胸片偶然发现胸腔病变的 11 岁哮喘女孩
一名 11 岁哮喘女孩因发热、气促和干咳 5 天就诊，家庭吸入剂和退热药控制不佳。胸片偶然发现右肺尖光滑软组织密度影，MRI 进一步显示病变约 3.5 cm，起源于 T1 出口孔并突入右肺尖，符合良性神经鞘瘤。
要点
- 胸片示右肺尖光滑软组织影，与邻近肺实质呈钝角，提示肺外来源。
- 第一肋变薄和重塑但无侵蚀，提示病变长期存在且非侵袭性。
- MRI 显示病灶直径约 3.5 cm，起源于 T1 出口孔，符合良性神经鞘瘤。
核心结论
- 右肺尖病变经 MRI 诊断为起源于 T1 出口孔的良性神经鞘瘤。
研究设计与样本
- 个案报告：11 岁哮喘女孩，发热、气促、干咳 5 天。
主要发现
- 胸片示右肺尖光滑软组织密度影，与邻近肺实质呈钝角，提示肺外来源。
- 第一肋变薄和重塑但无侵蚀，提示病变长期存在且非侵袭性。
- MRI 示病变最大径约 3.5 cm，起源于 T1 出口孔并突入右肺尖。
关键数值与推荐
- 病变与邻近肺实质呈相对钝角提示肺外来源。
- 第一肋变薄和重塑但无侵蚀提示长期非侵袭性病变。
- MRI 示病灶最大直径约 3.5 cm，起源于 T1 出口孔。
临床怎么用
- 对胸片偶然发现的肺尖病变，钝角征和邻近肋骨重塑可辅助判断来源与性质。
- 疑似神经源性病变时可行 MRI 明确起源和范围。

An 11-year-old girl with asthma presented with 5 days of fever, shortness of breath and dry cough. Her symptoms had not been controlled at home despite inhalers and anti-pyretics. The respiratory examination was unremarkable aside from a left-sided middle zone wheeze. There were no focal neurological deficits or neurocutaneous stigmata on examination. Chest radiograph ( figure 1 ) showed a smooth soft-tissue density projected over the right apex. The relatively obtuse angle between the lesion and the adjacent lung parenchyma suggested the lesion originated outside the lung, as opposed to originating within the lung parenchyma. Thinning and remodelling, but not erosion, of the first rib suggested the lesion was longstanding and non-aggressive. Subsequent characterisation via MRI ( figure 2 ) demonstrated a well-defined lesion with a maximum diameter of approximately 3.5 cm, arising from the T1 exit foramen and protruding into the right lung apex, consistent with a benign nerve sheath...
