Thirty-eight patients (16 males and 22 females) with mediastinal cysts have been treated at the Second Department of Surgery at Okayama University from 1978 to 1989. There were thirteen cases of thymic cyst, nine cases of pericardial cyst one case of pericardial diverticulum, eight cases of bronchogenic cyst, two cases of dermoid cyst, two cases of cystic lymphangioma, one case of esophageal cyst, one case of gastroenteric cyst, and one case of aneurysmal bone cyst. MRI seemed to be useful for the qualitative diagnosis of mediastinal tumors as cystic or solid. Based on Maier's classification and considering the result of this study, bronchogenic cysts may be divided into the following groups: 1) paratracheal, 2) carinal, 3) hilar, 4) paraesophageal [a) upper (Iu), b) lower (Im, Ei)], 5) cephalad recess of the azygos vein (CRAzV) and 6) miscellaneous. According to this new classification, these bronchogenic cysts could be allocated to (3) hilar: 1 cyst, (4-a) paraesophageal-upper: 1 cyst, (4-b) paraesophageal-lower: 1 cyst, (5) CRAzV: 4 cysts, and (6) miscellaneous: 2 cysts.
1978年至1989年期间，冈山大学第二外科共收治了38例纵隔囊肿患者（男性16例，女性22例）。其中胸腺囊肿13例，心包囊肿9例，心包憩室1例，支气管源性囊肿8例，皮样囊肿2例，囊性淋巴管瘤2例，食管囊肿1例，胃肠囊肿1例，动脉瘤样骨囊肿1例。MRI似乎有助于纵隔肿瘤囊性或实性的定性诊断。根据迈尔分类法并结合本研究结果，支气管源性囊肿可分为以下几组：1）气管旁型，2）隆突型，3）肺门型，4）食管旁型[a）上部（Iu），b）下部（Im，Ei）]，5）奇静脉头侧隐窝（CRAzV）型和6）其他型。根据这一新分类，这些支气管源性囊肿可分为：（3）肺门型：1例囊肿；（4-a）食管旁上部型：1例囊肿；（4-b）食管旁下部型：1例囊肿；（5）CRAzV型：4例囊肿；（6）其他型：2例囊肿。
