An out‐of‐body experience (OBE) is a phenomenon whereby an individual views his/her body and the world from a location outside the physical body. Previous studies have suggested that the temporoparietal junction (TPJ), the brain region responsible for integrating multisensory signals, is responsible for OBE development. Here, however, we first present a case of OBE after brain tumour development in the posterior cingulate cortex (PCC). The patient was a 46‐year‐old right‐handed female; she underwent brain surgery. She reported that she had experienced OBEs several times monthly (during daily life) before surgery but never after surgery. She defined her OBEs explicitly; she drew pictures. Her OBEs exhibited phenomenological, overt dissociation of the subjective and objective bodies. We discuss the mechanisms underlying this phenomenon and the relationship between OBEs and the PCC in terms of anatomical and functional brain connectivity. Our case sheds some light on the mechanism involved in creating spatial (dis)unity between the self and the body.

主观和客观身体的分离：后扣带回病变发展后的体外体验。

体外体验（OBE）是一种现象，人们可以从身体外部的某个位置观看他/她的身体和世界。先前的研究表明，颞顶交界处（TPJ）是负责整合多感觉信号的大脑区域，它负责OBE的发育。但是，在这里，我们首先介绍了在后扣带回皮质（PCC）中发生脑肿瘤后的OBE病例。该患者是一名46岁的右撇子女性；她接受了脑部手术。她报告说，她在手术前每月（在日常生活中）经历过几次OBE，但从未经历过手术。她明确定义了OBE；她画了照片。她的OBE表现出主观和客观身体的现象学，明显的分离。我们从解剖学和功能性大脑连通性的角度讨论了这一现象的潜在机制以及OBE与PCC之间的关系。我们的案例揭示了在自我与身体之间造成空间（不和谐）的机制。
