RESUMO
A young patient with severe generalized osteopenia and multiple compressed vertebral fractures caused by systemic mastocytosis is presented. Extensive clinical, laboratory, and pathologic examination showed the involvement of the skeleton alone. Follow-up bone scintigraphy with Tc-99m MDP during a period of 6 years demonstrated migratory multiple axial lesions. These results suggest that Tc-99m MDP imaging is an accurate detection of the activity of the disease.

Colon carcinoma, cholangiocarcinoma, malignant melanoma and liver metastases detected on bone imaging have been reported with different bone seeking radiopharmaceuticals. This report is concerned with an interesting case of oat cell carcinoma with hepatic metatases visualized on 99mTc-diphosphonate bone imaging. This has not been previously reported.

67Ga-citrate scan from skull to mid-abdomen showed increased uptake in both parotid glands, mediastinum, lungs, uvei and/or enlarged lacrimal glands. The differential diagnosis of the positive radiogallium scan is discussed with emphasis on the value of the extrathoracic findings. Tissue diagnosis confirmed the imaging diagnosis of sarcoidosis. The case illustrates the usefulness of double radionuclide study--67Ga and 99mTc-MAA--and of the tomographic scanner in defining the spread of the active granulomatous disease.
