目的探讨肿块型胰腺炎的声像图特点,以提高对本病的认识及与胰腺癌的鉴别诊断能力。方法回顾性总结分析8例术前影像诊断为胰腺占位性病变而手术病理证实为肿块型胰腺炎的声像图表现、临床资料及CT影像结果。结果8例肿块型胰腺炎均表现为孤立性实性肿块。肿块位于胰头4例,钩突1例,胰体3例。肿块边界均模糊(8/8),但形态规则者占75%(6/8);肿块内部回声均呈低回声(8/8),其中回声不均匀者5例(5/8),均匀者3例(3/8);4例位于胰头及1例位于钩突部的肿块可见主胰管扩张(5/8),其中2例伴有胆总管扩张(2/8);7例肿块周边及内部未探及多普勒血流信号(7/8),仅1例肿块内探及血流(1/8)。8例肿块均未见浸润性生长(8/8)征象,7例未见周围或腹腔肿大淋巴结(7/8)。结论肿块型胰肠炎声像图有一定特点,超声检查仍可作为诊断肿块型胰腺炎的首选影像方法。
Objective To explore the sonographic features of mass pancreatitis in order to improve the understanding of the disease and its ability to differentiate pancreatic cancer. Methods The retrospective analysis of 8 cases of preoperative imaging diagnosis of pancreatic lesions and surgical pathology confirmed the mass pancreatitis pancreatitis, the clinical data and CT images results. Results 8 cases of mass pancreatitis showed solitary solid lumps. The tumor was located in the pancreas in 4 cases, 1 case of uncinate process, pancreatic body in 3 cases. The tumor boundaries were obscured (8/8), but the morphological regularities accounted for 75% (6/8). The internal echo of the tumor showed low echo (8/8), of which the echo was not uniform in 5 cases (5/8) In 3 cases (3/8); 4 cases located in the head of the pancreas and 1 case located in the uncinate process showed the main pancreatic duct dilatation (5/8), 2 cases with common bile duct dilatation (2/8); 7 cases No detection of peripheral and internal masses of the Doppler flow signal (7/8), only 1 case of exploration and blood flow (1/8). None of the 8 tumors showed signs of invasive growth (8/8), and 7 had no peripheral or peritoneal lymph nodes (7/8). Conclusions The sonographic features of mass pancreatitis have certain characteristics. Ultrasound can still be used as the imaging method of choice for the diagnosis of mass pancreatitis.
