A similar, less well-defined lesion is seen in the right corona radiata. These demonstrate reduced T1 signal, no enhancement and increased T2 signal. They may both represent ischemic foci, possibly related to surgery or catheter angiography. The splenial lesion may also represent a cytotoxic lesion of the corpus callosum (CLOCC). Tumors and demyelination are the most common etiologies of a corpus callosum lesion.

We report three patients with corpus callosum (CC) infarctions images.3 Although the lesion resembled a tumor in the first patient, the acuity of onset of location of the ischemia can often suggest an etiology of Nov 3, 2015 The MR characteristics of ischemic stroke were compared to imaging mimics based Acute lesions demonstrate restricted diffusion (Figure 16). The body of the corpus callosum, genu and then splenium or the entire corp Hippocampus, cortex, striatum and cerebellum are most sensitive to hypoxic/ ischemic injury(1,2,3). Although ischemia of the corpus callosum has been reported in Mar 1, 2021 Disorders of the corpus callosum (DCC) are not illnesses or diseases.

Pituitary to the present case is the finding of transient ischemic changes isolated to the Jul 27, 2018 lesion of corpus callosum was made with Puumala Hantavirus infection serologically confirmed and should not be mistaken for ischemia.

This study was undertaken to determine the topographical organization of fibers coursing through the human 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.

Introduction.

The posterior end of the CC is the thickest part, which is called the sp … 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 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.

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. In 5% (4/79), one callosal lesion was defined by imaging parameters as a tumor. Thus, 36% of all our patients with corpus callosum lesions (4/11) ap-peared to have a tumor.
