High-resolution CT appearance of diffuse alveolar septal amyloidosis.

Primary diffuse alveolar septal amyloidosis.

The case is reported of a 61-year-old man with primary diffuse alveolar septal pulmonary amyloidosis. Amyloid infiltration of the heart and other organs was also observed. The clinical findings and laboratory investigations reveal features characteristic of defective gas transfer with pulmonary oedema due to left ventricular failure from myocardial involvement.

Pulmonary Diffuse Alveolar Septal Amyloidosis

Primary diffuse alveolar septal amyloidosis with multiple cysts and calcification.

We report an extremely rare case of primary diffuse alveolar septal amyloidosis associated with multiple cysts and calcification. Development of multiple cysts may have resulted from fragile alveolar walls, as a consequence of amyloid deposition both on alveolar walls and around capillaries.

Multiple nodular pulmonary amyloidosis. A case report and comparison with diffuse alveolar-septal pulmonary amyloidosis.

A case of multiple nodular pulmonary amyloidosis in a 54-year-old Caucasian man is presented. Discrete symptomless radiodensities had developed in this patient's lungs within a period of three years, leading to a suspicion of a neoplastic process. The amyloid nature of these nodules was demonstrated by biopsy. In this case, as in others previously reported, there was no evidence of systemic dis...

High-resolution CT of alveolar filling disorders.

Airspace filling process is characterized on CT by the presence of one or more fairly homogeneous areas of consolidation with little or no volume loss. The consolidation may be segmental, subsegmental, lobular, or acinar (10 mm or less in diameter). Poorly defined centrilobular nodules may be associated. The margin of the consolidation usually is poorly defined except in the areas in which the ...
