Learning objectives Summarize the anatomical and functional aspects of the corpus callosum. Describe the main etiologies of corpus callosum lesions, illustrate the MRI and CT appearance of these lesions, and discuss the importance of these imaging features in clinical diagnosis and treatment.
Read more Background The corpus callosum (latin term "tough body"), consisting of more than 200 million myelinated nerve fibers, is the brain's largest white matter structure. It is a bundle of nerve fibers that connects and allows communication between the two hemispheres to perform various motor and cognitive functions (Kendra Cherry, 2023). The dense composition of the white matter tracts in relation to surrounding hemispheric white matter creates a barrier to disseminating various common pathological processes (Eric C. Bourekas, 2002).
Read more Findings and procedure details The main etiologies of corpus callosum lesions include neoplasm, vascular, trauma, infection, demyelination, and others (3). Consequently, due to this dense white matter tract, only highly aggressive tumors (glioblastoma, lymphoma), typically involve the corpus callosum (Eric C. Bourekas, 2002).Agenesis of the corpus callosum (Figures 1 and 2) is one of the most common congenital brain malformations. It is characterized by the complete or partial absence of the corpus callosum. This condition is not linked to specific functional or behavioral abnormalities,...
Read more Conclusion The corpus callosum, often dubbed "the tough body," plays a vital role as a complex anatomical and functional structure in the brain. In this poster, we showcase a range of corpus callosum lesions frequently observed in clinical practice, emphasizing their critical impact on patient health and outcomes. A deep understanding of the imaging patterns associated with these lesions is essential for optimizing treatment strategies and significantly enhancing the quality of life for patients.
