The silhouette sign and the inferior vena cava.

Pulmonary lesions causing obliteration of the normal inferior vena cava (IVC) shadow on the lateral radiograph are described. Retrocardiac mediastinal mass lesions and subpulmonic pleural effusions may also obliterate the IVC contour. Loss of the IVC shadow is an additional radiographic sign of right lower lobe collapse and frequently of disease involving the medial basal segment of the right lower lobe. This finding should be an indication that further investigation is needed to explain the loss of normal aeration.

Esophageal Achalasia

Antral and esophageal rimple: a normal variation.

The occurrence of fine antral and esophageal rimpling appears to be the result of contractions of the muscularis mucosa. The lack of persistence during distention is compatible with this conclusion. The folds have no pathologic significance.

Esophagus

Solitary neurofibroma of the trachea.

The patient was a 60-year-old white male who, for 18 months, had complained of a substernal wheeze on exertion, exertional dyspnoea and cough, and attacks of acute respiratory distress. There was no haemoptysis or dyshpagia and he was treated for bronchial asthma until bronchoscopy revealed the tumour which had not been recognized in plain chest films. He showed no evidence of a neurofibromatosis and apart from reduction in pulmonary function tests on a PO2 of 74, his laboratory tests were negative. There was no family history of neurofibromatosis. He underwent thoracotomy and a smooth rounded pedunculated tumour, 2.5 cm in diameter, arising from the posterior wall of the trachea, 3 cm above the carina was excised. He has had no tumour recurrence.

Humans

Osler revisited: an unusual cause of inversion of the diaphragm.

Osler described depression of the left hemidiaphragm and left lobe of the liver as a physical finding in some patients with pericardial effusion. Inversion of the left hemidiaphragm associated with a large pericardial effusion is an unusual, previously unreported complication. It may be a contributory factor in the production of unexplained dyspnea in some patients.
