title: Unexpected findings on gallium-67 scintigraphy: detection of undifferentiated endometrial stromal sarcoma.
abstract: We reported an extremely rare case of undifferentiated endometrial stromal sarcoma imaged with gallium-67 scintigraphy. This previously healthy 32-year-old woman presented with cough and dyspnea for days. Unexpectedly, the pathology of the opacity in the right pulmonary hilar region demonstrated metastatic high-grade epithelioid sarcoma. Gallium scintigraphy performed to detect possible origin showed abnormal uptake in the right supraclavicular region, chest region and pelvic region. Computed tomography-guided biopsy of the pelvic mass revealed undifferentiated endometrial stromal sarcoma. This case demonstrated the usefulness of gallium-67 scintigraphy in the detection of the primary disease and the evaluation of the metastatic disease.
