Diagnosis Of CT And MRI In Intracranial Lipoma

Objective To evaluate the value of CT and MRI in the diagnosis of intracranial lipoma. Methods 10 cases of intracr anial lipoma were analyzed in comparing their CT and MRI manifestations with their operating pathology. Results Tumors are located in corpus callosum in 8 cases,in third ventricle of cerebrum in 1 and in lateral sulcus in 1.3 cases of lipoma in corpus callosum are accompanied by lipomas in choroid plexus of bilateral ventricles,rarely.Their CT manifestations are even low density area in 7 cases,not even in 3 and calcified tumors in 3.Tumors in 3 cases examined with MRI are high intensive signal in T1WⅠ and T2WⅠ. Conclusion :Lipomas may be diagnosed with CT manifestations as different-shape low density area in corpus callosum,negative CT value or accompanying tumor calcified,and MRI manifestations as high intensive signal in T1WⅠ and T2WⅠ.
