Stuttering is a disorder in the rhythm of speech characterized by an involuntary repetition, prolongation, and cessation of sounds. Neurogenic acquired stuttering is a very rare disorder which could result from different conditions with the involvement of several brain locations.
A 16-year-old male presented to our Hospital with headache associated with blurred vision followed by right-sided facial and upper limb tingling, clumsiness of right arm, and a complete inability to formulate language which evolved in the next minutes into an intense speech disorder characterized by persistent stuttering. Urgent brain magnetic resonance imaging showed a prominence of venous vasculature in left hemisphere in susceptibility weighted imaging sequence. A fluorodeoxyglucose-positron emission tomography revealed a bilateral occipital, temporal, and parietal hypometabolism. With the suspicion of migraine aura, analgesic treatment was administered. Symptoms progressively resolved inside 10 hours. Five months later he experienced a similar episode.
This case report represents a diagnostic challenge and suggests the inclusion of stuttering within the neurological manifestations of higher cortical dysfunction that can be found as a result of migraine aura.
口吃是一种言语节律障碍，表现为声音的不自主重复、延长和停顿。神经源性获得性口吃是一种非常罕见的障碍，可能由涉及多个大脑部位的不同情况引起。
一名 16 岁男性因头痛伴视力模糊就诊，随后出现右侧面部和上肢刺痛、右臂笨拙，以及几分钟后无法说话，导致严重的言语障碍，表现为持续口吃。紧急脑部磁共振成像显示左半球磁敏感加权成像序列中静脉血管突出。氟脱氧葡萄糖正电子发射断层扫描显示双侧枕叶、颞叶和顶叶代谢低下。考虑到偏头痛先兆的可能性，给予了镇痛治疗。症状在 10 小时内逐渐缓解。五个月后，他经历了类似的发作。
本病例报告代表了一个诊断挑战，并提示口吃可能是偏头痛先兆导致的高级皮质功能障碍的神经表现之一。
