Abstract

A 65-year-old man with left orbital mass and recent vision loss underwent FDG PET/CT, which showed intensely FDG-avid anterior left orbital mass invading the periorbital soft tissue. Enlarged left retromandibular, mediastinal, and abdominal lymph nodes with intense FDG uptake were suspicious for malignancy. Left orbital exenteration revealed moderately differentiated squamous cell carcinoma. Fine needle aspiration of mediastinal lymph nodes revealed inflammatory processes; therefore, the left retromandibular lymph node was felt to be benign and no biopsy was performed. However, follow-up PET/CT demonstrated significant increase in size and uptake of the left retromandibular lymph node, which was proven metastatic in subsequent biopsy.
