8 下列何者與甲狀腺癌的診斷，最無關係？

血清甲狀球蛋白（Thyrogobulin） 血清抑鈣激素（Calcitonin）

RET基因分析頸部超音波

ans A

Thyroglobulin levels in the blood can be used as a tumor marker^[2] for certain kinds of thyroid cancer. Thyroglobulin levels in the blood can also be elevated in cases of Graves' disease.

9 5歲男孩，並無發燒或高血壓病史，突然發生右側肢體無力，經腦部電腦斷層檢查，發現左側前腦動脈供應區呈現缺血性梗塞，核磁共振動脈攝影（MRA）及腦血管攝影顯示兩側前腦動脈及中腦動脈供應區出現不正常毛玻璃樣血管叢。下列四項診斷中，那一項最符合？

左側前腦動脈瘤破裂，併發血管收縮基底核區之動靜脈畸形

毛毛樣腦血管症（Moyamoya Disease） 腦動脈炎併發血管阻塞

Moyamoya syndrome is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by the constriction, and also by blood clots (thrombosis).^[1]

The blood vessels develop collateral circulation around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to hemorrhage, aneurysm and thrombosis. On X-rays, these collateral vessels have the appearance of a "puff of smoke" ("moyamoya" in Japanese).^[1]

The disease causes constrictions primarily in the internal carotid artery, which travels from the neck up inside the skull just under the brain in the cavernous sinus. At the Circle of Willis, the internal carotid artery flows into the middle cerebral artery, which continues into the brain, and the anterior cerebral artery, which is part of the Circle of Willis. Moyamoya disease often extends to the middle and anterior cerebral arteries

10 承上題，以下之敘述，何者最可能是該小孩之腦血管攝影所發現到的結果？

右側內頸動脈在進入顱底處，呈現擴張及血流加快

左側內頸動脈在進入顱底處，呈現狹小或阻塞

基底動脈（basilar artery）在腦內之分叉處，呈現狹小或阻塞

兩側基底核區（basal ganglia），側枝循環血管不明顯，顯著的血流減少
