title: Role of CT-guided core needle biopsy in the diagnosis of a gossypiboma: case report.
abstract: A 66-year-old woman with previous hysterectomy had dysuria and vaginal spotting for 1 month. Computed tomography showed a heterogeneous presacral mass with eccentric calcification. Biopsies of the bladder and vagina and transrectal biopsy of the pelvic mass yielded only inflammation. T2-weighted magnetic resonance images revealed a heterogeneous mass with wavy hypointensities. Computed tomographically guided biopsy targeting at the calcified area disclosed thread-like materials, thus confirming the diagnosis of gossypiboma.
