Here, we report a case of 26-yearold male, with a huge mass at fronto-parietal falx cerebri, who was misdiagnosed as parafalcine meningioma on preoperative MR imaging. After surgery, the diagnosis of chondroma was confirmed pathologically. By reviewing the MR images of the patient, we find that the peripheral ring-like enhancement and intratumoral partial slight coral-like enhancement on contrast-enhanced T1 images might be the valuable MR features to differentiate from parafalcine meningioma. In addition, the tumor’s pathogenesis and pathological characteristics were briefly discussed. Keywords : Intracranial chondroma, Falx cerebri, MR imaging
