callosum are rare and may represent transient responses to injury or myelination abnormalities. More common butterfly lesions involve the corpus callosum and both cerebral hemispheres—a pattern associated with aggressive tumors, demyelination, and traumatic brain injury. Unenhanced CT is a first-line neuroimaging modality.

monoxide poisoning or ECG changes or cardiac ischemic indicators plus CO-Hb hyponatraemia can lead to membrane damage in brain cells (myelin lesions), cause damage to the white substance in the brain near the corpus callosum.

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 Cytotoxic lesions of the corpus callosum (CLOCCs) represent a collection of disparate conditions that can cause signal change in the corpus callosum, usually involving the splenium. With other infectious diseases, the involvement of the corpus callosum is typically transitory; however, in the setting of COVID-19, this has yet to be determined. 6, 16 The patient also had ischemic changes in other parts of the brain, and an alternative consideration is a stroke of the corpus callosum.

We correlated the distribution of Wallerian degeneration in the corpus callosum with the anatomical sites of focal cortical lesions due to ischemic infarctions or circumscribed contusions. Literature regarding callosal injury after hypoxic-ischemic injury (HII) is scant. To present the MRI and US findings of callosal injury after HII. MRI and US studies of 76 neonates were evaluated for HII and 53 were considered positive. Of the 53 neonates with HII, 40 demonstrated restricted diffusion on DWI; of these, 30 revealed callosal involvement. Nine of the 13 neonates with normal DWI lesions of the callosum are uncommon and midline ischemic lesions are rare [1-3]. In contrast, MRI lesions of the corpus callosum have been reported in situations of trauma, in-flammation, malignancy, metabolic disorders, infections and toxic exposure [3-6].

We performed this study to clarify the clinical and radiological implications in patients with SCC lesions.

However, the clinical implications of this lesion are unclear and are not always consistent with ischemic infarctions. We performed this study to clarify the clinical and radiological implications in patients with SCC lesions.

In contrast, MRI lesions of the corpus callosum have been reported in situations of trauma, in-flammation, malignancy, metabolic disorders, infections and toxic exposure [3-6]. The brain regions thought to be most sensitive to hypoxic/ischemic injury are the CA1

Discussion Bilateral strokes of the corpus callosum are uncommon because of the rich blood supply of this structure from 3 main arterial systems: namely, the anterior communicating, anterior cerebral, and posterior cerebral arteries. 1 Also, the corpus callosum is a dense white matter tract, which makes it less sensitive to ischemic injury than gray matter. anterior and posterior cerebral arteries, ischemic injury of the corpus callosum is not common. Although vascular lesions involving corpus callosum are not common, congenital vascular anomalies, acquired traumatic and nontraumatic corpus callosal ischemic or hemorrhagic lesions may occur. Imaging findings OR Procedure details Cytotoxic lesions of the corpus callosum were classified into 2 types: a small type localized in the splenium in 26 cases (78.9%) and a large type spread along the ventricle in 7 cases (21.2%). The severity of SAH, coiling, hydrocephalus, and poor mRS score at discharge were significantly higher in the group with cytotoxic lesions of the corpus callosum.

Corpus callosum lesions in NMO preferentially involve the splenium. Compared with those in MS , they are larger, more confluent, more edematous, and more heterogeneous.

Feb 6, 2017 Radiologists should be familiar with the imaging appearance of CLOCCs to avoid a misdiagnosis of ischemia. When CLOCCs are found, the

isolated MRI lesion of the splenium may represent vasospasm in the setting of pituitary apoplexy. Splenial lesions have been described in many different clinical scenarios. Etiologies include vascular, demyelinating, inflammatory, traumatic, neoplastic, infectious, and toxic/ Lesions in the splenium of corpus callosum The injuries to CC can have several etiologies, such as gliomas, lymphomas, infections, desmielinizated plates, associated, for example, with multiple sclerosis and although less frequently, ischemic lesions (rich collateral circulation) and iatrogenic lesions after surgical approaches (infratentorial ISCHEMIC: ischemic lesions are uncommon because of the rich blood supply of CC and relatively less sensitivity to ischemic injury than GM. Usually ischemic lesions are observed in patients with generalized atherosclerotic disease and/or other risk factors (hypertension, diabetes mellitus). Solitary infarcts are uncommon and usually associated found that focal lesions in the corpus callosum occurred in 14% of 79 patients with an available magnetic resonance imaging scan.

The lesions can be classified according to underlying pathophysiology 4-6. The most susceptible location of ischemic corpus callosum lesion was the splenium.

Background: Brain MRI may unexpectedly display abnormalities in splenium of the corpus callosum (SCC). However, the clinical implications of this lesion are unclear and are not always consistent with ischemic infarctions. We performed this study to clarify the clinical and radiological implications in patients with SCC lesions.

Lesions of the corpus callosum are uncommon and arise from multiple different etiologies. The lesions can be classified according to underlying pathophysiology 4-6.
