Diagnostic and therapeutic approaches for masses in the posterior mediastinum.
Between January 1980 and December 1997 twenty-one patients with a mass in the posterior mediastinum came under our observation. All of the patients underwent chest radiography, bronchoscopy, respiratory function tests, perfusional and ventilatory radionuclide scans, a computed tomography (CT) of the chest and blood gas analysis. In cases involving neurogenic tumours magnetic resonance imaging (MRI) was used. Ten patients underwent CT guided transthoracic needle biopsy. The excision was performed by means of a thoracotomy in 12 cases (57.1%) and by video assisted thoracoscopy surgery (VATS) in the other 9 (42.9%); no deaths were recorded. Eleven neurilemmomas, two bronchogenic cysts, two paragangliomas, two neuroepitheliomas, one neurogenic sarcoma and three esophageal duplications were found. The authors believe an accurate pre-operative assessment of the lesion can be obtained using CT and MRI. The video assisted thoracoscopy (VAT) is a useful method of diagnosis and treatment as it can be converted into VATS if the lesion is benign or cystic. Thoracotomy is necessary when the mass is malignant or when there is adhesion to or invasion of surrounding tissues.
