Takayasu arteritis is a rare form of chronic inflammatory arteritis affecting large vessels, predominantly the aorta and its main branches. Those at highest risk are adolescent girls and women in their 2nd and 3rd decade of life, and this disease is most frequently seen in Japan, Southeast Asia, India, and Mexico. An elderly woman with Takayasu arteritis of late onset, an extremely unusual diso...

A 9-year-old Haitian girl presented initially with monocular blindness and an isolated temporal arteritis, confirmed by angiographic studies and temporal artery biopsy findings. CT and MR studies of the intracranial circulation showed only an enlarged, dense superficial temporal artery. Systemic workup revealed a mildly elevated erythrocyte sedimentation rate, mild changes in white and red bloo...

The role of autoimmunity in large-vessel vasculitis in humans remains unclear. We have previously shown that infection of gamma interferon receptor knockout (IFN-gamma R(-/-)) mice with gammaherpesvirus 68 (gamma HV68) results in severe inflammation of the large elastic arteries that is pathologically similar to the lesions observed in Takayasu's arteritis, the nongranulomatous variant of tempo...

We report the case of a giant cell arteritis (GCA) in an 81-year-old man who presented with headaches and a decreased general condition associated with an important inflammatory syndrome in laboratory analysis responding to corticotherapy. Color-duplex ultrasonography (CDU) features of temporal arteries obtained with a high frequency probe permits us to underline the typical radiological presen...
