A comparative study of the atypical CT findings and pathological features of bladder leiomyoma / 中华泌尿外科杂志

ABSTRACT

Objective To investigate the relationship between the atypical CT findings and pathological features of bladder leiomyoma.Methods A retrospective analysis of the CT findings and pathological features was conducted in 9 cases of atypical bladder leiomyoma.All the 9 cases were females aged 27 to 53 years (average 38 years).All patients had plain and enhanced spiral CT scans and were treated surgically.Results The atypical CT findings of bladder leiomyomas showed as similar malignant tumor signs (n =3),solid mass with obvious inhomogeneous enhancement (n =5) and solid mass with no enhancement (n =1).All cases had lesions appearing as solid lobulated cystic mass in different degrees,whose solid part showed intermediate density on CT,with heterogeneous enhancement after contrast agent injection.Tumor cell and interstitial cell swelling to varying degrees,vascular hyalinosis,myxoedema,hyalinosis and cystic degeneration were found in these lesions.CT findings showed the consistency with similar malignant tumor signs and pathological showed bigger tumor volume,obvious interstitial edema,red degeneration,cystic degeneration and significantly increasing enlargement circuitous blood vessels.While the CT findings of the obvious inhomogeneous enhancement solid mass and pathological showed moderate tumor size,relatively obvious interstitial edema and cystic degeneration,significantly increasing enlargement circuitous blood vessels were consistent.The consistency was found among mild enhancement solid tumors and pathological showed mild interstitial edema,mild degeneration and no enlargement circuitous blood vessels.Conclusion Through the contrast analysis,atypical CT performance and pathological features might have some certain correlation.
