[Disseminated tuberculosis in non-immunocompromised host: three case reports].

INTRODUCTION: Disseminated tuberculosis, i.e., tuberculosis involving lung, liver, spleen, bone marrow and lymph nodes is rare (2.8%), particularly when immunocompromised diathesis is lacking. EXEGESIS: We report three cases of disseminated tuberculosis confirmed by bacteriology or histology, which occurred in non-immunocompromised patients. Disease evolution under antituberculous treatment was favorable in two cases and fatal in the third one. CONCLUSION: Disseminated tuberculosis must be suspected when miliary pulmonary lesions are associated with hematologic abnormalities, even in non-immunocompromised host. Early treatment is mandatory to avoid fatal outcome.

[Post hydatid chronic cor pulmonale].

We report a case in a patient aged 28 admitted with haemoptysis and dyspnoea. The chest x-ray showed multiple disseminated hydatid cysts throughout the lung fields. Computerized tomography and an abdominal echo found a hydatid cyst of the liver in contact with inferior vena cava which was probably responsible for the secondary pulmonary dissemination. Subsequently there was a multiplication of the lesions with rupture and infection of several cysts. After two years the disease progressed into chronic respiratory failure with the appearance of chronic cor pulmonale. The respiratory state rapidly worsened with several episodes of cardiorespiratory failure. Death occurred six months after the appearance of CPC.

[Pseudotumor presentation of pulmonary sarcoidosis apropos of 3 cases].

Pseudotumoral manifestations in the thorax is an unusual presentation of sarcoidosis. We report three such cases including two which mimicked pulmonary metastases with a classic image of multiple lesions in two women aged 31 and 30 years. In the third case, a 51-year-old male smoker had an opacity in the upper left lobe on chest x-ray then developed endobronchial hemorrhage suggestive of a primary bronchogenic cancer. In most cases, bronchial or transbronchial biopsies are sufficient for diagnosis. Surgical biopsy may be required however to eliminate the possibility of tumoral proliferation or an other granulomatous etiology.

[Primary localized bronchopulmonary amyloidosis].

A 56-year-old patient with an uneventful history was hospitalized for investigation of recent dypnea. The physical examination was normal and chest X-ray showed localized interstitial lesions in the upper right lobe. Endoscopy showed evidence of diffuse infiltration of the bronchial mucosa and narrowing of the lumen. Transbronchial histology showed evidence of bronchopulmonary amyloidosis. There were no signs of extrapulmonary localizations. Search in other organs was negative demonstrating the primary nature of the lung disease. Primary bronchopulmonary amyloidosis is rarely encountered.

[Standard radiological characteristics of thoracic sites of tuberculosis in patients with AIDS in a Tunisian population].

Aspects of tuberculosis on the standard chest X-ray in a population of 18 AIDS patients in Tunisia were examined. The diagnosis of pulmonary tuberculosis was confirmed in all cases with bacteriology tests. Diffuse lesions of the parenchyma predominated contrasting with the exceptional nature of cavernous formations. Localized infiltrations were infrequent and intrathoracic node enlagement was rare. Cases with no abnormal radiological signs were also seen in advanced HIV infection. Such atypical cases, in agreement with data in the literature, would be explained by immunoradiologic correlation. Thus it is necessary to search for the tuberculosis bacilli in all patients with HIV infection whatever the aspect on the standard chest X-ray.
