[Echinococcosis of the rib with epidural extension]. / Kyste hydatique costovertébral : pathologie bénigne ou maligne ?

Osseous hydatidosis, especially when located in the rib, is a very rare disease. Less than 50 cases of costal echinococcosis have been reported in the literature to date. The authors report a case of echinococcosis of the rib with epidural extension in a 76-year-old patient presenting paraparesis. In addition, the patient presented a large posterior and thoracic soft tissue mass measuring about 30 centimetres in diameter. A chest x-ray, a CT thoracic scan and an MRI of the dorsal spine were performed. The imaging suggested echinococcosis of the rib with epidural extension. The cyst was completely resected. Histopathology of the resected specimen confirmed the diagnosis of echinococcosis. The patient died due to postoperative complications. Accurate presurgical diagnosis allows for appropriate management and helps eradicate the disease. This also prevents the dissemination of parasites and further complications.

Congenital cataract etiology.

AIM: Our purpose is to study the aetiologies of congenital cataracts, and to establish an approach to decision making of etiological diagnosis. METHODS: We included 85 children in a cross sectional study. The mean age was 4.5 years. These patients underwent a complete ophthalmologic and paediatric examination, and etiological investigation. RESULTS: An aetiology of congenital cataracts was found in 62.5% of cases. Hereditary was the most common cause, it constituted 42.3% of etiologies. Among these cases 77.7% were autosomal recessive. 16.4% of congenital cataracts were associated with general diseases or dysmorphology syndromes. Metabolic diseases and intrauterine infections were found in 7 % and 4.7% of cases respectively. CONCLUSION: Heredity remains the most common etiology of congenital cataracts.

[Broncholithiasis]. / Broncholithiase.

INTRODUCTION: Broncholithiasis is defined as the presence of calcified material in the bronchial lumen. The aim of our work was to study the clinical, radiological and therapeutic aspects of broncholithiasis. OBSERVATIONS: We report the histories of 6 patients identified over 14 years (1990-2004). They included 4 men and 2 women with an average age of 50 years. A past history of pulmonary tuberculosis was found in 2 cases. The presenting symptom was haemoptysis in 4 patients. Fibreoptic bronchoscopy was performed in all patients and broncholiths were found in two. Thoracic CT scan was performed in 5 patients and in 3 showed hilar and parenchymal calcification, suggesting the diagnosis of broncholithiasis. The diagnosis was confirmed in 2 patients by bronchoscopy, in 2 others by surgical biopsy and in the remaining 2 by the CT appearances. Three patients were operated on: 2 for diagnosis and the third for haemostasis. Pulmonary tuberculosis was discovered in 2 patients, one by culture and the other by surgical biopsy. The outcome was satisfactory in all cases. CONCLUSIONS: Broncholithiasis presents a problem of differential diagnosis from other pulmonary pathologies on account of misleading clinical, endoscopic and radiological features.

[A rare complication of antineoplastic BCG therapy: pulmonary tuberculosis]. / Une complication rare de la BCG therapie antineoplasique: la tuberculose pulmonaire.

Local treatment with intra vesical BCG for bladder carcinoma have few complications. Pulmonary side effects are rare, like interstitial pneumonitis. We report a case of a 77-year-old man, treated with BCG for bladder carcinoma who developed illness and tumoral chest-X-ray opacity. Mycobacterium tuberculosis bovis was isolated in culture and 2 years after in sputum. Physio pathologic mechanism of pulmonary features remains controversial, however this case suggest that lung lesions can be result of an infection process.
