We report a case of a 49-years-old woman with a history of cervical cancer treated surgically who, after 2 year of follow-up, started to have stress urinary incontinence. The MRI performed showed a cystic mass in the right pelvis, suspected to be a lymphocele. Subsequent examinations showed an increase in volume of the mass, and the MRI (magnetic resonance imaging) performed 5 years after demonstrated an unexpected connection between the mass and the cecum; therefore, it was suspected to be a mucocele. Because of the risk of rupture with possible development of pseudomixoma peritonei and considering also in this case its suspicious morphological features, our Patient has been subjected to a laparotomic surgery. The final histopathological diagnosis was a low-grade appendiceal mucinous tumor. Because of initial suspicion of lymphocele and the normal process of follow-up of the patient, we were able to find and re-evaluate previous exams, so it was possible to reconstruct retrospectively the rate of mass growth over time by MRI. Our case is the first of which can be documented over time with MRI the rate of growth for year and during six years of a cystadenoma of the appendix. Moreover, our case describes the development in the immediate follow-up of a mucocele of the Appendix, in a patient treated for cervical cancer.
