[Hydatid pulmonary embolism. Two case reports]. / Embolies pulmonaires hydatiques. A propos de deux cas.

Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid heart cyst or the opening of a visceral hydatid cyst (often in the liver) into the venous circulation. We report two cases of hydatid pulmonary embolism following rupture of a hydatic cyst in the right ventricle. One case progressed to chronic cor pulmonale. We examine the pathophysiological mechanisms as well as the clinical, therapeutic and evolutive aspects.

[Oral desensitization to antitubercular agents]. / Désensibilisation orale aux anti-tuberculeux.

We report a case of hypersensitivity reaction to majors antituberculosis drugs. We have successfully performed oral desensitization to "Rifater *". We present our protocol that we compare to those proposed in the literature.

[Middle lobe syndrome: apropos of 5 cases]. / Le syndrome du lobe moyen: à propos de 5 cas.

We present 5 cases of middle lobe syndrome. We discuss the etiologic aspects. Fibroptic bronchoscopy must be systematic. Treatment is conservative or surgical.

[Endo-bronchial lipoma. Apropos of a case]. / Lipome endo-bronchique. A propos d'un cas.

We report a case of an endobronchial lipoma on a 63 year-old woman, treated surgically. A literature review allows us to show the importance of fiberoptic bronchoscopy and computerized tomography in the diagnosis of this kind of benign tumors. The different aspects of treatment with recent progress represented by endoscopic resection are studied.

[Pneumomediastinum in dermatopolymyositis]. / Pneumomédiastin au cours d'une dermatopolymyosite.

The authors report the occurrence of a pneumomediastinum occurring in a young female aged 25 who had already been under treatment for 3 years for dermatomyositis and who had a pulmonary involvement with fibrosis. This association did not seem fortuitous. The pneumomediastinum would be due to a cystic degeneration of the fibrosis producing "pseudoblebs".
