纵隔七分区法对异位胸腺瘤的影像学诊断价值

目的　探讨采用 7分区法对异位胸腺瘤的影像学诊断价值。方法　 11例经活检和手术病理证实的异位胸腺瘤患者 ,从胸片、CT、MRI的影像学表现与手术结果进行分析研究。结果　 11例异位胸腺瘤纵隔 9分区法分别位于左侧中中、中下纵隔 3例 ,右侧中中、中下纵隔 4例 ,右侧前中、前下纵隔 4例。 11例在纵隔 7分区法均在前下纵隔。结论　纵隔 7分区法对胸腺瘤的定性诊断的正确性具有明显的价值 ,对于明确手术切除方法具有重要意义。

Imaging Diagnostic Value Using Seven Division for Dystopic Thymomas in Mediastinum

Objective To discuss the imaging diagnostic value using seven division for dystopic thymomas in mediastinum. Methods 11 cases of dystopic thymomas proved by biopsy and histopathology were analyzed based on chest radiography, computed tomography (CT) and magnetic resonance imaging (MRI) .Results According to nine division, 3 cases located in left mid-middle and mid-inferior mediastinum, 4 cases in right mid-middle and mid-inferior mediastinum, 4 cases in right ante-middle and ante-inferior mediastinum.While according to seven division,all cases (11) located in ante-inferior mediastinum. Conclusion Seven division of mediastinum is of great value in diagnosing dystopic thymomas and in guiding clinical management.
