Imperforate hymen is an uncommon defect. Ultrasound may be useful in diagnosing hematocolpos, which is a common complication of imperforate hymen. The rectal approach with the ultrasound probe is an excellent method in aiding the diagnosis when the transvaginal approach is not feasible.
Imperforate hymen was suspected in an amenorrheic, 13-year-old girl who complained of cyclic lower abdominal pain. Her pubic hair and breast development were Tanner stage 3. Abdominal and pelvic examination confirmed a tender pelvic mass. A bluish, bulging hymen was noted. Abdominal ultrasound revealed a pelvic cystic mass. Rectal ultrasound confirmed the diagnosis of hematocolpometra.
Transrectal sonography provides an excellent alternative to transvaginal ultrasound in cases where transvaginal ultrasound is not feasible or is impossible. The rectal approach is appropriate due to the close proximity to the pelvic organs and patient acceptance of the procedure.
处女膜闭锁是一种罕见的缺陷。超声可能有助于诊断阴道积血，这是处女膜闭锁的常见并发症。当经阴道途径不可行时，经直肠途径使用超声探头是辅助诊断的一种极好方法。
一名13岁闭经女孩，主诉周期性下腹痛，怀疑处女膜闭锁。她的阴毛和乳房发育处于坦纳3期。腹部和盆腔检查证实盆腔有压痛性肿块。可见处女膜呈蓝色、膨出。腹部超声显示盆腔囊性肿块。直肠超声确诊为阴道子宫积血。
在经阴道超声不可行或无法进行的情况下，经直肠超声检查是经阴道超声的极佳替代方法。由于直肠途径与盆腔器官距离近且患者易于接受该操作，所以该途径是合适的。
