Abstract

Objective: This case study aims to present the Foreign Accent Syndrome (FAS) in a patient with Cerebral Arteriovenous Malformation (cAVM), considering neuropsychological, radiological and microsurgical aspects.

Methods: The patient underwent preoperative neuropsychological assessment and MRI and Tractography were performed to identify fibers close to the lesion site. In the surgical procedure, a craniotomy was performed for excision of the cAVM. After surgery and 6 months after the surgical procedure, the patient underwent further and neuropsychological evaluations.

Results: The presence of AVM located in the posterior part of the medial surface of the left superior frontal gyrus was identified and the neuropsychological evaluation found cognitive deficits and symptoms characteristic of FAS, which disappeared after resection.

Conclusion: This report presented a case of cAVM in which symptoms were found even without rupture, which was no longer observed after the surgical procedure, demonstrating the relationship of cAVM with the symptoms and neuroanatomical bases of FAS.

脑动静脉畸形伴外国口音综合征1例。

目的本病例研究旨在从神经心理学、放射学和显微外科等方面介绍一例脑动静脉畸形（cAVM）患者的外国口音综合征（FAS）。方法对患者进行术前神经心理评估，并进行MRI和牵引描记术以识别病变部位附近的纤维。在手术过程中，进行了开颅手术以切除cAVM。手术后和手术后6个月，患者接受了进一步的神经心理学评估。结果发现左额上回内表面后部存在AVM，神经心理学评估发现认知缺陷和FAS症状，切除后消失。结论本报告报道了一例cAVM，即使没有破裂也能发现症状，但在手术后不再观察到，证明了cAVM与FAS的症状和神经解剖学基础的关系。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
