Diverse roentgenographic manifestations of the rare pulmonary involvement in myeloma.

Roentgenographic manifestations of two cases of pulmonary involvement with myeloma were presented. One showed a nodular mass lesion extending from an extramedullary mediastinal plasmacytoma into the lung parenchyma while the other showed diffuse reticulonodular infiltrate by myeloma cells in association with alveolar septal amyloidosis. These two cases demonstrate the extreme variability of pulmonary involvement by myeloma, which can mimic a solitary tumor or an inflammatory infiltrate.

Radiographic evidence of calcification in pulmonary hamartomas.

Eight cases of solitary intrapulmonary hamartomas are presented to show the unusually high frequency of calcification (75%, six of eight cases) in this series. Possible contributory factors were high percentage of chondromatous variant (seven of eight cases), large size of the tumors, and use of computed tomography.

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.

Cardiovascular involvement by invasive thymomas.

We have observed 74 cases of thymoma from 1968 to 1974. Six cases of invasive (malignant) thymoma presented in an unusual fashion with signs and symptoms of cardiovascular disease and superior vena caval syndrome. The clinical, pathological, and roentgenographic features of these cases are presented. The literature concerning cardiovascular involvement by thymoma is reviewed and discussed.

Malignant hypertension as a cause of massive intestinal bleeding.

A forty-one year old man with a three year history of malignant hypertension developed massive rectal bleeding. A mesenteric arteriogram showed vascular changes compatible with necrotizing angitis. Histologic examination of the resected right hemicolon confirmed malignant hypertension as the cause of angitis.
