BACKGROUND Intracranial chondroma is a rare benign tumor that more commonly arises from the skull base. Chondroma arising from the falx cerebri is very rare, with only 19 cases previously reported in the literature. The imaging characteristics of intracranial chondroma and meningioma can be similar. Surgical excision and histology are required for the diagnosis. This report is of a case of intracranial chondroma that includes the imaging findings. The methods of diagnosis, management, and prognosis are discussed. CASE REPORT A 44-year-old man presented with episodes of severe headache. Magnetic resonance imaging (MRI) showed a well-defined, extra-axial, parafalcine lesion in the right frontal region. An interhemispheric craniotomy was performed. A right frontal solid and calcified tumor attached to the falx cerebri was identified and removed. Histology confirmed the diagnosis of a benign chondroma containing areas of hemorrhage and cystic degeneration. CONCLUSIONS Chondroma arising in the falx cerebri is a rare intracranial tumor that may mimic meningiomas on imaging. Awareness of the varied imaging characteristics of these benign tumors is essential for planning the most appropriate treatment.
颅内软骨瘤是一种罕见的良性肿瘤，更常见于颅底。起源于大脑镰的软骨瘤非常罕见，文献中此前仅报道过19例。颅内软骨瘤和脑膜瘤的影像学特征可能相似。诊断需要手术切除和组织学检查。本报告介绍了一例颅内软骨瘤病例，包括影像学表现。讨论了诊断、治疗方法及预后。病例报告：一名44岁男性出现严重头痛发作。磁共振成像（MRI）显示右侧额叶区域有一个边界清晰的轴外、大脑镰旁病变。进行了半球间开颅手术。发现并切除了一个附着于大脑镰的右侧额叶实性钙化肿瘤。组织学证实为良性软骨瘤，伴有出血和囊性变区域。结论：起源于大脑镰的软骨瘤是一种罕见的颅内肿瘤，在影像学上可能类似脑膜瘤。了解这些良性肿瘤多样的影像学特征对于规划最合适的治疗至关重要。
