Paratubal cysts: frequency, histogenesis, and associated clinical features.

A review of 79 cystic lesions found in the routine study of the fallopian tube and its surrounding areas between the years 1980 and 1982, revealed that the majority of the lesions represented accessory lumina of the fallopian tube. These tubal cysts commonly have been described as hydatids or parovarian cysts, but their relationship to the normal tube has not been identified clearly, their frequency has not been determined, their clinical significance rarely has been considered, and their embryologic origin remains imperfectly understood.
