[Coincidence of hydatid of Morgagni and undescended testis: more common than expected !]

As part of a retrospective data analysis over a period of 6 years, the coincidence of undescended testis and hydatid of Morgagni (appendix testis) was examined on the basis of 814 operated testes. The overall prevalence of hydatids after opening of the testicular envelope of undescended testes was 62.66%. In addition, we were able to establish a correlation between patient age and the hydatid size. According to the results of the study, the size of the hydatid-with growth most likely to be influenced by hormones-can be assumed to be associated with the patient's age.
