The computed tomographic (CT) findings in seven cases of mediastinal bronchogenic cysts were reviewed. Two showed homogeneous high density masses with CT numbers of 97 and 89 Hounsfield units (HU). One had a CT number of 40 HU. Four cases had low density masses with CT numbers ranging from -3 to 20 HU; however, two of these four low density masses had either high density outer walls or deposits. All but one of the patients' chest radiographs revealed similar water density masses. Radiographic evidence of calcium deposits was previously considered rare, but its demonstration with CT appears to be common in mediastinal bronchogenic cysts.
回顾了7例纵隔支气管源性囊肿的计算机断层扫描（CT）表现。2例显示均匀高密度肿块，CT值分别为97和89亨氏单位（HU）。1例CT值为40 HU。4例为低密度肿块，CT值范围为-3至20 HU；然而，这4个低密度肿块中有2个有高密度外壁或沉积物。除1例患者外，所有患者的胸部X线片均显示类似的水样密度肿块。钙化沉积的影像学证据以前被认为很少见，但CT显示在纵隔支气管源性囊肿中似乎很常见。
