An intracranial chondroma is uncommon; however, a falx chondroma is rare. We report on a 26-year-old woman who had had a history of intermittent headaches for 10 years. Two weeks before admission, a brain tumor was incidentally found on a computed tomography scan after a motor vehicle accident. On admission, she was alert and had no neurological deficits. Magnetic resonance imaging of the brain revealed a multilobular, ring-shaped, well-defined tumor at the anterior falx. The tumor involved both sides of the falx and extended to the bifrontal area. She underwent surgery and the tumor was totally excised. She recovered well after the operation. The pathology revealed a chondroma. To the best of our knowledge, only 14 cases of intracranial chondromas derived from the falx have been reported. In this report, we discuss the pathogenesis, differential diagnosis in imaging studies, treatment, and prognosis of a falx chondroma.
