Nasal-Tip Metastasis on 18F-FDG PET/CT Scan in a Patient With Squamous Lung Carcinoma
A 64-year-old man found a painless soft tissue mass on his nasal tip 3 months ago. The biopsy pathology indicated a metastatic squamous carcinoma. An 18F-FDG PET/CT scan was performed to detect the primary malignancy, and it demonstrated multiple 18F-FDG–avid lesions involving the nasal tip, bilateral lungs, right hilum and mediastinum, and rectum. The nasal-tip mass with high radioactivity was diagnosed as the metastasis from squamous lung carcinoma, which was confirmed by the biopsy of a lung lesion.
