Abstract
Background: a variety of entities that arise from different causes such as congenital, inflammatory, tumoral, degenerative, infectious, metabolic, traumatic, vascular and toxic agents. The corpus callosum, or a specific part of it, can be affected selectively.
Aim of the Work: The aim of this study is to emphasize the role of MRI modalities in the proper evaluation of the different pathological entities of the corpus callosum.
Patients and Methods: This study was conducted on 73 patients 37 male , 36 female , Their age ranging from one day old to 78 years old.
The study was done on a GE MRI machine 1.5 tesla in Ain shams university specialized Hospitals at the period between 2016 and 2019.
Images from the MRI studies were evaluated by two neuroradiologists
Results: our study revealed many pathological entities including inflammatory (42.5%), Vascular (26.0%), Congenital (15.1%), Tumoral (11.0%), Misc (2.7%), Metabolic (1.4%) and Infectious (1.4%) of Different callosal lesions.
Conclusion: Our data and in agreement with the previous studies has demonstrated that MRI is a valuable diagnostic tool for patients with corpus callosal lesions , utilizing contrast enhanced sequences as well as new MRI sequences such as Cube FLAIR , Spectroscopy , DTI and CSF flowmetry sequences . MRI has also shown to be useful and capable in the follow up of patients with demyelinating diseases with accurate depiction of the disease progression in space and in time (extent of the disease and stage of activity).
