swelling on left side of neck. Longitudinal sonogram shows fusiform swelling
of arterial wall (arrows).
Fig. 1C.65-year-old woman with pancreatic carcinoma and painful
swelling on left side of neck. MDCT scan before chemotherapy shows
contrast-enhanced supraaortal vessels (arrows) with normal vessel
wall caliber.
Fig. 1D.65-year-old woman with pancreatic carcinoma and painful
swelling on left side of neck. MDCT during chemotherapy shows wall thickening
in supraaortal vessels with increased contrast enhancement of vessel walls
(arrows), suggesting vasculitis.

swelling on left side of neck. MDCT after chemotherapy shows almost complete
resolution of the arterial wall thickening (arrows).
