急性化脓性甲状腺炎(acute suppurative thyroiditis,AST),是非特异性感染性疾病,其发病率低。由于甲状腺有完整的包膜保护、有非常丰富的血液供应及淋巴回流、局部碘离子的浓度高,因此甲状腺不易发生感染~([1-2])。AST在临床上罕见,且在早期症状往往不明显,仅表现为颈部疼痛,易被误诊为上呼吸道感染、亚急性甲状腺炎、结节性甲状腺肿等。本文就我院收治的曾被误诊误治的急性化脓性甲状腺炎3例的报道如下: Acute suppurative thyroiditis (AST) is a non-specific infectious disease with a low incidence.
