Intrapulmonary schwannoma is uncommon and preoperative radiological diagnosis is rare. Described is a schwannoma that developed as a pulmonary hilar nodule in a 38-year-old woman. The nodule showed strong (18)F-fluorodeoxyglucose uptake with a maximum standard uptake value of 5.98 on positron emission tomography and had a high apparent diffusion coefficient (2.5 × 10(3) mm(2)/s) on diffusion-weighted magnetic resonance imaging. Combination of these functional imaging techniques warrants further evaluation in radiological diagnosis of intrapulmonary schwannoma.
肺内 schwann 瘤并不常见，术前影像学诊断较为罕见。本文报道了 1 例 38 岁女性患者，肺门结节为 schwann 瘤。该结节在正电子发射断层扫描（PET）上摄取 18F-氟脱氧葡萄糖（FDG）明显，最大标准摄取值（SUVmax）为 5.98；磁共振扩散加权成像（DWI）上表观扩散系数（ADC）值较高（2.5×10(3)mm(2)/s）。这些功能成像技术的结合有望进一步提高肺内 schwann 瘤的影像学诊断价值。
