Endovascular stent-grafting for recurrent aneurysm in Behcet's disease.

Arterial aneurysms represent a severe complication of Behcet's disease. A 42-year-old woman with Behcet's disease had a recurrence of an aneurysm after two surgical repair attempts using grafts. A covered stent-graft was implanted in her iliac external artery to occlude the neck of the aneurysm at the anastomosis of the bypass graft to her external iliac artery. The procedure reduced the size of the aneurysm by allowing the formation of a thrombus within its cavity. The implantation of an endovascular stent-graft may be a sound alternative to surgical repair for aneurysms associated with Behcet's disease.

MR findings with dynamic evaluation in Riedel's thyroiditis.

We reported the findings on MRI in a patient with proven Riedel's thyroiditis. The lesion was seen as slightly heterogeneous hypointensity on both T1- and T2-weighted images and had a mild enhancement after administration of gadpentate dimeglumine (Gd-DTPA). Dynamic MR study showed gradual increase in signal intensity of the lesion. These findings were different from those of thyroid neoplasms and were considered to reflect the mixture of inflammatory cells infiltration and fibrosis of Riedel's thyroiditis.
