The purpose of our study was to describe the CT findings of acute cholecystitis and apply previously proposed CT criteria for its diagnosis.
We retrospectively reviewed CT scans of 29 patients with proven acute cholecystitis. Scans were reviewed for gallstones, gallbladder distension, bile density, wall thickening, pericholecystic fluid, subserosal edema, pericholecystic stranding, and sloughed membranes. Previously published criteria were applied to determine the percentage of patients that met positive criteria for acute cholecystitis.
The most common CT findings, in decreasing order of frequency, were wall thickening (n = 17), pericholecystic stranding (n = 15), distension (n = 12), pericholecystic fluid (n = 9), subserosal edema (n = 9), high-attenuation bile (n = 7), and sloughed membranes (n = 1). Of the 29 cases of acute cholecystitis, 15 met previously published CT criteria.
CT can be useful in diagnosing acute cholecystitis. Common CT findings of acute cholecystitis include wall thickening, pericholecystic stranding, distention, high-attenuation bile, pericholecystic fluid, and subserosal edema. When these findings are present, the diagnosis of acute cholecystitis can be suggested. However, previously published CT criteria failed to identify a significant number of patients with acute cholecystitis.
我们研究的目的是描述急性胆囊炎的CT表现，并应用先前提出的CT诊断标准。
我们回顾性分析了29例经证实的急性胆囊炎患者的CT扫描图像。对扫描图像进行评估，观察有无胆结石、胆囊扩张、胆汁密度、胆囊壁增厚、胆囊周围积液、浆膜下水肿、胆囊周围条索状影及脱落的黏膜。应用先前发表的标准来确定符合急性胆囊炎阳性标准的患者比例。
最常见的CT表现，按出现频率递减依次为胆囊壁增厚（n = 17）、胆囊周围条索状影（n = 15）、胆囊扩张（n = 12）、胆囊周围积液（n = 9）、浆膜下水肿（n = 9）、高密度胆汁（n = 7）及脱落的黏膜（n = 1）。在29例急性胆囊炎病例中，15例符合先前发表的CT标准。
CT对急性胆囊炎的诊断有帮助。急性胆囊炎常见的CT表现包括胆囊壁增厚、胆囊周围条索状影、胆囊扩张、高密度胆汁、胆囊周围积液及浆膜下水肿。当出现这些表现时，可提示急性胆囊炎的诊断。然而，先前发表的CT标准未能识别出相当数量的急性胆囊炎患者。
