Abstract:
Objective To analyze the CT and MRI manifestations of congenital cholesteatoma of petrous bone ,and evaluate the efficacy of it in the clinical practice.Methods Imaging findings in 27 pathological-proved cases were review. Imaging materials included CT scan in 26,MRI scan in 11.Results Petrous bone wall erosion and expanding tumor was observed with CT(n=23),tumor was not oberved with CT(n=3).Congenital choleseatoma signal intensity was intermediate or low on T 1W images and high on T 2W images in 11 cases.Conclusion The role of MRI and CT is affirming in the evaluation of congenital choleseatoma of the petrous bone. MRI is superior to CT for the evaluations of involvement of the membranous labyrinth and intracranial structures.
