Unveiling the uncommon: Mounier-Kuhn syndrome as a cause of uterine prolapse.

Congenital tracheobronchomegaly, also known as Mounier-Kuhn syndrome (MKS), is an uncommon illness characterised by dilatation of the major bronchi and recurrent chest infections. Tracheobronchomegaly may also be accompanied by tracheal and bronchial diverticula. We report the case of a middle-aged woman with a complaint of uterine prolapse for which a hysterectomy is planned. The patient complained of recurrent cough with expectoration for the last 6 years; hence, a radiograph of the chest and CT of the thorax were advised. A radiograph of the chest and thoracic CT showed dilation and numerous diverticula of the trachea and bronchi that suggested MKS. Management of MKS in symptomatic patients is supportive but is only used to treat contagious exacerbations with antibiotics and respiratory exercise to clear secretions. Here is an attempt to reach out to the cause of uterine prolapse in this patient with MKS and correlating these two conditions.
