Introduction: Appendiceal mucocele is an interesting pathology, given its rarity and its tricky management. The retroperitoneal localization is even more interesting because of its difficulties to diagnosis and treat. Indeed, in case of mucocele is incorrectly treated, pseudomyxoma peritonei may develop, secondary to an intraperitoneal rupture of the mass. Case report: We present here the case of a 50-year-old woman who consulted for a mild right low back pain with palpable abdominal mass. A CT-scan performed showed a large right retroperitoneal mass evoking a retroperitoneal cystic lymphangioma. The patient underwent an exploratory laparotomy, which showed a large whitish retroperitoneal cyst, extending from the right iliac fossa to the right hypochondrium. We suspected during surgery an appendiceal mucocele. During dissection, we assisted to a tumoral rupture. The peritoneal cavity was already protected by surgical drape. We went an en-bloc and complete resection of the tumor. The histological study concluded to a mucinous cystadenoma. After a one-year follow-up, control CT-scans showed no signs of recurrence. Conclusion: Retroperitoneal appendiceal mucocele is a rare disease. A correct radiological pre-operative diagnosis, based on CT-scan, is important to avoid severe intraoperative complications.

“…Like in CT, there is no sign of inflammation or periappendicular collection [14][15][16][17] . MRI is inferior in detecting calcifications compared to CT. Low sensitivity of FDG PET in detecting appendeceal carcinoma limits its use in workup of AM 18,19 .…”

Mucocele of the appendix is a rare disease. Clinically, appendeceal mucocele (AM) is an incidental finding or it may mimic appendicitis. In AM, distension of the appendix is caused by mucus, the source of which can be benign or malignant. For the benign disease, appendectomy alone is sufficient but for malignant conditions adjunct treatments are needed. Proper pre-operative evaluation is imperative to distinguish between benign and malignant causes in order to guide the management and reduce complications. For the definitive diagnosis, histology and immunohistochemistry are required. We report an incidental finding of an appendeceal mucocele in a kidney donor during pre-transplant evaluation.

“…There are only a few references in the literature regarding the potential use of 18 F-flurodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT) to detect underlying malignancy in mucoceles. These show that PET has a rather low sensitivity in detecting underlying malignancy and has limited use in the evaluation of appendiceal carcinomas (28,29).…”

Mucocele of the appendix is a descriptive term of a distended, mucus-filled appendix caused by various conditions, both benign and malignant. Computed tomography is the imaging modality of choice. Correct pre-operative diagnosis is important because of the possibility of peroperative rupture and subsequent development of pseudomyxoma peritonei. It is the task of the radiologist to alert the clinician and surgeon to the presence of this entity, the potential associated complications and possible signs of malignancy.
