Abstract
|
|
|
|
A 65 year-old man with hepatocellulcar carcinoma (HCC) admitted to treat left lower leg swelling and pus discharge suspecting osteomyelitis. MRI of his lower leg revealed the bone metastasis. Whole body FDG PET/CT additionally detected left shoulder and right ilium metastasis. Hematemesis suddenly developed in this patient after 3 weeks. Metastasis of right tonsil was histologically proven. When we reviewed his FDG PET/CT, there was asymmetric mild hypermetabolism in the right tonsil. When focal hypermetabolism is shown in the organ physiologically taking glucose up such as tonsil, we should cautiously assess whole body PET/CT in the examination of distant metastasis. We present a patient with multiple distant metastasis including tonsil from HCC showing increased FDG uptake with the literature review.
