Fine-needle aspiration cytology (FNAC) is considered a safe procedure, but it causes massive neck swelling and airway obstruction rarely. Neck swelling after FNAC is caused by two mechanisms: by hematoma or by release of vasodilator substances in thyroid cells and nerve terminals. The latter condition was previously reported as an acute and frightening swelling of the thyroid, but is not named appropriately. For convenience, we therefore refer to the condition as dTSaFNA (diffuse thyroid swelling after fine-needle aspiration) in this report. dTSaFNA is usually transient and rarely results in airway obstruction. We report one case of thyroid hematoma and two cases of dTSaFNA. All three cases were treated in hospital and recovered completely.
细针穿刺细胞学检查（FNAC）被认为是一种安全的操作，但它很少引起颈部大量肿胀和气道阻塞。FNAC后颈部肿胀由两种机制引起：血肿或甲状腺细胞及神经末梢中血管扩张物质的释放。后一种情况以前被报道为甲状腺急性且可怕的肿胀，但命名并不恰当。因此，为方便起见，在本报告中我们将这种情况称为细针穿刺后弥漫性甲状腺肿胀（dTSaFNA）。dTSaFNA通常是短暂的，很少导致气道阻塞。我们报告1例甲状腺血肿和2例dTSaFNA病例。所有3例均在医院接受治疗并完全康复。
