Multiple annular lung metastases from a nasopharyngeal
Submitted Oct 22, 2012. Accepted for publication Nov 29, 2012.
A 41-year-old man was diagnosed with “nasopharyngeal
carcinoma with multiple lung metastases”. Histological
diagnosis was a poorly differentiated, non-keratinizing
squamous cell carcinoma. Incidentally, chest CT revealed
multiple metastases presented as annular lesions. The
annular walls were smooth (Figures 1,2). This case
represents a rare pattern of neoplasm metastasis.

scan 8 months later exhibits size of annular metastases (arrowheads)
has enlarged and their number has increased, accompanied by
