Abstract:
Objective To investigate the MRI manifestations of cerebral glioma involving corpus callosum,and to enhance the ability to diagnosis and differential diagnosis.Methods Thirty four cases of cerebral glioma involving corpus callosum under went plain and Gd DTPA enhanced MR scans.The MRi findings of these gliomas were compared with operation and pathology.Results Gerebral gliomas involving corpus callosum presented as long T 1 and long T 2 homogeneous or inhomogeneous signal intensity and obvious mass effect.The MRI findings of Gd DTPA enhanced MR scans were obvious enhancement,slight enhancement or no enhancement accouding to different pathological kinds of gliomas."Butterfly signs" and "semi butterfly signs" were the reflections when gliomas of corpus callosum invaded two sides or one side of cerebral hemisphere.These two signs were significant markings in the diagnosis of cerebral gliomas in corpus callosum region.Conclusions Cerebral gliomas involving corpus callosum are intracranial tumors with special location.MRI has significant clinical value in the diagnosis and differential diagnosis of this kinds of tumour.
