RESUMO
Las lumbalgias son frecuentes en niños y adolescentes. La mayoría tienen un origen mecánico benigno y transitorio. Se presenta el caso de una paciente de 12 años con lumbalgia persistente como único síntoma de hematocolpos por himen imperforado. La himenectomía resolvió totalmente la lumbalgia. Por su rareza, los pediatras no solemos pensar en esta posibilidad por lo que proponemos que ante una adolescente con lumbalgia persistente y amenorrea primaria aparente es necesario valorar el diagnóstico de hematocolpos por himen imperforado
Low back pain is common in children and adolescents. Most of those cases have a benign, transitory and mechanical origin. We present the case of a 12-year-old patient with persistent low back pain as the only symptom of hematocolpos due to imperforate hymen. The hymenectomy completely resolved the low back pain. Due to its rarity, pediatricians do not usually think about this possibility, so we propose that in a case of an adolescent with an adolescent with persistent low back pain and apparent primary amenorrhea, it is necessary to think about the diagnosis of hematocolpos due to imperforate hymen
