바이러스성 뇌염 이후 청력 소실과 함께 발생한 음악 환각증의 단일광자방출전산화단층촬영 소견 1례 = A Case of Single Photon Emission Computerized Tomographic Finding in Patient with Acquired Deafness and Musical Hallucinosis after Viral Encephalitis

다국어 초록 (Multilingual Abstract)

Musical hallucinosis is uncommon symptom in the province of neuropsychiatry. Musical hallucinosis is often accompanied with hearing impairment caused by physical illness and is characterized by no psychotic symptoms. In the previous study, musical hallucinosis is related with secondary language center which paly a important roll in cognition and imagination of music and also related with activation of temporal lobe and frontal lobe. We report the case of musical hallucinosis with hearing impairment subsequent viral encephalitis. This case is activated both inferior temporal lobe and borderline of left temporal lobe and occipital lobe in the Single Photon Emission Computerized Tomography (SPECT). We predict that the result should be helpful to understand musical hallucinosis and auditory hallucination of schizophrenia.

국문 초록 (Abstract)

음악 환각증은 정신과 또는 신경과 영역에서 드물게 관찰되는 증상이다. 음악 환각증은 특히 신체적 질환에 의해 발생한 청력의 손실 이후 발생하는 경우가 많으며 정신증적 증상을 동반하지 않는 특징을 가진다. 기존의 보고에 따르면 이러한 음악 환각증은 음악을 인식하고 상상하는데 있어 중요한 역할을 하는 이차성 언어중추와 연관이 있는 것으로 보고되었으며 측두엽, 전두엽의 활성과도 관련이 있는 것으로 보고되었다. 저자들은 바이러스성 뇌염 이후에 발생한 청력 소실과 이에 동반된 음악 환각증을 보인 증례를 경험하였기에 이를 보고하고자 한다. 본 증례에서 시행한 단일광자방출전산화단층촬영(Sin-gle Photon Emission Conputerized Tomography：SPECT) 소견상 좌측 측두엽과 후두엽의 경계지역 및 양측 하부 측두엽의 활성을 보였다. 이러한 소견은 음악 환각증 뿐만 아니라 정신분열병의 환청을 이해하는데 도움을 줄 것으로 예측하였다.
