BACKGROUND
Chondromas are benign cartilaginous tumors that are rarely seen in the brain.
OBSERVATIONS
A 58-year-old woman had undergone routine brain imaging after a motor vehicle accident and was incidentally found to have a right falcine lesion. Contrast magnetic resonance imaging showed a mostly nonenhancing mass with discontinuous rim enhancement. She was taken to the operating room and pathology revealed a chondroma.
LESSONS
Falcine intracranial chondromas are rare and typically misdiagnosed as meningiomas. Chondromas should be in the differential for patients presenting with nonenhancing falcine lesions.
背景
软骨瘤是一种罕见于脑内的良性软骨肿瘤。
观察结果
一名58岁女性在机动车事故后接受了常规脑部成像检查，偶然发现右侧大脑镰有一病变。增强磁共振成像显示一个大部分无强化的肿块，边缘有间断强化。她被送往手术室，病理检查显示为软骨瘤。
经验教训
大脑镰颅内软骨瘤罕见，通常被误诊为脑膜瘤。对于出现无强化大脑镰病变的患者，应将软骨瘤列入鉴别诊断范围。
