Abstract
BACKGROND: Primary intracranial myxomas (PIMs) are extremely rare benign tumors which arise from skull base. The aim of this study was to characterize the radiologic manifestation of PIMs in a series of 14 cases.
METHODS: We reviewed the imaging and clinical data in 14 patients with pathologically proven PIMs. Assessed features of lesions include the shape, margin, bony destruction, attenuation and/or signal intensity, and pattern of enhancement.
RESULTS: Extremely high density foci indicating calcification or bony debris within the tumors were observed in 5 cases on CT images. On MR images, the tumors demonstrated heterogeneous hypo-intensity on T1WI and hyper-intensity on T2WI. A honeycomb pattern on enhanced T1WIs was observed in 63.6% (7 /11) of the cases.
CONCLUSION: Radiologic findings of PIMs include calcified foci or bone debris on CT, heterogeneous hypointensity on T1WI and predominantly hyperintensity on T2WI, and honeycomb appearance on enhanced T1WI.
