Abstract

Objective: To investigate the value of MRI combined with DWI in diagnosing colorectal mucinous adenocarcinoma combined with abscess. Methods: The clinical, MRI and DWI data of 14 patients with colorectal mucinous adenocarcinoma combined with abscess confirmed by pathology were retrospectively analyzed. The ADC values were calculated and compared in the region of interest of tumor and abscess. Results: Among the 14 patients with colorectal mucinous adenocarcinoma combined with abscess, the lesions located at the rectum in 6 patients, at the ascending colon in 4 patients, at the descending colon in 2 patients, at the transverse colon in 1 patient, at sigmoid colon 1 patient. The tumors combined with abdominal abscess in 4 patients, pelvic abscess in 3 patients, uterus abscess in 2 patients, abdominal wall abscess in 2 patients, prostate abscess in 1 patient, perianal abscess in 1 patients, splenic abscess in 1 patient. The tumors appeared as irregular massive type, the length was 4.7~16.4cm; The abscess appeared as round, oval and irregular, the length was 1.8~7.3cm. The tumors showed as low or slightly low signal on T1WI, heterogeneously high signal on T2WI, heterogeneously high signal or slightly high signal on DWI, and high signal on ADC; The abscess appeared as low signal on T1WI, high signal on T2WI, obviously high signal on DWI, and obviously low signal on ADC. The DWI signal of colorectal mucinous adenocarcinoma was lower than that of abscess, and the ADC signal was higher than that of abscess. The average ADC value of colorectal mucinous adenocarcinoma was 1.89 ± 0.23×10-3mm2/s, and the average ADC value of abscess was 0.72 ± 0.13×10-2mm2/s, and the difference was statistically significant (t=18.330, P<0.001). Conclusion: MRI combined with DWI, ADC and ADC value played an important role in the diagnosis of colorectal mucinous adenocarcinoma combined with abscess.
