Calcified Mediastinal Metastases from Ovarian Cancer Imaged With Tc-99m MDP SPECT

Abstract

A 41-year-old woman was hospitalized for dyspnea. Seventeen years earlier, she had had surgery for papillary ovarian cancer. Her chest CT revealed massive calcified mediastinal lymph node metastases and tracheal stenosis. Surgery confirmed the presence of calcified metastatic ovarian carcinoma of the mediastinal lymph nodes, and a tracheobronchial stent was inserted. Five months later, Tc-99m MDP bone scintigraphy showed no bone metastases, but there was remarkable radionuclide uptake in the right supraclavicular region and the mediastinum. SPECT images precisely visualized the radionuclide accumulation in the calcified lymph node metastases.
