (PMP) is a clinical condition characterized by the accumulation of mucinous material on the surfaces and in the recesses of the peritoneal cavity, resulting from the perforation of an appendiceal mucinous neoplasm. We report the case of a young woman with a clinical history of chronic pelvic pain and infertility who was referred to our center after being diagnosed with appendiceal mucinous neoplasm and PMP. MRI staging examination revealed the right canal of Nuck filled with mucinous material, which was confirmed at surgery. The involvement of canal of Nuck is extremely rare in PMP. MRI provides a sensitive imaging modality for appropriate preoperative planning of PMP and helps surgeons identify uncommon disease sites such such as the canal of Nuck in women, which, if missed, may prevent complete cytoreductive surgery.
