[Central lung embolism in chronic interstitial pneumopathy].
An 80 year old patient with known interstitial pneumopathy of unknown etiology was hospitalized because of acute onset and rapid deterioration of dyspnea at rest within days. A foregoing neurologic investigation including CT and EEG because of prior syncopes and cramp attacks had not revealed pathologic findings. Thorax X-ray at admission showed homogenous loss of transparency on the left side, calcified basal plaques on both sides and prominent central pulmonary vessels with jumping caliber. A punctate of the leftsided pleural effusion revealed lymphocytic exsudate, normal pH, low glucose and an elevated LDH. The patient died shortly after a collapse at a bowel visit and pulmonary embolism was suspected in accordance to results from arterial blood gas analysis, ECG and chest X-ray. Neurologic symptoms could be explained by recurrent pulmonary embolism. Pleural plaques together with the punctate suggested a malignant etiology. A mesothelioma was taken into consideration, although there were no anamnestic reports on an exposition to asbestos. Autopsy revealed almost complete central embolism of the left pulmonary artery with acute cor pulmonale thus confirming the clinical suspicion. The embolus showed components of different ages of origin. Besides bronchitic and emphysematous alteration histology of the pulmonary tissue revealed interstitial and septal fibrosis with focal tissue consolidation. In one giant cell a typical asbestos body was found (in 1 out of 10 sections). In spite of missing information on an exposition to asbestos an abnormally high exposition must be taken into consideration because of the finding of an asbestos particle in relation to the amount of tissue studied. Apart from interstitial fibrosis asbestos may also cause consolidation of pulmonary tissue. Histology of plaquelike lesions revealed mesothelioma of fibrous type. This finding supports the suspicion that a major part of the pulmonary lesions was due to exposition to asbestos.
