Arteriovenous fistulas of the thoracic wall may produce murmurs and thrills which suggest an intrathoracic vascular abnormality. Congenital arteriovenous fistulas in the plecordial region, the site of the fistula in the case here reported, may be confused with anomalies of the heart and great vessels. The differential diagnosis of blood vessel tumors of the chest wall is discussed. Occasionally...

malignant peripheral nerve sheath tumor (mpnst) is a rare nerve sheath tumor derived from schwann cells or pleuripotent cells of neural crest. neurogenic tumors make about 10-20% of all mediastinal tumors. incidence of mpnst is 0.001% in general population and 0.16% in patients with neurofibromatosis i (nf i). we report a case of 60 year female presenting with progressive cough and breathlessne...

INTRODUCTION Mediastinal dumbbell tumors are rare, and special cases provide valuable knowledge to the existing literature. PRESENTATION OF CASE A 57-year-old woman was diagnosed with a recurrent dumbbell-shaped nerve sheath tumor with intrathoracic and intraspinal components. We attempted to resect the tumor via combined biport thoracoscopy and laminectomy with the patient in a prone positio...

Extramedullary hematopoiesis is a rare cause of an intrathoracic mass in individuals with hemolytic disorders. It can be clinically confused with other tumors of the mediastinum. While radiologic studies often demonstrate findings suggesting intrathoracic extramedullary hematopoiesis, histology is usually required for diagnostic purposes. Thoracotomy was the mainstay procedure for obtaining tis...

BACKGROUND The aim of the study was to analyze the clinical and imaging characteristics of primary intrathoracic malignant peripheral nerve sheath tumors (MPNSTs). PATIENTS AND METHODS In this institutional review board (IRB)-approved retrospective study, clinical and imaging features of 15 patients (eight men; mean age 50 years [range 18-83)] with pathologically proven malignant peripheral n...

include neurogenic tumors and neoplastic lymphadenopathy. Cystic lesions including neurenteric cysts, lateral thoracic meningoceles, and mesothelial cysts rarely develop in the paraspinal region. Intrathoracic mesothelial cysts are fluid-filled and lined with mesothelial cells and are typically located in the anterior cardiophrenic angle (so called, pericardial cysts). However, they can occur i...
