| Abstract
Medullary thyroid carcinoma accounts for 4% of thyroid carcinoma and originates from parafollicular cells, secreting
calcitonin and carcinoembryonic antigen (CEA). Conventional radiographic modalities such as Computerized Tomography
(CT), Magnetic Resonance Imaging (MRI), and Ultrasonography (U/S), are used for detecting recurrences following
total thyroidectomy. However, metastatic disease frequently escapes detection by the above modalities, even
when its presence is suggested by persistently elevated serum calcitonin levels. In this paper, we report a case of medullary
thyroid carcinoma in a 40 year-old woman who had whole body octreotide scintigraphy to evaluate and detect the
origin of calcitonin and CEA secretion.
