目的探讨肥厚性硬脑膜炎的临床表现及磁共振影像特征。方法对3例肥厚性硬脑膜炎患者的临床表现与磁共振特征进行回顾性分析及文献复习。结果 3例均以头痛为首发症状,误诊为偏头痛,渐出现颅神经麻痹、肢体轻偏瘫。磁共振可见大脑镰、小脑幕、鞍旁硬脑膜结节状或条带状增厚,T1WI呈等或略低信号,T2WI呈低信号,增强后呈均匀强化。治疗后复查磁共振,增厚的硬脑膜变薄、消失,强化减轻。结论肥厚性硬脑膜炎临床少见,以头痛、脑神经麻痹等为主要症状,磁共振检查结果为临床诊断依据,治疗后影像学亦好转。
Objective To investigate the clinical manifestations and magnetic resonance imaging features of hypertrophic dura meningitis. Methods Three cases of hypertrophic dura meningitis patients with clinical manifestations and MRI features of retrospective analysis and literature review. Results All 3 patients had headache as their first symptom, misdiagnosed as migraine headache, cranial nerve paralysis gradually appeared, and limb hemiparesis occurred. MRI showed falx, cerebellar tentorium, parasellar nodular or ribbon thickening, T1WI was equal to or slightly lower signal, T2WI showed a low signal, enhanced uniform enhancement. After treatment review of MRI, thickened thickening of the dura, thinning, disappear, and strengthen to reduce. Conclusions Hypertrophic dura meningitis is rare, with headache and cranial nerve palsy as the main symptoms. The results of MR examination are the basis of clinical diagnosis, and the imaging is improved after treatment.
