Early Diagnosis of Imperforate Hymen in a Pediatric Patient: A Case Report.

An imperforate hymen is a rare congenital anomaly of the female genital tract. It leads to hematocolpos and hematometra due to obstructed menstrual outflow. It can present with primary amenorrhea, cyclic abdominal pain, and urinary retention. It typically remains undiagnosed until puberty. We report the case of an 11-year-old girl who presented with a two-month history of cyclic lower abdominal pain and a two-day history of acute urinary retention and constipation. Physical examination and imaging confirmed the diagnosis of hematometrocolpos secondary to an imperforate hymen. The patient underwent surgical intervention with the successful resolution of symptoms. Timely diagnosis and prompt surgical intervention are crucial to achieve symptom resolution and prevent further complications. Early recognition is essential to avoid a delayed diagnosis that can lead to significant discomfort, urinary retention, and potential reproductive consequences. Proper postsurgical follow-up ensures normal menstrual function, reproductive health, and long-term well-being. This case highlights the importance of early recognition of imperforate hymen to ensure normal reproductive health and prevent long-term complications.
