Review Case Reports
Acute Marchiafava-Bignami disease with extensive diffusion restriction and early recovery: case report and review of the literature.
Marchiafava-Bignami disease (MBD) is a neurological disorder that has been found to be associated with chronic alcoholism and malnutrition. MBD classically results in acute edema and demyelination of the corpus callosum. ⋯ We present an acute onset of MBD with diffusion restriction of the complete corpus callosum and symmetric bilateral extension into the semioval center, that almost completely resolved clinically as well as in MRI only 3 days later. With early detection and treatment, the prognosis of MBD may be good even in cases with severe diffusion restriction of the complete corpus callosum.

To determine whether voxel-based morphometry of the cerebrospinal fluid (CSF) space can accurately differentiate iNPH from other related neurological disorders. ⋯ The VBM-based CSF space analysis can detect disproportionate changes in CSF space and differentiate iNPH patients from those with AD or PD and healthy elderlies accurately.

The detection rate of typical transient global amnesia (TGA) lesions on diffusion-weighted imaging (DWI) can be improved, up to 85% with optimal DWI parameters and imaging time. There is limited evidence that these findings are similar to those observed in large-scale consecutive patients with TGA in clinical practice. ⋯ A modified TGA DWI protocols for detecting TGA lesions are useful in large-scale clinical practice for confirming the diagnosis of TGA patients with clinical findings.

Bilateral paramedian thalamic infarction is a rare subtype of stroke the etiology of which still remains undetermined in many patients. ⋯ Vascular imaging is useful to determine underlying vascular pathologies and may support the diagnosis of small vessel disease in those patients with isolated bilateral paramedian thalamic infarction, hypoplastic/absent P1 segment of the PCA, and lack of vascular pathology.
