Hepatodiaphragmatic interposition of the intestine (HDI) is a common radiological finding in the normal population of Iran compared to Western countries (0.22% vs 0.02%). A high incidence of this finding was observed in patients with chronic lung disease (2.7%) and in women near term pregnancy (2.0%). A striking incidence of 22% was observed in patients with post-necrotic cirrhosis. Probable contributing factors are: (a) a redundant bowel with increased mobility, (b) an enlarged lower thoracic outlet in conditions such as pregnancy, emphysema, and cirrhosis with ascites, (c) an atrophic liver of post-necrotic cirrhosis, which leaves adequate space for intrusion of adjacent bowel segments. HDI of the bowel is generally an asymptomatic condition and its finding on a chest radiograph suggests atrophic cirrhosis of the liver.
与西方国家相比，肠肝膈间位（HDI）在伊朗正常人群中是一种常见的放射学表现（0.22%对0.02%）。在慢性肺病患者（2.7%）和妊娠晚期女性（2.0%）中观察到该表现的高发生率。在坏死性肝硬化患者中观察到惊人的22%的发生率。可能的促成因素有：（a）肠管冗长且活动度增加；（b）在妊娠、肺气肿和肝硬化伴腹水等情况下胸廓下口扩大；（c）坏死性肝硬化导致肝脏萎缩，为相邻肠段的侵入留出足够空间。肠肝膈间位通常是一种无症状的情况，其在胸部X线片上的发现提示肝脏萎缩性肝硬化。
