[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.

[Metastatic benign leiomyoma in a 46-year-old woman].
Chest X-ray in a 46-year-old woman with a history of hysterectomy for a uterine mass revealed a nodular opacity measuring 3 cm. Computed tomography identified 3 other nodules. Histology examination of the lung lesions identified the same configuration as that of the hysterectomy specimen performed two years earlier: benign metastatic leiomyoma. Approximately 40 cases have been reported in the literature.

[Thymolipoma. A case report].
Thymolipoma is an uncommon benign tumor of the thymus. Asymptomatic, it is an incidental discovery. Pathogenesis remains controversial. We report a new case in a 36-year-old woman that was discovered on a chest x-ray ordered for pneumonia. The MRI findings suggested the diagnosis which was confirmed at the pathology examination of the surgical specimen.

[Endobronchial pulmonary rhabdomyosarcoma. A case report].
We report a case of pleiomorphous pulmonary rhabdomyosarcoma observed in a 64-year-old patient with no history of soft tissue tumor. The tumor was found extending into the right lower and middle lobes. The intra-parenchymatous extension protruded into the middle lobular bronchus and was prolonged by a 4 cm polyp. The polyp extended up to the carina and reached the contralateral common bronchus. Outcome was fatal after surgery performed in an emergency setting due to asphyxia. Explorations could not be continued to determine the primary or secondary nature of the tumor. An intraparenchymatous endobronchial localization is uncommon. Primary rhabdomyosarcoma is generally a purely intra-parenchymatous tumor. The endobronchial localization has been described before but is very exceptional. This localization would also be exceptional for secondary rhabdomyosarcoma mimicking a primary malignant tumor. The histology study revealed an undifferentiated pleiomorphous tumor. Immunohistochemistry provided the final diagnosis.

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.

The Carbomedics prosthetic heart valve: four year follow-up in 100 patients.
From December 1988 to December 1991, 100 patients underwent valve replacement with a Carbomedics bileaflet valve in our institution (55 aortic valve replacements, 28 mitral valve replacements, and 17 double valve replacements). Fifty-nine percent were males. Mean age was 55.7+/-12.3 years. Fifty eight percent of patients were in NYHA Clinical status III or IV. Operative mortality was 3% (3/100). All patients but one were followed up for an average of 2.8 years after their operation and total follow-up was 280 patient years. At the time of the study, more than 80% of patients were in NYHA class I or II, 34% were in atrial fibrillation and 100% of patients received anticoagulation treatment. There were 3 late deaths. After 4 years, the actuarial survival rate was 94%+/-5%. No patients died of valve-related causes. Valve-related complications included 2 thromboembolic episodes (0.7%-patient-year), 8 anticoagulant-related complications (2% patient-year), and one reoperation (0.3% patient-year). After 4 years, freedom from thromboembolic complication was 96%+/-4%, from endocarditis was 100%, from reoperation was 99%+/-1%, and from anticoagulant-related complications was 93%+/-5%. We conclude that the 4-year results compare with other bileaflet valves. More follow-up and larger studies are mandated to give definite conclusions.
