title: Reversible findings of methylene diphosphonate bone scintigraphy in Raynaud's phenomenon: case report and review of the literature.
abstract: A 53-year-old woman with carcinoma of the right breast, spinal metastases and right arm lymphoedema was referred for bone scintigraphy prior to commencement of chemotherapy. The patient arrived in the department complaining of pain in the left hand, which appeared red and slightly swollen. Bone scintigraphy revealed increased tracer uptake in the first four metacarpal and all the carpal bones of the left hand. A repeat three-phase bone scintigram, performed 1 week later when the patient was asymptomatic, showed equal blood flow to both hands with normal blood pool and uptake in bone images. The case demonstrates a state of reversibly increased bone uptake in a patient injected at the time of an episode of Raynaud's phenomenon and the possible implications for scan interpretation.
