Imaging Findings and Diagnosis of Intradiploic Meningioma

Objective: To assess the imaging finding of CT and MRI in intradiploic meningioma of skull. Methods: The clinical symptoms, pathological type and imaging finding of two cases were analyzed. Results: One of the intradiploic meningioma was located in the frontal temporal bone and the pathological type was clear cell meningioma. Its imaging finding of CT showed osteogenic destruction and the skull was thicken, edge is coarse. Another was located in parietal bone and the pathological type was Epithelial type. Its imageology was lytic bone destruction and T1 WI showed low signal or equisignal intensity, T2 WI was equisignal intensity. The signal of enhance scan improved significantly. Conclusion: CT and MRI can play an important role in diagnosing intradiploic meningioma. The size and surroundings of tumor can show by them accurately.
