A 24-year-old woman was referred to us for an intracranial haemorrhage in the left temporal lobe caused by a ruptured cavernous malformation; the bleeding extended over the left Heschl's gyrus and Wernicke area. On admission, the patient had global aphasia. A few days later, she spontaneously improved but remained with mild residual comprehensive dysphasia. She reported hearing, in her right ear, recently heard words, which is consistent with palinacousis. Auditory acuity testing was normal. EEG showed focal slowing in the left temporal region with no epileptiform activity. During awake surgery for resection of the cavernous malformation, stimulation of the superior temporal gyrus did not provoke palinacousis. The patient made good recovery with complete resolution of the aphasia and no recurrence of palinacousis. We aimed to review this phenomenon and to provide a systematic review of the current literature.
一位 24 岁女性因左颞叶海绵状血管畸形破裂导致颅内出血，被转至我们医院；出血延伸至左侧海氏回和韦尼克区。入院时，患者表现为完全性失语。几天后，她自发性恢复，但仍遗留轻度全面性构音障碍。她报告说，她的右耳最近听到了一些声音，这与幻听一致。听觉敏锐度测试正常。脑电图显示左颞区局灶性减慢，无癫痫样活动。在清醒状态下切除海绵状血管畸形的手术中，刺激颞上回并未引起幻听。患者恢复良好，完全恢复了语言功能，且未再出现幻听。我们旨在回顾这一现象，并对当前文献进行系统综述。
