Pulmonary alveolar microlithiasis: CT findings.

We present five cases with confirmed diagnosis of pulmonary alveolar microlithiasis that illustrate the appearance of this rare chronic lung disease on conventional and high-resolution CT. Pulmonary alveolar microlithiasis is characterized by widespread intraalveolar calcification of both lungs. Conventional CT confirmed the inferior and posterior predominance of the lesions in four of our cases and showed an exceptionally high concentration of microliths in the subpleural parenchyma and along the bronchovascular bundles. High-resolution CT revealed a perilobular and bronchovascular distribution of the disease process at the level of the secondary pulmonary lobule. This pattern correlated closely with pathologic findings.

[X-ray computed tomography in venous pathology].

After presenting the tomodensitometric semiology of venous thromboses in various territories, the authors define its indications. It is essentially in deep territories, head, chest and abdomen that the CT-Scan is used to study and diagnose unrecognized thromboses as well as determine the venous repercussion of various neighboring ailments. The respective place of the CT-Scan, ultrasonography and various phlebographies is analyzed.

[Magnetic resonance in venous pathology].

After a brief and schematic reminder of the physical bases of I.R.M. in the study of blood vessels, the results and indications are presented in various venous territories: superior and inferior vena cava, hepatic, cerebral and peripheral veins. Venous and peri-venous diseases are simply emphasized. The advantages of the technique, multi-dimensional study without contrast nor radiation, are emphasized and compared with the drawbacks depending essentially on the cost and the length of the tests.
