We report the case of posterior mediastinal myxoid liposarcoma with right intra-pleural development operated through thoracotomy. observed a significant invasion segment descending aorta though there was no evidence tumor infiltration in preoperative imaging

The magnetic resonance (MR) findings are presented of a nonfunctioning mediastinal paraganglioma on both T1- and T2-weighted magnetic resonance images. The MR characteristics of this tumor differentiate it from previously reported functioning mediastinal paragangliomas (pheochromocytoma) and from other benign mediastinal neoplasms, although mediastinal bronchogenic carcinoma may produce a simil...

Teratomas are types of germ cell tumor which can arise from gonads or extragonadal tissues and show malignant transformation. . In this article,We presented a patient with enteric adenocarcinoma on the basis teratoma mediastinal mass invading sternum

INTRODUCTION Although spontaneous regression (SR) of anterior mediastinal seminoma is very rare with normalization of β-human chorionic gonadotropin (β-hCG) level, video-assisted thoracic surgery (VATS) is the most effective solution for definite diagnosis of indeterminate anterior mediastinal masses. DIAGNOSIS, THERAPEUTIC INTERVENTIONS, AND OUTCOMES A rare case of an asymptomatic 37-year-ol...
