We report a patient who presented with sudden onset instability and diplopia. On neurological examination he had asymmetrical asterixis, predominantly in the left hand, and ocular findings consistent with a pretectal syndrome. He was also unable to stand or even sit up unassisted, with a tendency to tilt his body and rotate his trunk axis to the left. Brain MRI showed a hemorrhage in the right thalamo-mesencephalic junction. This region involves important structures for the control of postural stability, motor control, ocular movements and vestibulo-ocular integration, not yet well understood. To our knowledge, this is the first reported case with the simultaneous combination of astasia, prectectal syndrome and asymmetrical asterixis.

Marchiafava-Bignami disease (MBD) is a rare alcohol-associated disorder. Clinical features include not only disturbed consciousness, dysarthria, tetraparesis, astasia-abasia, and symptoms of interhemispheric disconnection as initial symptoms but also cognitive deficits as clinical outcomes. The clinical significance of cerebral microhemorrhage (CMH) has been recognized in patients with cognitive deficits; however, the presence of CMH in patients with MBD has not been emphasized. The aim of the present study was to clarify the relationship between CMH and MBD. For this purpose, we report four patients with MBD, who showed asymmetrical hypointense areas in multiple cortico-subcortical regions on susceptibility-weighted imaging (SWI). All cases had a history of chronic alcohol abuse and symmetrical lesions in the entire corpus callosum. These patients' clinical symptoms included not only coma, dysarthria, and astasia-abasia as initial symptoms but also dementia as a clinical outcome. SWI showed asymmetrical hypointense areas in the multiple cortico-subcortical regions, indicating the presence of CMH. Compared with patients with normal cognitive function, demented patients showed higher severity of CMH. Our report would indicate that CMH is an important factor indicating the severity of dementia in patients with MBD.

Marchiafava-Bignami disease is a rare alcohol-associated disorder. Clinical features include not only disturbed consciousness, dysarthria, tetraparesis, and astasia-abasia as initial symptom but also cognitive deficits and symptoms of interhemispheric disconnection as clinical outcomes. The clinical significance of cerebral microhemorrhage has been recognized in patients with cognitive deficits. We have recently examined the clinical significance of cerebral microhemorrhage in Marchiafava-Bignami disease and demonstrated that demented patients showed higher severity of cerebral microhemorrhage than patients with normal cognitive function. However, the relationship between callosal lesions and cerebral microhemorrhage in Marchiafava-Bignami disease has not been fully examined. The aim of the present study was to clarify the relationship between callosal lesions and cerebral microhemorrhage in Marchiafava-Bignami disease. For this purpose, we report four patients with Marchiafava-Bignami disease. All cases had a history of chronic alcohol abuse and symmetrical lesions in the corpus callosum. Clinical symptoms include not only coma, dysarthria, and astasia-abasia as initial symptom but also dementia as clinical outcomes. Susceptibility-weighted imaging showed asymmetrical hypointense areas in the multiple cortico-subcortical regions, indicating the presence of cerebral microhemorrhage. There were no apparent relationships between the extension of callosal lesion and the severity of cognitive deficits or cerebral microhemorrhage. Our present report indicates that cerebral microhemorrhage, an important. factor for the severity of dementia in Marchiafava-Bignami disease as clinical outcomes, is independent of the callosal lesion.
