Incidentally diagnosed Takayasu arteritis on thyroid ultrasonography showing prominent collateral vessels of thyroidal arteries and common carotid artery occlusion

چکیده
We report a case of middle-aged woman incidentally diagnosed with Takayasu arteritis during the ultrasonography of a thyroid gland nodule. Prominent collaterals of the thyroidal arteries and a thin common carotid artery with mural thickening and deficient intraluminal flow signals were initially depicted on the ultrasonography with color Doppler. Subsequent magnetic resonance angiography and computed tomography aortography confirmed the diagnosis with the imaging features of a bilateral long segment common carotid artery occlusion and segmental stenosis of the left subclavian artery in addition to the suggestive physical findings.

Stenosis or Occlusion of the Right Subclavian and Common Carotid Arteries Is More Common than That of the Innominate Artery in Takayasu Arteritis
PURPOSE The aim of this study was to introduce the phenomenon that stenosis or occlusion occurs less frequently in the innominate artery than in the right subclavian and common carotid arteries, which are not first-order branches of the aorta, in Takayasu arteritis (TA). MATERIALS AND METHODS We retrospectively reviewed the medical records and image findings of all patients who were diagnosed...

BACKGROUND AND PURPOSE Despite prominent neurological symptoms reported in Takayasu arteritis (TA), a complete evaluation of the cerebral circulation has not been consistently performed. The purpose of this study is to describe MR angiography (MRA), color Doppler flow imaging, and transcranial Doppler (TCD) findings in the extracranial and intracranial cerebral arteries in TA. METHODS MRA, co...
متن کاملComplete ophthalmoplegia, complete ptosis and dilated pupil due to internal carotid artery dissection: as the first manifestation of Takayasu arteritis
BACKGROUND Takayasu arteritis is a rare, chronic large vessel vasculitis involving the aorta and its primary branches. As the disease progresses, the active inflammation of large vessels leads to dilation, narrowing and occlusion of the arteries. Arterial dissection is due to separation of the layers of the arterial wall resulting in a false lumen, where blood seeps into the vessel wall. Neurol...
متن کاملTakayasu arteritis in a young female
Background: Takayasu arteritis is a granulomatous vasculitis which mainly involves the large arterial vessels. The disease is rare and it is more common in females aged between 15-30 years old. In this paper, we report a case of takayasu arteritis in Babol, north of Iran. Case Presentation: A 22 - year old female was admitted to the Department of Infectious Diseases of Rouhani Teaching Hospital...
متن کاملSubclavian steal in Takayasu's arteritis. A hemodynamic study by means of ultrasonic Doppler flowmetry.
Blood flow in the vertebral artery and the upper extremity was studied in five cases of Takayasu's arteritis with subclavian steal by use of ultrasonic Doppler flowmetry and finger plethysmography. The diagnosis of subclavian steal was made by observation of flow reversal in the vertebral artery on the subclavian steal side during grip exercise and, in addition, the vertebral flow change with b...
