Detection of medullary thyroid cancer with MIBG imaging for pheochromocytoma
Adrenal Gland Neoplasms
A medullary thyroid cancer (MTC)/multiple endocrine neoplasia syndrome was suspected in a patient having an metaiodobenzylguanidine (MIBG) scan while she was being investigated for pheochromocytoma. After surgery, this was confirmed histologically. Although MIBG scanning cannot be used as a screening tool for MTC because of its poor sensitivity for detection of MTC, this case report highlights that one should always scrutinize the thyroid gland while interpreting MIBG scans.
