The aim of the study is to analyse the various parts of corpus callosum involved in the disease processes and the etiological predilection to corpus callosum.

The commissural fibers contained in various parts such as rostrum, genu, body and splenium of corpus callosum are affected by various disease process. It is commonly affected in various acquired disease process, the pattern of which may help decipher the etiology.

We analysed various patients whose MRI imaging revealed corpus callosum lesions. The part of the corpus callosum involved, the etiological predilection to the parts of corpus callosum, the etiology based on the part involved, and the clinical presentation was noted.
11 patients had involvement of corpus callosum. 7 patients were males and 4 were females. The rostrum was involved in 3, genu was involved in 4, body was involved in 5, and splenium was involved in 6. The various etiologies that contributed to the corpus callosum involvement was stroke (5), malignancy including glioblastoma and CNS lymphoma (2), systemic lupus erythematosus (SLE) (2), tumefactive demyelination (1) and infectious vasculitis (1). The most common site of involvement in stroke are splenium (4) followed by Genu (2), rostrum (2), and body (2). SLE patients with neuropsychiatric lupus had involvement of the splenium. The etiology of splenial involvement was SLE (2) and ischemic infarct (2). The etiology in involvement of body was infarct (2), tumefactive demyelination (1), infectious vasculitis (1), and malignancy (1). The associated areas that were involved included pericallosal area (2) and bifrontal involvement (2).

Splenium was the most common site of involvement in corpus callosum. The etiological description to various parts of corpus callosum is depicted with pictorial correlation
