information, bilateral hydrometra of both uterine horns in this report was induced by an obstruction caused by seg-mental aplasia of the uterine body. The segmental uterine horn or vagina are attached to the uterine body or remaining uterine horn either by a thick band of fibrous connective tissue,7,11 or by intermingled fibrous and smooth muscles,2 respectively. In this case, a string-like piece extended from the cord-like piece and became attached to the point of division of the uterine horns. Interestingly, this string-like piece consisted of a round cluster of spindle cells and was therefore thought to be highly undeveloped rudimentary tissue of the uterine body. Alternatively, this tissue may be a part of a broad ligament because broad lig-aments contain a considerable amount of smooth muscle.6 Gee et al.2 described cyst-like structures on a transverse sec-tion of a segmental aplastic vagina, which could be evidence of incomplete canalization in the rudimentary tissues.
