急性胰炎16名及慢性胰炎8名的CT影像的變化加以分析。急性胰炎的變化有胰臟器官性的腫大63%;胰臟周圍貯留液以左側前腎傍腔(Left pararenal space)佔75%,右側前腎傍腔(Right pararenal space)佔31%,小網膜腔75%;胰臟內貯留液佔31%,但有三例均有氣泡合併存在。胰臟內貯留液及氣泡同時存在時,可能為壞死性胰臟炎或胰膿瘍。慢性胰炎的CT影像變化的特點有局限性的器官性腫大佔12.5%,胰臟鈣化62.5%,主胰管擴張佔50%,假性囊腫佔37.5%,胰臟萎縮37.5%。慢性胰炎有時與臟癌的CT影像相似,須慎重區別。胰臟電腦斷層攝影對胰炎較其他的檢查(胰臟形態學)更為具體與準確。
We had collected C.T. of acute pancreatitis in 16 cases and chronic pancreatitis in 8 cases for analysis since September 1980 to December 1982. The C.T. pictures of the acute pancreatitis were enlargement of pancreas in 63%, pancreatic fluid collection 31% and extrapancreatic phlegmon & gas bulb in the pancreas. The most common location of the phlegmon collection was in the lesser sac and in the left anterior pararenal space (75% in each side). The gas bulb and the pancreatic fluid collection were the important signs of necrotizing pancreatitis which was proved by the surgery in four cases. Generally, the C.T. picture of acute pancreatitis was useful and significant in the diagnosis. The diagnostic criteria of chronic pancreatitis were enlargement of pancreas (12.5%) (focal), calcification (62.5%), dilatation of main pancreatic duct (50.0%) and parenchymal atrophy (12.5%). Usually, one or more hallmarks of chronic pancreatitis were present. The differential diagnosis between chronic pancreatitis and pancreatic cancer was not easy by the C. T. picture.
