Objective To evaluate the value of CT in diagnosis of adnexal abscess retrospectively.Methods The characteristic CT findings in 26 patients with adnexal abscess proved by histopathology were reviewed retrospectively.Results Of 26 patients,the adnexal abscess was presented in unilateral lesions(n=6) and bilateral lesions(n=20).There were total 46 lesions,which were pyosalpingitis (n=33) and tubo-ovarian abscess (n=13),respectively.CT findings of pyosalpingitis included dilated, thick-walled, enhancing fallopian tubes containing complex fluid.CT findings in tubo-ovarian abscess were thick-walled and multiloculated cystic masses,which had thick mural enhancement with multilayered appearance (n=10).Reactive inflammation of adjacent structures(n=21) manifested as haziness and stranding of the pelvic fat,thickening of the uterosacral ligaments, and pelvic peritonitis.Small or large bowel ileus (n=5) and hydroureter (n=3) resulted from adjacent inflammation of tubo-ovarian abscess.Endometritis was seen in 19 patients and ascites in 18 patients.Conclusion Familiarity with the CT appearances is important for timely diagnosis and treatment of adnexal abscess and its complications.
