Radioclinical Profile of Eosinophilic Lung: A Case Series.

In this study, we present findings from an analysis of 17 patients diagnosed with eosinophilic lung disease, with a majority (64.70%) being male. The average age of the patients was 54 ± 13.22 years. A history of uncontrolled asthma was noted in nine cases. The clinical picture was characterized by persistent dyspnea and cough. Blood hypereosinophilia was present in all cases, with a median of 1770 cells/ul. Two patients had a pulmonary eosinophilia greater than 25%. Radiological findings were consistent with diffuse bilateral ground-glass opacities or areas of consolidation in the majority of cases. The main etiologies identified were chronic eosinophilic pneumonia (12 cases), followed by eosinophilic granulomatosis with polyangiitis (3 cases), idiopathic hypereosinophilic syndrome (1 case) and drug-induced hypereosinophilia (1 case). All patients were treated with systemic corticosteroids, with the addition of immunosuppressive therapy necessary in three cases. Notably, five relapses were recorded after corticosteroid therapy was stopped.

Variable Expression Common Immune Deficiency: A Report of Five Cases.

We present five cases of common variable immunodeficiency (CVID), comprising three women and two men with a mean age of 23.8 ± 9.2 years. All our patients suffered from recurrent bronchopneumonitis, with complications of purulent pleurisy in two cases, requiring decortication in one case, and resulting in bronchiectasis in three cases. Digestive tract infections were observed in four patients, while two patients presented with ENT infections. One case was complicated by bacterial meningitis. All patients presented with global hypogammaglobulinemia, with CVID and granulomatous manifestation in one case. Treatment consisted of monthly immunoglobulin infusions.

Post-tuberculosis fibrosing mediastinitis: A report of 3 cases.

Fibrosing mediastinitis is a rare entity generally caused by granulomatous disease. Most cases develop as a complication of histoplasmosis. Association with tuberculosis has been rarely documented. We report the case of 3 young patients who presented with superior vena cava syndrome several years after treated tuberculosis. Biological, radiological, and histological investigations led to the diagnosis of fibrosing mediastinitis.

Pseudotumor pulmonary sarcoidosis: A case report.

Sarcoidosis is a benign multisystem granulomatosis of unknown etiology. The mediastino-hilar sphere is a preferred site for the disease. It can sometimes reveal a confusing pseudotumoral presentation, constituting a diagnostic trap to be considered. We report the case of a 56-year-old woman whose lesional process rapidly resolved after 2 months of corticosteroid therapy.

Hydatid pulmonary embolism secondary to a right ventricular hydatid cyst: A case report.

Hydatid pulmonary embolism is an exceptional but serious condition. It complicates the rupture of a hydatid cyst in the venous return circulation, often of hepatic origin, or the endo-cavitary rupture of a hydatid cyst in the right heart. We report the case of a young patient with hydatid pulmonary embolism revealed by recurrent episodes of hemoptysis.

Thirteen Cases of Pulmonary Pneumocystis in HIV-Negative Patients.

We report 13 cases of pulmonary pneumocystis (PCP) in human immunodeficiency virus (HIV)-uninfected patients. Of eight males and five females, with a mean age of 55 years, one had breast neoplasia, two had common variable immunodeficiency (CVID), one had an autoimmune disease "Goodpasture's syndrome", and one had idiopathic fibrosis (nonspecific interstitial pneumonia/fibrosis (NIP)) undergoing prolonged corticosteroid therapy for two years, with no known immunosuppression in the remaining cases. The clinical picture was characterized by constant dyspnea and severe hypoxia in 11 cases. Lymphopenia was present in nine cases with an average rate of 920.76 elements/mm3. The diagnosis was confirmed by isolation of Pneumocystis jirovecii (PCJ) from induced sputum, except in two cases where analysis of bronchoalveolar lavage (BAL) fluid was required. With trimethoprim/sulfamethoxazole (TMP/SMX) and corticosteroid therapy, the course was favorable in all cases. Prophylactic treatment was indicated in three cases.
