[Thoracic involvement in Behçet's vasculitis].

Thoracic involvement of Behcet's disease is unusual but serious. It is related to the well known vascular tropism of the disease. It may involve the superior vena cava, pulmonary arteries, aorta and subclavian vessels. Imaging is useful for diagnosis and assess the degree of thoracic involvement. CT scan and MRI are obviously more accurate than angiography. The spectrum of thoracic manifestations of the disease is presented based on a review of 22 cases.

Tracheobronchopathia osteochondroplastica presenting as a respiratory insufficiency: diagnosis by bronchoscopy and MRI.

Tracheobronchopathia osteochondroplastica (TO) is a rare benign disorder affecting the trachea and occasionally the bronchi. We report a case of TO presenting as a respiratory insufficiency. Chest radiograph revealed an irregular narrowing of the intra thoracic trachea and a parenchymal consolidation of the left lower lobe. Magnetic resonance examination of the chest showed a diffuse irregular thickening of the trachea and central bronchi, which had an intermediate signal intensity with punctiform low signal intensity suggesting calcifications and no contrast enhancement. The diagnosis was confirmed by bronchoscopy and biopsies.

[Ultrasonographic, CT, and MRI findings of chest wall hydatidosis].

The chest wall is an uncommon localization for hydatid disease even in countries where echinococcosis is endemic. Only isolated sporadic cases have been reported in the literature. We reviewed retrospectively 15 patients who underwent surgery for chest wall hydatid disease. Various imaging techniques were used for diagnosis of our cases. These included chest radiograph, thoracic ultrasonography, computed tomography and magnetic resonance imaging. Hydatid cyst involved soft tissues (n=5), ribs and vertebrae (n=5), ribs (n=4) and sternum (n=1). Imaging techniques were of value for diagnosis (radiographs and sonography) and for evaluation of the extent of involvement (CT and MRI). Chest wall hydatidosis requires surgical treatment but recurrence is frequent.

[Value of CT scanning in the investigation of thoracic sarcoidosis].

INTRODUCTION: Sarcoidosis is a systemic disease of unknown aetiology that includes a pulmonary or mediastinal component in 90% of cases. The aim of this study is to clarify the contribution of thoracic CT scanning in the diagnosis and differential diagnosis of sarcoidosis and its role in the follow-up and the evaluation of the activity of the disease. METHODS: It is a retrospective study of 39 patients with histologically confirmed sarcoidosis. All patients had one or more thoracic CT scans. RESULTS: The most common parenchymatous lesions were lymphatic micronodules and peri-bronchovascular thickening. The right paratracheal chain and the hilar nodes were the most frequently involved. CONCLUSIONS: The CT scan is better than the chest x-ray at studying the parenchymal lesions and lymph node involvement in sarcoidosis. It helps in the differential diagnosis of sarcoidosis and other granulomatous disorders, especially tuberculosis. It also allows follow up of patients for the detection of complications, particularly fibrosis. Its role in the assessment of disease activity remains controversial.

[Tuberculosis of the lung bases].

Tuberculosis of the lung bases is a rare condition that can mimic pneumonia, bronchial carcinoma, lung abscess or bronchiectasis. Diagnostic delays, that can lead to serious complications not amenable to surgical resection, are often the result of repeatedly negative bacteriological examinations. We report a series of 10 cases of tuberculosis of the lung bases collected between 1993 and 1998 that were examined by computerised tomography. The chest x-ray most commonly showed a heterogeneous opacity. On the CT scan this corresponded with an area of alveolar consolidation which, when it was associated with centrilobular micronodules and cavitated nodules and masses, suggested the diagnosis of basal tuberculosis. Indeed the absence of apical lesions and the frequency of involvement of mediastinal and bronchial lymph nodes support the hypothesis of bronchial dissemination of the bacilli from tuberculous nodes. This explanation is supported by the high incidence of endobronchial lesions found at bronchoscopy in this form of tuberculosis.

Hydatid disease of the liver with thoracic involvement.

Hydatidosis, caused by Echinococcus granulosus, is an endemic parasitic disease in Mediterranean countries. The most frequent anatomic locations are liver and lung. Intrathoracic rupture of hydatid cysts situated in the hepatic dome is a serious complication resulting in damage to the pleura, pulmonary parenchyma, and bronchi. From January 1984 to December 1997 we operated on 40 patients with intrathoracic rupture of a hepatic hydatid cyst. Chest roentgenograms showed a shadow of varying size at the base of the hemithorax. Hepatic and thoracic ultrasonography was performed in all cases. The diagnosis of intrathoracic rupture of a liver cyst was confirmed preoperatively in 30 of the 40 cases. Posterolateral thoracotomy was performed in all patients. This transthoracic approach allowed adhesiolysis and treatment of the pleural lesions, pulmonary lesions, and hepatic cyst. Treatment of the diaphragmatic gap is easily done. We performed 15 lobectomies, 10 wedge resections, 16 decortications, and in one patient simple drainage of a voluminous pleuropulmonary and hepatic purulent hydatic collection. The postoperative course was uneventful in 26 cases, but 14 patients had complications, from which 3 patients died. The therapeutic approach depends on ultrasonographic findings. We believe ultrasonography to be the best examination for assessing biliary, hepatic, diaphragmatic, and pleuropulmonary lesions. When an intrathoracic collection is present, thoracotomy must be performed and is sufficient if the biliary tract is safe. An abdominal approach is necessary when biliary duct drainage is required, and it may be sufficient in cases of direct rupture into the bronchi.

[Radiological and clinical aspects of bronchogenic lung cysts: 4 case reports].

Bronchogenic lung cysts are exceptional. We report four cases which raised a problem of differential diagnosis. Our patients included four women and a young boy (age range 12 - 36 years). The first patient consulted for bloody purulent sputum in a context of an infectious syndrome. The second patient had lower right-sided chest pain. The cyst was a fortuitous discovery in the other two cases. In one case, the chest x-ray disclosed a thin-walled cavity of the upper right lobe, confirmed on the CT scan which also evidenced intracavitary partitions. In two other cases, the chest x-ray showed a liquid-filled opacity (one in the lower right lobe and the other in the upper right lobe) and no further specificity on the CT scan. In the last case, a liquid-air cavity was evidenced. Upper right lobectomy was performed for the case with an air-filled cavity and tumorectomy for the other cases. Pathology reported bronchogenic cyst in all cases. The radiological and clinical presentations observed in patients with bronchogenic lung cysts, with or without tracheobronchial communication, are polymorphous, often raising problems of differential diagnosis.

[Pulmonary embolism of hydatic origin].

BACKGROUND: The right ventricle is an exceptional localization for hydatic cysts. There is a risk of hydatic embolism and chronic or acute cor pulmonale. CASE REPORT: A 63-year-old-man with an uneventful history was hospitalized for dry cough, exercise-induced dyspnea and bloody expectorations which had developed over the previous year. Multiple and bilateral opacities were visualized on the standard chest x-ray and the right border of the heart showed a bulge in the middle portion. Signs of right-sided hypertrophy were seen on the ECG. Imaging findings led to the diagnosis of multiple organ hydatiasis involving the lung, the liver the mediastinum and a ruptured hydatic cyst in the right ventricle. The cavogram revealed defect images in the superior vena cave and the pulmonary angiogram confirmed the diagnosis of hydatic embolism. Medical treatment was given but the patient died 8 months after diagnosis. DISCUSSION: Hydatic pulmonary embolism generally occurs after rupture of a hydatic cyst in the right ventricle or due to venous migration of daughter vesicles to the right heart then the pulmonary artery. Clinical manifestations are not specific although hemoptisy is the most frequent sign. Positive diagnosis, guided by echocardiographic findings, is based on the pulmonary arteriogram. Prognosis is particularly poor and depends of the patient's general status as well as the number and size of the embolized vessels. Survival rate is poor. Open heart surgery is indicated in localized forms.

[Multiple hydatid cysts of the thigh: the role of magnetic resonance imaging].

Hydatid cysts of the thigh are uncommon in our country despite a high frequency of hydatic disease which is estimated to affect 5.33% of the general population. Diagnosis is usually made late in the clinical course. Ultrasonography, CT scan and magnetic resonance imaging are the most helpful diagnostic tools. We report a case of a 76-year-old female smoker who had undergone surgery for a hydatic cyst of the right lung at the age of 56 years. In June 1997, the patient was admitted for decompensation of chronic obstructive lung disease. Physical examination revealed a 6 cm painless mass in the right thigh which had developed progressively over the last year. Ultrasonography showed multiple hydatic cysts. Magnetic resonance imaging confirmed the diagnosis, showing interconnected multivesicular cystic formations. Medical treatment was given due to respiratory failure and patient refusal of a surgical procedure.

[Tuberculosis of the thoracic wall. Presentation of 4 personal cases and review of the literature].

The thoracic wall is an uncommon localization for tuberculosis, accounting for an estimated 1 to 5% of all cases of bone and joint tuberculosis which themselves account for 15% of all extrapulmonary localizations. Four patients were hospitalized for tuberculosis of the thoracic wall. The first patient, aged 22 years, had sternal tuberculosis with multiple bone localizations. The second patient was 37 years old and had a cold abscess of the peristernal soft tissues with several other bone localizations devoid of clinical manifestations. A third 37-year-old patient had a cold intercostal abscess revealed by a mass in the upper left quadrant of the left breast. In the last patient, 50 years old, tuberculosis of the ribs was associated with a cold tumor of the knee. Together with cases reported in the literature, these observations demonstrate the difficult diagnostic situation presented by tuberculosis of the thoracic wall. Treatment is based on long-duration multi-drug therapy. Surgical resection is rarely indicated. Cure was achieved in our four cases.

[Pulmonary hyalinizing granuloma: review of two cases].

Pulmonary hyalinizing granuloma is a rare fibrosing nodular disease of the lung characterized by solitary or multiples pulmonary nodules. This report describes two cases of this rare disorder. MRI was available in one case. For the first case, the stability of the lesions and past history of retroperitoneal fibrosis suggested the diagnosis. For the second case, open lung biopsy was required for diagnosis. When multiple nodules are present, metastatic disease cannot be excluded and biopsy may be required. Evolution is usually benign but follow up is necessary.
