目的 :探讨咽旁间隙脂肪瘤的临床特点及诊治原则。方法 :回顾 3例咽旁间隙脂肪瘤临床资料并回顾相关文献。结果 :咽旁间隙脂肪瘤常表现为无痛性肿物 ,症状有堵塞感、吞咽困难、咽异物感。CT显示为边界清晰 ,均匀低密度灶。MR上T1W及T2W均呈高信号 ,增强后未见显著强化。所有病例均采用颈侧切开进路切除肿瘤 ,术后经 6个月 -5年随访 ,未见复发。结论 :CT与MR有助于咽旁间隙脂肪瘤的诊断 ,治疗应首选颈侧切开进路手术切除。
Objective: To investigate the clinical features and diagnosis and treatment of parapharyngeal space lipoma. Methods: Three cases of parapharyngeal space lipoma were retrospectively reviewed. Results: Parapharyngeal space lipoma often showed painless mass, the symptoms of clogged, dysphagia, pharyngeal foreign body sensation. CT showed a clear boundary, uniform low-density stove. Both T1W and T2W in MR showed high signal, and no significant enhancement was seen after enhancement. All cases were treated by neck incision approach to remove the tumor, after 6 months - 5 years follow-up, no recurrence. Conclusion: CT and MR are helpful for the diagnosis and treatment of parapharyngeal space lipoma. The neck and lateral incision should be the best choice for the surgical treatment.
