Dermoid Cysts and Teratomas of the Mediastinum With Unusual Features

Acquired pulmonary stenosis.

“…A benign teratoma caused pulmonary stenosis in 4 patients (Cases 2-5); in 3 of them no cardiac murmur had been heard at earlier examinations. Six cases of pulmonary stenosis due to a mediastinal teratoma or dermoid cyst have been previously reported (Rusby, 1944;Maier, 1948;Fry, Klein, and Barton, 1955;Eerland, 1962;Holstein et al, 1964;Gough et al, 1967). Thymoma. In Case 6 a benign thymoma appeared on serial chest radiographs in a patient with pulmonary tuberculosis, and subsequent examination showed signs of pulmonary stenosis.…”

Cardiovascular Complications in Malignant Thymoma

“…External constriction of the pulmonary artery has been reported in tuberculosis and bronchial carcinoma (9), in at least 36 cases of aortic aneurysm (lo), 5 of pericardial band (3), 2 of benign (9, 15) and 2 of malignant (8, 17) mediastinal teratoma, 1 case each of pericardial mesothelioma (20), sternal chondrosarcoma (3, mediastinal tumour of malignant lymphogranulomatosis (9) and lymphoblastoma (2), and in 1 case of benign (19) and 3 cases of malignant mediastinal thymoma (11,16,22). Compression of the superior vena cava is rather common in mediastinal tumours (16), also in thymoma (11, IX), which once has been reported to compress the ascending aorta too ( I l ) , and not very rarely may infiltrate the pericardium and myocardium (14) and the pulmonary parenchyma (11,16,18).…”

Acquired pulmonary stenosis

“…Prior to the series of cases reported by Gough, Gold, and Gibson (1967) and Seymour, Emanuel, and Pattinson (1968) only about a dozen single case reports had appeared in the literature. The tumours responsible for this syndrome included benign and malignant teratomas (Rusby, 1944;Maier, 1948;Fry, Klein, and Barton, 1955), lymphatic cyst (Wood, 1956), Hodgkin's disease (Winter, 1958;Shaver, Bailey, and Marrangoni, 1965), pericardial mesothelioma (Waldhausen, Lombardo, and Morrow, 1959), and lymphoblastoma (Babcock, Judge, and Bookstein, 1962).…”
