房间倾斜错觉（RTI）是一种环境视觉空间感知的短暂性障碍，由视觉场景的阵发性倾斜组成。这是由于视觉和前庭三维坐标图的错误皮质错配。本回顾性病例系列包括13名受试者。7例患者临床表现为视场沿冠状面旋转180A(0)。在我们的研究中，RTI最常见的原因是后循环缺血（5例）。内淋巴囊肿瘤、重症神经病、急性外伤性脊髓病和多系统萎缩引起RTI的病例尚属首次报道。未发现幕上局灶性病变。为了描述RTI的临床和影像学特征，我们回顾了文献中报道的135例RTI病例。男性占优势（60.2%）。平均年龄51.2±20.3岁。最常见的损伤部位是中枢神经系统（CNS）（61.4%）。幕上和幕下结构占相同的病变频率。最常见的病因是脑缺血（梗死或短暂性缺血发作；27.7%）。与非血管性疾病患者相比，这些患者明显年龄较大，其病变通常累及后窝结构。综上所述，RTI是几种中枢神经系统和前庭神经系统疾病的表现，很少是周围神经系统疾病的表现，由前庭和感觉知觉或整合的破坏引发。脑缺血性疾病是这种罕见综合征最常见的病因。
Room tilt illusion (RTI) is a transient disorder of the environmental visuo-spatial perception consisting of paroxysmal tilts of the visual scene. It is attributed to an erroneous cortical mismatch of the visual and vestibular three-dimensional coordinate maps. Thirteen subjects were included in this retrospective case series. Clinical presentation was 180A(0) rotation of the visual scene following the coronal plane in seven patients. The most common cause for RTI in our series was posterior circulation ischaemia (five cases). Cases of endolymphatic sac tumour, critical illness neuropathy, acute traumatic myelopathy and multiple system atrophy causing RTI are reported for the first time. No case of supratentorial focal lesion was found. In order to describe the clinical and imaging features of RTI, 135 cases previously reported in the literature were reviewed along with our series. There was a male predominance (60.2 %). Mean age was 51.2 +/- A 20.3 years. The most common location of the injury was the central nervous system (CNS) (61.4 %). Supratentorial and infratentorial structures accounted for the same frequency of lesions. The most common aetiology was cerebral ischaemia (infarction or transient ischaemic episode; 27.7 %). These patients were significantly older and their lesions commonly involved posterior fossa structures when compared to patients with non-vascular disorders. In summary, RTI is a manifestation of several CNS and vestibular disorders, and rarely of peripheral nervous system disorders, triggered by disruption of vestibular and sensory perception or integration. Cerebral ischaemic disorders are the most common aetiology for this rare syndrome.
