TY - JOUR T1 - Mediastinal Teratoma With Pulmonary Involvement Presenting as Massive Hemoptysis in 2 Patients JF - Respiratory Care SP - 1094 LP - 1096 VL - 55 IS - 8 AU - Robert Fu-Chean Chen AU - Tzung-Hao Chang AU - Chi-Chu Chang AU - Chun-Nin Lee Y1 - 2010/08/01 UR - http://rc.rcjournal.com/content/55/8/1094.abstract N2 - Massive hemoptysis is described in many disease processes. However, a mediastinal teratoma is rarely considered in a patient presenting with massive hemoptysis. Since a mediastinal teratoma has no specific symptoms, its definitive diagnosis is difficult before surgical intervention. Flexible bronchoscopy can be diagnostic in cases of a mediastinal teratoma with involvement of the bronchial tree. We report 2 cases of hemoptysis caused by mediastinal teratoma with bronchial communication. ER -
