The changing epidemiology of tuberculosis and other mycobacterial infections in the United States: implications for the radiologist.

Diseases consequent to infection with mycobacterial organisms, such as Mycobacterium tuberculosis and other mycobacterial species, remain a significant health problem in the United States. Over the past decade several new factors have amplified this problem, the most significant of which is the ongoing epidemic of infection with the human immunodeficiency virus. This review will discuss the changing epidemiology of mycobacterial disease and emphasize the significance of these changes to the radiologist.

Radiologic manifestations of adult tuberculosis.

Adult pulmonary tuberculosis commonly presents with radiographic findings of upper lobe cavitary opacities, in which case the correct diagnosis is usually suspected. However, other radiographic presentations of this disease in the adult include intrathoracic adenopathy, pleural effusion, lower lobe consolidation, a miliary pattern, and a solitary nodule. In these latter cases, tuberculosis may not be considered in the differential diagnosis. This article discusses the protean manifestations of adult pulmonary tuberculosis.

Pulmonary embolism: chest radiographic abnormalities.

The value of chest radiography in the diagnosis of pulmonary embolism has been investigated extensively. Although the chest radiograph seldom permits one to say whether embolism is or is not present, it is still an essential component in the evaluation of the patient with suspected pulmonary embolism. This article stresses the radiographic abnormalities that occur with pulmonary embolism and defines the role of the chest radiograph for evaluation of this disorder.

Computed tomography and magnetic resonance imaging in the diagnosis of pulmonary thromboembolic disease.

In selected cases CT and MRI may be useful for the evaluation of patients suspected of having central pulmonary emboli. In stable patients MRI appears to be superior to CT because no iodinated contrast medium is required. In evaluating critically ill patients CT is better because of its superior resolution, ability to assess changes in the lung parenchyma, and ease of patient monitoring.

Azygos continuation of the inferior vena cava masquerading as neoplasm.

The two cases we have reported demonstrate that dramatic enlargement of the azygos vein may occur in patients with azygos continuation of the inferior vena cava. Awareness of this phenomenon can prevent unnecessary procedures. The diagnosis should be established by dynamic CT scan.

Bronchogenic cysts.

Bronchogenic cysts are relatively uncommon congenital lesions. They may be detected on routine radiography in asymptomatic patients or may present with various manifestations, some of which may be life-threatening. Age at diagnosis ranges from infancy to late adulthood, with asymptomatic lesions occurring more often in older children and adults. Cysts may be located in subcarinal, paratracheal, hilar, paraesophageal and intrapulmonary sites. The chest radiograph is the primary diagnostic study, with computed tomographic scans of the chest providing more definitive evaluation. Despite some controversy, surgery is considered the treatment of choice, even in the asymptomatic patient.

CT diagnosis of right hemothorax secondary to ruptured thoracoabdominal aneurysm: case report.

The development of a right hemothorax as the result of a ruptured thoracoabdominal aneurysm is an uncommon and usually fatal event. Survival depends upon an accurate diagnosis and prompt surgical intervention. We present a case of a ruptured thoracoabdominal aneurysm into the right chest that presented as opacification of the right hemithorax and hypotension. An early CT scan provided the correct preoperative diagnosis, although the patient did not survive.
