Tc-99m dicarboxypropane diphosphonate uptake in ovarian fibrothecoma.
A 76-year-old woman had a palpable mass in the lower abdomen. Computed tomography showed an abnormal pelvic mass with necrotic areas, probably of ovarian origin. A Tc-99m dicarboxypropane diphosphonate whole-body scan performed to evaluate the extent of the disease (i.e., the presence of bone metastases) revealed only diffuse uptake of the tracer in the pelvis. Histopathologic analysis after surgical excision of the mass revealed a fibrothecoma of the right ovary, which is a benign tumor composed of cells derived from the ovarian stroma and, in some instances, resembles the thecal element of the follicle.
