64-year-old male patient with curvilinear type pericallosal lipoma and partial corpus callosal agenesis. T1-weighted axial (A) and sagittal (B) images show hyperintense lipoma (arrows) superior and posterior to corpus callosum. Splenial portion is not fully developed. - "Splenial Lesions of the Corpus Callosum: Disease Spectrum and MRI Findings" Corpus callosum lesions have a broad differential diagnosis, with the greatest concern for a neoplasm in an elderly patient. The most common tumors affecting the corpus callosum are glioblastoma multi-forme (GBM) and lymphoma.

It is important to recognize these lesions for what they are—secondary lesions. It is also important to be familiar with their known causes so that the source can be found and addressed and so that a misdiagnosis of ischemia can be avoided.

The most common cause of corpus callosum infarction probably was embolism. The 20 ischaemic lesions were asymmetrical but adjacent to the midline; the latter was involved in new or large lesions. Diffuse axonal injury commonly resulted in large lesions, which tended to be asymmetrical; the midline and borders of the corpus callosum were always involved. Lesions of the Corpus Callosum Multiple sclerosis—Multiple sclerosis (MS) is the most common demyelinating disorder, with presumed autoimmune and inflammatory causes. CT has a low positive predictive value for detection of MS lesions. On MRI, the disease is T2 and FLAIR hyperintense, with con-trast enhancement in the acute stage. Lesions of the corpus callosum can present a diagnostic dilemma, both for the radiologist and the clinician.

Ischemic lesion corpus callosum

Lesions in the forepart of the corpus callosum were more common in patients with MS (69.7%) than patients with NMOSD (51.6%) or ADEM (22.2%). Patients with NMOSD (77.4%) more often had lesions in Corpus callosum is Latin for “tough body,” and the corpus callosum is the largest connective pathway in the brain, being made up of more than 200 million nerve fibers. Very occasionally, a The end part of the corpus callosum, towards the cerebellum, is called the splenium. This is the thickest part, and overlaps the tela choroidea of the third ventricle and the midbrain, and ends in a thick, convex, free border.

The posterior end of the CC is the thickest part, which is called the splenium. BACKGROUND: Reversible splenial lesion syndrome (RESLES) is a newly recognized syndrome, and a reversible progress associated with transiently reduced diffusion lesion in the splenium of the corpus callosum (SCC) is the typical pathological finding. The routine clinical symptoms include mildly altered states of consciousness, delirium, and seizures.

It has been hypothesized that a GBM can lead to ischemia by causing a procoagulant state or by compression of cerebral arteries by tumor. Summary: Infarcts of the corpus callosum have not been well documented in the radiologic literature. We present five cases that were unusual in either their clinical or radiologic presentation or both. Biopsies were performed in three of the five cases, and in time, all lesions evolved in a pattern consistent with infarct. Recognition of the varied clinical and radiologic presentation of Ischemic.
