[Benign schwannoma: a case report about a uncommon localisation]. / Schwannome benin: a propos d'une localisation inhabituelle.

Schwannoma is a benign slow growing nerve sheath tumor which generally originates from cranial or spinal nerve roots. Peripheral nerve localisations are scarce. We report the case of a 76-year man who presented with a laterosternal chest wall mass located in the fourth intercostal space. Diagnosis of intercostal benign schwannoma was suggested by medical imaging and confirmed histologicolly upon surgical removal. Chest wall solitary schwannoma is exceptional. Our case is still more interesting by its peripheral localisation and late occurence following a chest trauma.

[Management of massive hemoptysis: current role of interventional endoscopy]. / Prise en charge des hémoptysies massives place actuelle de l'endoscopie interventionnelle.

Massive hemoptysis represent a very serious pathology and a vital threat for the patients. In spite of the availability of several therapeutical tools, the prognosis remains dark: mortality more than 60%. We expose here, the pathophysiological mechanisms of this severe complication and the main predisposing conditions and etiologies, to then approach the contribution of new endobronchial interventional treatments. The flexible endoscopy allowing only limited acts like the instillation of adrenalin and physiological solution at 4 degrees C, can in some cases contribute to probe or endobronchial catheter installation or intubation. The rigid bronchoscopy finds in massive hemoptysis a vast field of action and will make possible to better control the bleeding and to ensure the hemostasis: thermocoagulation, laser and cryotherapy aim at the same time stopping the haemorrhage and allow specific treatment. Their results are different according to the technique. The endovascular and surgical procedures have a complementary role.

[Pulmonary artery aneurysms in Behçet's disease: contribution of imaging in 5 cases]. / Anévrysmes des artères pulmonaires au cours de la maladie de Behçet.

Pulmonary involvement in Behçet's disease is an uncommon condition (12%). Thromboembolism of the superior vena cava and/or other mediastinal veins, aneurysms of the aorta and pulmonary arteries are the main vascular manifestations in addition to pulmonary infarct and intrathoracic hemorrhage. Despite their scarcity, respiratory symptoms may be life-threatening. The aim of this study was to assess the contribution of thoracic imaging for one of the most serious aspects of the disease: pulmonary artery aneurysm. We report five patients with pulmonary artery aneurysms (mean age: 39.5 years). Hemoptysia revealed Behçet's disease in three. Initially explored by conventional radiography, computed tomography and angiography, pulmonary artery aneurysms are currently investigated well with helicoidal computed tomography, digital angiography, magnetic resonance imaging (MRI) and angio-MRI. These imaging techniques provide helpful information for the diagnosis of Behçet's disease.
