支气管囊肿(BC)是一种先天性异常,最常见于纵隔和肺,很少在隔膜中。我们报告了2例起源于左diaphragm肌的支气管囊肿。病例1涉及一名50岁的男性,他因高血压接受了肾上腺计算机断层扫描(CT),显示左肾上腺改变。我院肾上腺CT显示左膈上方有占位病变。我们在第七肋间间隙进行了左侧开胸手术,发现肿块完全位于隔膜中。病例2是一名58岁的女性,在标准健康检查下接受了胸部CT检查,在左下肺叶后基底段发现约4cm的胸膜下病变。在胸腔镜手术中,发现质量来自隔膜的表面,与肺组织无关。2例经手术病理证实为膈型支气管囊肿。由隔膜引起的异位支气管囊肿非常罕见,膈支气管囊肿通常发生在左侧,在女性中,在脊柱和隔膜之间的角度。据我们所知,没有与病例1类似的膈肌内BCs的相关报道,病例1完全位于膈肌内.大多数膈肌BCs位于膈肌表面,并向胸腔或腹腔突出。此外,双目膈支气管囊肿,与案例2类似,尚未报告。
The bronchogenic cyst (BC) is a type of congenital anomaly that is most usually found in the mediastinum and lung, and rarely in the diaphragm. We report two cases of bronchogenic cysts originating from the left diaphragm.
Case 1 involved a 50-year-old man who underwent computed tomography (CT) of the adrenal glands for hypertension, showing left adrenal changes. An adrenal CT at our hospital showed a space-occupying lesion above the left diaphragm. We performed a left-sided thoracotomy in the seventh intercostal space and found that the mass was entirely located in the diaphragm.
Case 2 was a 58-year-old woman who underwent chest CT under a standard health check-up, and a subpleural lesion of approximately 4 cm was found in the posterior basal segment of the left inferior lung lobe. During thoracoscopic surgery, the mass was found to originate from the surface of the diaphragm, having no correlation with the lung tissue. The two cases of diaphragmatic bronchogenic cysts were confirmed by surgical pathology. Ectopic bronchogenic cysts arising from the diaphragm are very uncommon, and diaphragmatic bronchogenic cysts typically occur on the left side, in women, and in the angle between the vertebral column and the diaphragm. As far as we know, there are no relevant
reports of intradiaphragmatic BCs similar to
case 1, which was entirely located within the diaphragm. Most diaphragmatic BCs are located on the surface of the diaphragm and project toward the thoracic or abdominal cavities. Moreover, bilocular diaphragmatic bronchogenic cysts, similar to
case 2, have not yet been reported.
