Abstract
Objective To compare the initial detection rate and the accuracy of qualitative diagnosis of multislice spiral computed tomography (MSCT),gastrointestinal tract radiography,gastroscopy,and endoscopic ultrasonography in the diagnosis of gastric lipoma,with a focus on evaluating the diagnostic value of MSCT.Methods Twenty-six patients with gastric lipoma,6 males and 20 females with a mean age of 61 years (ranging from 41 to 82 years) and confirmed by pathology,were enrolled in the present study.Their clinical,pathologic and imaging findings were retrospectively analyzed.All the patients underwent gastroscopy,and plain and dynamic enhanced MDCT scans.Of them 21 cases underwent endoscopic ultrasonography and 12 cases gastrointestinal tract radiography.Results The detection rate was 88.5％(23/26) and 80.8％(21/26),P＞0.05 for MSCT and gastroscopy,respectively,in the initial diagnosis of gastric lipomas,both higher than that of gastrointestinal tract radiography (41.7％,5/12).The accuracy of qualitative diagnosis of MSCT (100％,23/23) was higher than that of endoscopic ultrasonography (71.4％,15/21),gastrointestinal tract radiography (0％,0/5) and gastroscopy (0％,0/21).The lesions located at the gastric antrum in 18 cases (69.2％,including 10 front wall,6 posterior wall and 2 pyloric canal),the gastric body in 7 cases (26.9％) and the gastric fundus in 1 case (3.8％).All the lipomas presented as round or ovoid nodule with clear boundary on MSCT images,and homogeneous or mixed low density.The CT values,long dimensions and volumes ranged from-50 to-95Hu (mean-72.58Hu),5.7 to 40.7mm (mean 17.67mm) and 0.02 to 7.03cm3 (mean 1.89cm3),respectively.Contrast-enhanced CT scans showed no enhancement in all the lesions.Conclusion MSCT can make accurate locating and qualitative diagnosis for gastric lipomas.关键词
