An uncommon cause of persistent infection by Trichomonas vaginalis

Trichomonas vaginalis infection typically exhibits a favorable response to treatment. Nonetheless, there are instances where complete eradication proves challenging, necessitating multiple treatment cycles. Understanding patient history and conducting thorough examinations are crucial in identifying the reasons behind therapeutic failures. We present a case study involving a patient with persistent trichomoniasis despite multiple treatment cycles, attributed to the presence of an intrauterine device inserted several years prior. This case underscores the intricacies involved in managing recurrent Trichomonas vaginalis infections and the importance of a comprehensive evaluation.
