Vacuole sign and nodule sign in early peripheral bronchogenic carcinoma. Diagnostic value and pathologic correlation.

We analyzed the radiological and pathological characteristics of 30 peripheral lung masses 1.5-3 cm in diameter. We describe the vacuole and the nodule sign. Retrospective examination of 100 conventional tomograms of peripheral pulmonary masses and comparison with the histological diagnoses allowed us to determine the usefulness of these two signs in differentiating small peripheral bronchogenic carcinomas from tuberculomas.

CT of pulmonary edema.

We describe our experience with CT of the chest in the diagnosis of pulmonary edema due to congestive heart failure, overhydration, renal failure, or increased capillary permeability. CT is able to detect acinar shadows and air-bronchograms more clearly than conventional radiography. Specific pattern of distribution of edema can be imaged in cross-section due to the elimination of superimposition of structures. In patients with adult respiratory distress syndrome, CT can detect microcystic transformation of the lung, which indicates a worse prognosis. Complications of ARDS, not always clearly visible on bedside chest radiographs, can be identified with CT.

[Roentgen pathology of blunt bronchial injuries].

We present eight patients with bronchial injuries. The pertinent radiographic findings were subdivided into: (1) signs pertinent to the bronchial tree; (2) signs due to airleak; (3) signs made in the subtended lung. The radiologist plays an important role in the early diagnosis of this severe injury.

[The right postpneumonectomy syndrome].

Two patients with a so-called right-sided postpneumonectomy syndrome are described. The syndrome results from a marked mediastinal shift towards the vacant hemithorax, primarily after a pneumonectomy performed in early childhood. The trachea is compressed by the aortic arch and distorted by the mediastinal shift. The left main bronchus is compressed between the left central pulmonary artery and the descending aorta. This can result in tracheobronchomalacia and recurrent pneumonia in the remaining lung.

[CT diagnosis of cystic hygroma].

We present five patients with cystic hygroma: the CT features are presented. It occurs primarily in the region of the neck. Occasional involvement of the axilla, the chest wall and the mediastinum is possible.
