胼胝体梗死

Callosal infarction

胼胝体的血液供应丰富，功能复杂，梗死发生率低。胼胝体梗死的危险因素和病因与其他部位梗死无异。该病的临床表现复杂多样，2个经典的临床表现为胼胝体离断综合征和额叶型步态障碍，但临床上以偏瘫、单瘫、失用和智力障碍等多见。CT平扫阳性率低，MRI对胼胝体梗死具有较高的敏感性和特异性。结合病史和影像学检查，胼胝体梗死的诊断并不困难，但需与其他易累及胼胝体的疾病相鉴别。多数胼胝体梗死患者的预后良好。

he blood supply of corpus callosum is rich, its function is complex, and the incidence of infarction is low. The risk factors and etiology for callosal infarction do not have any difference with the infarction in other parts of the brain. The clinical manifestations of the disease are complex and diverse. The two classical clinical manifestations are callosal disconnection syndrome and frontal-type gait disorder, but hemiplegia, monoplegia, apraxia, and mental retardation are common in clinical practice. The positive rate of CT scan is lower. MRI has higher sensitivity and specificity for callosal infarction. The diagnosis of callosal infarction is not difficult according to the history and imaging examination, however, it needs to be differentiated with other diseases that likely involve corpus callosum. Most of the patients with callosal infarction have good prognosis.
