technetium-tc-99m-medronate and Renal-Insufficiency

Extrarenal uptake of Tc-99m DMSA is not seen very often. It has previously been described in metastatic disease and was mainly attributed to the presence of V-DMSA in the injected solution. We report a clinical case of incidental visualization of metastatic bone disease of the colon in a patient with renal failure. This could be the result of not only the presence of V-DMSA, but also the renal failure and the atypia of the lesions.

This case report describes the clinical, scintigraphic, and pathologic findings in a patient with an unexpected finding of a cutaneous malignant melanoma.. Multiple imaging studies were done, as was a pathologic examination of a suspicious pigmented lesion on the patient's back.. A Tc-99m MDP bone scan showed diffuse uptake in the skeleton, lungs, kidneys, and stomach.. Metastatic calcification, as shown by isotope scintigraphy, is an unusual manifestation of metastatic cancer from a primary cutaneous melanoma.

We describe a patient with unexplained hypercalcemia who under went bone scintigraphy, which demonstrated marked tracer uptake within the hilar lymph nodes. The pattern strongly suggested sarcoidosis, which was subsequently confirmed by bronchoscopy-directed biopsy.
