Imperforate hymen is a rare congenital anomaly of the vagina generally presented with symptoms in pubertal girls. A case of 13 year old girl with an imperforate hymen is reported here. She presented with cyclical lower abdominal pain and a suprapubic mass. Perineal examination is diagnostic and confirmed by ultrasound pelvis and abdomen. After reassurance and counselling a hymenectomy was performed. The prognosis is good with surgical intervention. A follow up of 4-6 weeks showed no recurrence.
