The normal CT appearance of the superior diaphragmatic (also called cardiophrenic angle or pericardial) lymph node group was assessed in 39 adult patients who were free of diseases known to involve lymph nodes. In 15 patients there were 27 ovoid opacities, corresponding to known lymph node sites, namely in the anterior portion of the diaphragm; all except one opacity measured less than 5 mm in diameter. Superior diaphragmatic lymph nodes greater than or equal to 6 mm in diameter were observed in 30 of 190 patients with diseases known to be associated with lymphadenopathy. All but one of these patients had a pathologically proven malignant neoplasm, with bronchogenic carcinoma the most common etiology.
在39名无已知累及淋巴结疾病的成年患者中，评估了膈上（也称为心膈角或心包）淋巴结组的正常CT表现。15名患者中有27个椭圆形致密影，对应于已知的淋巴结部位，即在膈前部；除1个致密影外，所有致密影直径均小于5mm。在190名已知患有与淋巴结病相关疾病的患者中，有30名观察到直径大于或等于6mm的膈上淋巴结。除1名患者外，所有这些患者均经病理证实患有恶性肿瘤，其中支气管源性癌是最常见的病因。
