Abstract:
Objective To summarize and study the features of intracranial chondroma on CT and MRI imaging.Methods CT and MRI findings of ten cases of intracranial chondroma proved by surgery and pathology from 1994.1 to 2004.9 were retrospectively analyzed.Results Among 10 cases, 4 cases were located at the skull base, 4 cases at convexity, 1 case at the region of falx cerebri, and 1 case within the brain parenchyma.CT scans showed obvious calcification and clear border of the tumors in 10 cases, mixed attenuation in 9 cases, and adjacent bone invasion in 5 cases.4 cases of MRI scans showed hypointense signal on T1 and T2-weighted images in calcified element of the tumor, intermediate to hypointense signal intensity on T1-weighted image, and hyperintense signal intensity on T2-weighted image in parenchyma of the tumor.4 cases of CT scans showed slightly enhancement.Conclusion Intracranial chondroma are often originated from synchondrosis of the skull base, convexity of brain and region of falx cerebri. Obvious calcification may be seen in most cases. Slightly enhancement and marked delayed contrast enhancement were characteristic. The accurate diagnosis still depends on pathology.
