Application of computed tomography in differential diagnosis of radiographic opacities in the lower thorax and upper abdomen.

The differential diagnosis of radiographic homogeneous opacities in the lower thorax and upper abdomen is very often a dilemma for radiologists. Recently we have encountered the following 8 cases in which the correct radiologic diagnoses (confirmed pathologically) were made only by computed tomography: pyogenic liver abscesses (2 cases), subphrenic hematoma, pancreatitis with pseudocyst, adrenal cortical carcinoma, ovarian carcinoma with liver metastasis, lower lobe pulmonary infarction, and metastatic breast cancer in the peri-esophageal region. The CT findings displayed not only the anatomic location and extent of these lesions but also the unique characteristics of many of the pathologic processes that produce these otherwise nonspecific radiographic opacities. It is our purpose here to demonstrate the CT findings in such patients and to advocate CT study as a very effective diagnostic modality in those patients who present with radiographic homogeneous opacities in the lower thorax and upper abdomen.

Plain film findings of hydropneumoperitoneum.

Abdominal radiographs of 11 patients with hydropneumoperitoneum were reviewed. The centrally located air collection was noted in nine of the 11 patients. In the other two patients with a large amount of fluid in the pelvis, the air bubble was located in the upper abdomen. In two patients, the edge of the centrally located large air bubble was ringed by a number of small bubbles. The falciform ligament was demonstrated in five. Air-fluid levels were seen in the upper abdomen in six patients in whom upright films of the abdomen were obtained. Hydropneumoperitoneum should be suspected in supine abdominal radiographs when one recognizes a large air collection with or without surrounding small air bubbles.

Tension hydrothorax: roentgenographic characteristics and pathogenetic consideration.

We have described a 24-year-old diabetic woman with rapidly developing left-sided tension hydrothorax. The pleural effusion was characterized by high contents of protein and glucose. The chest roentgenogram exhibited massive pleural effusion, prominent air bronchograms, mediastinal shift, and diaphragmatic inversion. Prompt thoracocentesis proved to be life-saving.

Nonobstructive coarctation.

Roentgenographic studies, including plain chest roentgenography, thoracic aortography, and coronary angiography, were performed in seven adult patients with nonobstructive coarctation, a congenital deformity of the upper thoracic aorta. The chest roentgenographic findings were compared with those of ten patients with obstructive coarctation studied during the same period. A great similarity was found in the morphology and associated lesions of these two conditions, which supports the idea that nonobstructive and obstructive coarctation are stages of the same disease. Patients with nonobstructive coarctation had a more prominent aortic arch, and the indentation in the thoracic aorta was higher than in patients with obstructive coarctation. In addition, patients with nonobstructive coarctation had no rib notching on plain chest roentgenograms. Angiographic evaluation in patients with nonobstructive disease demonstrated the anatomic lesion, the absence of collateral circulation, and the commonly associated anomalies of the aortic valve.

Osteosclerosis (punctate form) in multiple myeloma.

Generalized punctate and nodular osteosclerosis associated with multiple myeloma is reported with review of the literature and differential diagnoses. This patient differs from some others reported earlier in the absence of any recognized osteolytic lesions either during life or at autopsy.

Primary hemangiopericytoma of lung: radiography and pathology.

Two cases of primary hemangiopericytoma of the lung are reported. The massive tumors had radiographic features of round or oval contour, homogeneous opacity, well circumscribed smooth outline without calcification, and no compression of the surrounding lung tissue. They were rather homogeneous histologically, well encapsulated, and centrally located, but extended peripherally by replacement, instead of compression, of the pulmonary parenchyma. Review of the literature about 34 other cases suggests these are the usual characteristics of primary hemangiopericytomas of the lungs.

Pitfalls in ultrasonic detection of pleural fluid.

This is a report of proven massive infiltration of Hodgkin's disease of the lung with correlative sonographic, roentgenographic, and pathologic findings. Special emphasis is placed on the difficulties in distinguishing pleural fluid from massive tumor infiltration of the lung by Hodgkin's disease.

Computed tomographic diagnosis of pseudoascites (floating viscera syndrome).

Two cases of excessive fat deposition in the abdomen, confused clinically as massive ascites, are reported. Computed tomography (CT) has proven useful in making a definitive diagnosis of fat deposition in the abdominal and retroperitoneal space and has made further clinical studies unnecessary. No prior cases of pseudoascites (floating viscera syndrome) have been reported in the radiologic literature despite the specificity of CT diagnosis.

Pulmonary consolidation associated with infusion of a glucose-insulin-potassium solution in acute myocardial infarction.

From 1972 to 1975, we have observed seven patients with localized pulmonary consolidation distal to the tip of a Swan-Ganz catheter. These seven instances occurred in a population of over 300 patients receiving a hypertonic solution of glucose, insulin, and potassium for acute myocardial infarction. In four patients the glucose-insulin-potassium solution was instilled directly into the right pulmonary artery from the tip of the Swan-Ganz catheter. In the subsequent three patients the solution was administered via the right atrial port and thus perfused the entire pulmonary vascular bed. The roentgenographic appearance of this localized pulmonary consolidation is indistinguishable from infarction caused by pulmonary thromboembolus or wedging of the catheter.
