BACKGROUND
To the best of the authors' knowledge, this is the first case of microcystic/reticular schwannoma arising in the frontal bone.
OBSERVATIONS
An 18-year-old man presented to the authors' orthopedic clinic with a complaint of a progressively enlarging, painless mass in the frontal bone. It showed significant hyperintensity on T2-weighted imaging with progressive enhancement. Computed tomography combined with three-dimensional reconstruction showed expansive bone destruction with a soft tissue mass in the left side of the frontal bone, without calcification inside or a sclerotic margin around it. The mass was a microcystic/reticular schwannoma as confirmed by surgical pathology.
LESSONS
The authors report a rare case of a microcystic/reticular schwannoma arising in the frontal bone, with relatively comprehensive imaging data that enabled them to learn more about this tumor.
背景
据作者所知，这是首例发生于额骨的微囊性/网状神经鞘瘤。
观察结果
一名18岁男性因额骨处有一个逐渐增大的无痛性肿块而就诊于作者所在的骨科诊所。其在T2加权成像上表现为明显高信号且有渐进性强化。计算机断层扫描结合三维重建显示额骨左侧有膨胀性骨质破坏并伴有软组织肿块，内部无钙化且周围无硬化边缘。手术病理证实该肿块为微囊性/网状神经鞘瘤。
经验教训
作者报告了一例罕见的发生于额骨的微囊性/网状神经鞘瘤病例，并提供了相对全面的影像学数据，这使他们能够更多地了解这种肿瘤。
