Case in brief

A 43-year-old man presented with progressive facial and neck swelling, leading to a diagnosis of superior vena cava syndrome. Imaging revealed an irregular low-density mass in the superior vena cava with significant tracer uptake on PET/CT. Tumor markers showed a mild elevation of NSE. The patient underwent resection and SVC replacement, with the final diagnosis of classic seminoma.

Diagnostic / clinical pearl

Clinicians should consider primary tumors like seminoma in cases of superior vena cava syndrome, especially when imaging reveals suspicious masses.
