Abstract: | A sixty year old female referred for thyroid and liver scintigraphy had a clinical history of progressive swelling in the neck with hepatomegaly. A large cold area was detected in the right thyroid lobe using 99mTc pertechnetate and in the right lobe of liver using 99mTc phytate. Subsequent whole body scan with 99mTC DMSA(V) showed avid tracer uptake in right lobe of thyroid and liver. Aspiration cytology of thyroid and liver showed medullary carcinoma of thyroid with its metastasis in liver. Histopathology following thyroidectomy confirmed the diagnosis. Thus 99mTc pentavalent DMSA contributes specificity to diagnose medullary carcinoma of thyroid and metastatic lesions. |
