Solitary hepatic metastasis from medullary thyroid carcinoma mimicking atypical hemangioma: insights from multimodality diagnostic approach by MRI, F-18 FDG and F-18 FDOPA PET/CT.

摘要

Medullary thyroid carcinoma (MTC) is an uncommon malignant endocrine tumor. Distant metastases occur frequently in patients with elevated serum calcitonin values. Surgery remains the mainstay of treatment, so the early detection of metastatic involvement is crucial for patient outcome. F-18 FDOPA PET/CT seems to be a promising diagnostic tool for disease recurrence detection. We report the results of multimodality diagnostic approach by MRI, F-18 FDG, and F-18 FDOPA PET/CT in a patient with a solitary hepatic metastasis from MTC mimicking atypical hemangioma.
