Yamada等人报告了MR纤维束造影术，描述了一名持续性左半球卒中患者的左半球弓状束损伤与推测的传导性失语症相关。1我们同意作者的发现，即左弓状束被病变吞没，但不同意这一结论支持传导性失语症的特异性诊断，弓状束损伤与失语症的发生有必然联系。这些区别从启发式和临床的角度来看都很重要。区分传导性失语与其他形式的失语是一个临床过程，而不是一个成像过程，Geschwind的断开模型的经典病变位置...
Yamada et al. reported MR tractography depicting damage to the left hemisphere arcuate fasciculus in association with presumed conduction aphasia in a patient who had sustained left hemisphere stroke.1 We concur with the authors’ findings that the left arcuate fasciculus is engulfed by the lesion, but disagree with the implications that this supports a specific diagnosis of conduction aphasia, and that the damage to arcuate fasciculus is necessarily associated with the aphasia in this patient. These distinctions are important from both heuristic and clinical perspectives. Distinguishing conduction aphasia from other forms of aphasia is a clinical process, not an imaging one, and the classic lesion locations of Geschwind’s disconnection model of …
