Giant neurogenic tumors of mediastinum： report of two cases and literature review
摘要
Neurogenic tumors are commonly found in the mediastinum, especially in the posterior mediastinum or in the chest wall, neurogenic tumors may reach large size before becoming symptomatic. If the neurogenic tumor occupied more than half size of the chest wall accompanied by mediastinal shift, tracheal compression, or superior vena reflux disorder, it may be called giant intrathoracic neurogenic tumors. Giant intrathoracic neurogenic tumors are relatively rare. Most of intrathoracic neurogenic tumors were benign or low-grade malignant tumors in nature. Complete surgical excision should be the rule for these patients. We report two cases of giant neurogenic tumors, and study the clinical manifestations, diagnostic methods, surgical management, and prognosis in the light of the most important published data.
