title: Increased 99mTc-MDP Activity in a Partially Calcified Malignant Mediastinal Teratoma.
abstract: A 41-year-old woman presented with cough and shortness of breath for 3 weeks. Chest x-ray and CT showed a large, partially calcified soft tissue mass adjacent to the right side of the heart. Whole-body bone was acquired to evaluate possible metastases, which showed abnormal accumulation of Tc-MDP in the right chest. Further SPECT/CT imaging that demonstrated intense Tc-MDP activity was mainly in the calcification portion of mass. Histopathological examination from biopsy specimen of the lesion was consistent with malignant teratoma.
