Intravenous leiomyomatosis is a histologically benign smooth-muscle tumor arising from either a uterine myoma or the walls of a uterine vessel with extension into veins. Echocardiographic features of two cases of intravenous leiomyomatosis with extensive spread into the right-sided cardiac chambers and pulmonary arteries are described. ⋯ Distinctive echocardiographic features include 1) elongated mobile masses extending from the veins of the lower body, including inferior vena cava and azygos vein; 2) multiple venous attachments or metastases; and 3) filling of venous vessels and right-heart chambers. Intracardiac leiomyomatosis should be considered in a female patient presenting with an extensive mass in the right-sided cardiac chambers.

Dumon stent placement requires use of a technically difficult rigid bronchoscope. A recently developed technique for placing a Dumon stent introduced via a conventional endotracheal tube is detailed herein. ⋯ While Dumon stent removal may require a rigid bronchoscope or tracheostomy, stents can be introduced without difficulty via a conventional endotracheal tube.
