Carcinomatous involvement of the hilum and mediastinum: computed tomographic and magnetic resonance evaluation.

Magnetic resonance (MR) imaging and computed tomography (CT) were compared in 20 patients who had primary lung tumors, and the results were correlated with findings at surgery and pathologic evaluation. Both studies demonstrated a similar ability to detect hilar and mediastinal tumor. MR imaging detected more enlarged nodes in the mediastinum, but in several patients these enlarged nodes did not contain tumor. Consequently, MR imaging has a slightly higher false-positive rate in the evaluation of the mediastinum. Both modalities were highly sensitive, with specificity limited by the presence of enlarged benign lymph nodes in this series of patients.

The trachea: the blind spot in the chest.

This article emphasizes diagnostic importance of careful observation of the size, position, and luminal air column of the trachea in the interpretation of the chest roentgenogram. The changes described provide information about intratracheal lesions and help in localization and differential diagnosis of mediastinal masses.

Pulmonary metastases 15 years after removal of an alveolar soft-part sarcoma of the tongue.

Alveolar soft-part sarcoma is a distinct entity. The clinical course is protracted with survival up to 20 years, although the patients eventually succumb to their disease with distant metastases. Because of frequent local recurrences radical surgery is treatment of choice. A case of a 19 year old asymptomatic man with pulmonary metastases discovered 15 years after removal of a primary tumor from the tongue is reported and clinical, radiographic and therapeutic aspects of the disease are discussed.

Anterior mediastinal lymphadenopathy in sarcoidosis.

Several lymph node chains in the anterior mediastinum lie between the sternum and the trachea. On a lateral chest radiograph they form two distinct groups separated by the superior vena cava. One group projects anterior to the trachea and is formed by overlapping nodes of the anterior paratracheal and the left anterior mediastinal (prearterial) chains. The other is in front of the superior vena cava, composed of the right anterior mediastinal (prevenous) and horizontal chains. The position of these chains prevents them, even when enlarged, from being seen on posteroanterior chest radiographs or tomography: frequently they may not be appreciated on lateral chest films. Therefore lateral chest tomography is the best method to evaluate anterior mediastinal lymphadenopathy. With this technique, anterior mediastinal lymphadenopathy in sarcoidosis should be found more frequently than indicated in the literature.

Chest roentgenography as a window to the diagnosis of Takayasu's arteritis.

The chest roentgenographic findings in Takayasu's arteritis include widening of the ascending aorta, contour irregularities of the descending aorta, arotic calcifications, pulmonary arterial changes, rib notching, and hilar lymphadenopathy. The single most important diagnostic sign is a segmental calcification outlining a localized or diffuse narrowing of the aorta. The other signs may be suspicious or suggestive, but the diagnostic accuracy increases when several findings are present simultaneously.
