Noninvasive Detection of Active Microcalcification in an Occlusive Peripheral Vascular Aneurysm Using (18)F-NaF PET/CT Imaging

A 65-year-old man with an occluded popliteal artery aneurysm and calf claudication underwent PET/CT imaging with (18)F-NaF to assess the status of active microcalcification in the aneurysm site and additional lower extremity arteries. CT imaging revealed macrocalcification of the aneurysm that coloc...

Sumario:A 65-year-old man with an occluded popliteal artery aneurysm and calf claudication underwent PET/CT imaging with (18)F-NaF to assess the status of active microcalcification in the aneurysm site and additional lower extremity arteries. CT imaging revealed macrocalcification of the aneurysm that colocalized with elevated retention of (18)F-NaF on PET images. PET/CT detected additional distal arterial sites with focal uptake of (18)F-NaF that did not coincide with CT-detectable macrocalcification. This report highlights a case of active microcalcification in an occlusive peripheral aneurysm using PET/CT. PET/CT may provide molecular insight into the remodeling of lower extremity aneurysms and atherosclerotic lesions.
