患儿因“左眼红肿12 d”就诊。左上睑红肿(++++),眼眶鼻侧可触及约黄豆大小硬结,界不清,质地中等,压痛(?),伴上睑下垂,遮盖角膜下缘。双眼眼位正,左眼眼球外转轻度受限。眼眶及视神经MRI显示左眼上睑软组织肿胀,考虑炎性改变。入院诊断为左眼特发性眼眶炎性假瘤(Idiopathic orbital inflammatory pseudotumor,IOIP)。予以激素治疗后症状好转且随访期间无复发。本例患儿为拒绝外院活检而就诊于暨南大学附属第一医院的小儿IOIP病例,提示早期规范治疗是降低此病复发率的关键,尤其是儿童患者。

特发性眼眶炎性假瘤(idiopathic orbital inflammatory pseudotumor,IOIP)是仅次于甲状腺相关性眼病和眼眶血管瘤之后的第3大常见眼眶疾病。此例以无痛性眼部肿物首诊的炎性假瘤,且患儿年龄小,国内尚少见类似报道。
(A) Pretreatment images showed soft tissue swelling of the upper eyelid of the left eye (indicated by arrow) on T2, mild thickening of the superior rectus muscle of the left eye (indicated by arrow), and enlargement of the left lacrimal gland; (B) Post-treatment images showed that the swelling of the left eye rectus muscle, left upper eyelid and soft tissues was a brisk clinical improvement compared with that at admission (indicated by arrows), showing long T1 and long T2 signals.
