颈部侧位X光肿块影像表现的扁桃腺周围脓疡(附病例报告)
Peritonsillar Abscess Presenting as a Mass Shadow on Lateral Neck Radiograph: A Case Report

背景：扁桃腺周围脓疡的影像学诊断方式以计算机断层为主，以颈部侧位X光片影像诊断的报告尚少，本文目的是报告一个可以用颈部侧位X光片诊断扁桃腺周围脓疡的方法。方法：我们回顾了扁桃腺周围脓疡的临床症状以及影像学诊断文献，对照我们所报告的病例，探讨更有效的诊断方法。结果：计算机断层扫描虽然对于扁桃腺周围脓疡仍然是很准确的诊断工具，但是颈部侧位的X光片结合临床症状有很好的诊断价值。结论：我们的观察发现，颈部侧位X光片对于诊断扁桃腺周围脓疡以及排除其它颈部感染，经济且快速，在临床上有非常好的诊断价值。
Background: Lateral neck radiograph is the most significant radiographic examination performed in a child with a suspected pharyngeal lesion. Methods: A 10-year-old boy suffered from severe sore throat with drooling and could not open mouth for 1 day. He complained of difficulty initiating swallowing even swallowing own saliva. Results: A lateral neck radiograph showed a mass shadow behind the posterior border of the mandibular ramus. Contrast-en- hanced CT showed a rim-enhanced hypodense mass (1.5 × 1.3 cm) at right superio-lateral tonsillar fossa. Endoscopy revealed a visible bulge of the right tonsil. Peritonsillar abscess was consequently diagnosed. Conclusions: A properly positioned lateral neck radiograph with a good imaging quality is a useful modality in the preliminary diagnosis of peritonsillar abscess.
