Imperforate hymen is an uncommon obstructive anomaly of the female reproductive tract. Although it is usually sporadic, familial cases have been reported. The patient usually presents with intermittent abdominal pain. Acute urinary retention is a rare symptom. It is rarely diagnosed in the neonatal period, and most cases occur in the adolescent period. Pelvic ultrasonography is the essential initial diagnostic radiological modality to confirm the diagnosis. We report a 13 year-old girl who presented main complaint of acute urinary retention and hematocolpos diagnosed by ultrasonography due to imperforate hymen.
Key Words: Imperforate hymen, Hematocolpos, Ultrasonography.
