Cryptomenorrhoea due to imperforate hymen: a case report
Keywords:imperforate hymen, primary amenorrhoea, genital anomaly, puberty
Imperforate hymen is a rare obstructive congenital anomaly of the female genital tract which arises as a result of complete failure of canalisation of the inferior end of the vaginal plate at the junction between the urogenital sinus and the vagina. Its prevalence is 0.05%-0.1%. We are presenting a case of 14 years old girl who came with complaints of lower abdominal pain since 10 days not associated with nausea, vomiting and diarrhoea. She had not attained menarche but her secondary sexual characters were developed with breast, pubic and axillary hair in tanner stage 4. MRI revealed hematocolpos and hematometra with imperforate hymen. Hymenotomy was performed and 300-400 ml of thick tarry colour blood was drained. Her postoperative period was uneventful, and patient was discharged in satisfactory condition. On follow up after 1 month, patient resumed normal menses.
