We present two cases of young girls with cyclic abdominal pain and urinary symptoms. At gynaecological examination, they all presented imperforate hymen and ultrasound revealed significant vaginal distension. X-shaped hymenectomy was performed in all patients. The later the diagnosis of imperforate hymen, the higher the risk of complications like haematometra, haematosalpinx, haemoperitoneum and infections such as tubo-ovarian abscesses, peritonitis and endometriosis (retrograde menstruation theory).}, URL = {https://casereports.bmj.com/content/2018/bcr-2018-226041}, eprint = {https://casereports.bmj.com/content/2018/bcr-2018-226041.full.pdf}, journal = {Case Reports} }
