PET/CT scans ‘crucial’ in patients with NK/T-cell lymphoma
By Will Morton
PET/CT has significant advantages over conventional methods for lesion detection and staging in patients with natural killer/T-cell lymphoma.
December 22, 2023
A 50-year-old man with recently diagnosed nasal-type NK/T-cell lymphoma underwent an F-18 FDG-PET/CT scan (A–D) for initial staging. Maximum-intensity-projection image (A) shows hypermetabolic lesions in both ethmoid sinus (thin arrow), both cervical lymphatic chains (arrowhead), left upper lung (thick arrow), liver, and spleen. Transaxial images show an F-18 FDG-avid mass in both ethmoid sinus (B). The scan shows intense F-18 FDG radiotracer uptake in left upper lung and uptake in the liver and spleen (CT showed no lesions), suggesting malignancy (C–D). Finally, after the PET/CT scan was done, the patient’s staging was changed from II to IV.

Patient underwent a lumpectomy with tumor-negative surgical margins and radiation therapy. (B) Mammographic magnification view obtained four years after diagnosis shows new calcifications at the surgical site (circle). Stereotactic biopsy was performed, which revealed recurrent grade 2 DCIS. The patient then underwent a mastectomy. Image courtesy of the ARRS.
