[Large colpohematometra with bilateral hematosalpinx resulting from progressive obstruction caused by incomplete vaginal septum]

Complete or incomplete transverse vaginal septum is a rare malformation of the female genital tract. Usually the complete congenital type occurs at puberty because of the collection of menstrual blood above the septum with amenorrhea and cyclic lower abdominal pain as presenting symptoms. On the contrary, in the case shown by the authors, the subacute epilogue occurred in the perimenopausal phase: a very large colpohematometra is reported in a 49 years old woman, with an incomplete vaginal septum resulting in progressive obstruction. The association between this malformation and the presence of endometriotic localizations in the genital tract, as reported by other authors, is interesting. In this case, endometriosis can be secondary to the presence of the septum or could have determined the impairment of the obstruction in consequence of the associated status of chronic flogosis.
