Organic mania has been reported to have multiple etiologies. A case is described of a patient who developed mania following a coronary artery bypass graft and mitral valve replacement. Cerebral abnormalities were not detected by computed tomographic or magnetic resonance imaging scans, but an area of dysfunction was found using single photon emission computed tomographic (SPECT) imaging. The lesion resolved when the patient became clinically asymptomatic. The area of decreased cerebral perfusion associated with the patient's mania was in an atypical location, raising questions about which brain regions can result in well-defined psychiatric syndromes.
据报道，器质性躁狂有多种病因。本文描述了一例患者，该患者在冠状动脉搭桥术和二尖瓣置换术后出现躁狂。计算机断层扫描或磁共振成像扫描未检测到脑部异常，但使用单光子发射计算机断层扫描（SPECT）成像发现了一个功能障碍区域。当患者临床无症状时，该病变消失。与患者躁狂相关的脑灌注减少区域位于非典型位置，这引发了关于哪些脑区可导致明确精神综合征的疑问。
