AbstractTo assess the diagnostic impact of transesophageal echocardiography in the evaluation of mediastinal masses, 30 patients with mediastinal abnormalities detected by routine chest roentgenogram underwent transthoracic and transesophageal echocardiography. Subsequently, 29 of the patients underwent computed tomography and 16 underwent magnetic resonance imaging. The location and structure of the masses as well as their relationship to the surrounding structures were assessed. Anatomic confirmation and histopathologic diagnosis of the mediastinal masses by surgical resection and biopsy was available for all patients. Transesophageal echocardiography was more accurate than transthoracic echocardiography in detecting mediastinal masses (90% versus 73%), in identifying their structure (100% versus 90%), and in evaluating their relationship to contiguous organs (89% versus 81%). No complication was observed during the examinations. Computed tomography correctly diagnosed the location, structure, and relationships in all patients but one; magnetic resonance imaging correctly evaluated the mediastinal masses in all 16 patients. Our study suggests that transesophageal echocardiography is a valuable and safe complementary method of evaluating mediastinal masses. Moreover, this technique allows the obstruction of vessels and heart cavities, valve regurgitation, and right and left ventricular function to be easily assessed.
