Abstract

Objective To discuss findings of urachal carcinoma by spiral CT, and discuss the value of spiral CT in the diagnosis of urachal carcinoma. Methods The CT findings and MPR features of nine cases with diagnosed by pathological examination in our hospital were included in this study. Surgically proven urachal carcinomas were retrospectively reviewed, and theCT images were evaluated to determine tumor localization, boundary, morphology, growth trend, density, enhanced pattern, and metastases were analyzed. Results CT in all nine cases showed a mass located in the midline or slightly off center line between the dome of the bladder and the umbilicus. nine cases were mixed cystic solid lesions. Calcifications were present in six cases. Urachal carcinoma grow along with the urachus，about half of them invasion of right anterior superior wall of bladder and grow right up front. The tumor can form a distant metastasis on the bladder wall. Conclusion spiral CT examinations and MPR reconstruction before surgery has important reference value to correctly diagnose of urachal carcinoma which showed unique location and characteristic imaging findings.
