Distal mesonephric anomalies with unilateral blind hemivagina and ipsilateral renal agenesis. a MR image corresponding to a 16-year-old patient suffering from strong dysmenorrhoea. After clinical examination and MR, she was diagnosed with endometrioma. However, a dydelphys uterus and right haematocolpos (*) can be observed. T2-weighted MR image, sagittal plane. RO, Right ovary; RU, right hemiuterus (taken from Acién and Acién, Hum Reprod Update 2016;22:48–69, figure 1A1, with permission). b An 18-year-old patient presenting with unilateral haematocolpos. Colpo-hysterography after injection of a contrast agent in the right blind hemivagina showing the contrast output through an interuterine communication and left hemivagina (<). c Ectopic ureter. HSG image obtained with a small Foley catheter (>) showing the findings in a patient who underwent previous adhesiolysis and Strassman operation abroad. Left blind hemivagina (**), communicating uteri (>>), left ectopic ureter (<<) and possible mesonephric remnants (<) can be observed (modified from Acién et al., Eur J Obstet Gynecol Reprod Biol 2004;117:105–108, with permission). d Three-dimensional ultrasound image showing a septate uterus and left blind hemivagina (now perforated) 1 year after drainage of haematocolpos and haematometra (courtesy of Dr. M.
