[A case of Takayasu's arteritis with ulcerative colitis diagnosed by carotodynia and MRI findings].

We experienced a case of Takayasu's arteritis (TA) with ulceritive colitis (UC) having the onset of carotodynia, not accompanied by ischemic symptoms. MRI findings of the neck demonstrated a thickening of the bilateral carotid artery walls. The patient was treated by prednisolone with a marked improvement in both clinical symptoms and MRI findings. The patient had a unique HLA haplotype reported to correlate with both TA and UC. Carotodynia is an early but pathognomonic symptom of TA and MRI is helpful for the early diagnosis of TA.
