Spondylodiscitis is an infection of the intervertebral disc, the adjacent vertebral body, and/or contiguous structures due to the introduction of infectious agent, usually by the hematogenous route. Imaging is crucial in assessing bacterial and tubercular spondylodiscitis, as well as their associated complications. Magnetic resonance imaging in particular can clearly depict osteo-structural changes in the vertebral body and the associated disc, as well as any soft-tissue complications, such as paravertebral abscess and/or epidural abscess, improving disease characterization and helping to recognize the agent involved. Nevertheless, other non-infectious diseases may mimic imaging appearances of spondylodiscitis and one should be aware of these conditions when interpreting MR images, which include Modic type I degenerative changes, ankylosing spondylitis, acute Schmorl's node, porotic fractures, and spinal neuropathy arthropathy. This pictorial review aims at describing imaging findings of bacterial and non-bacterial spondylodiscitis, complications, and those pathologies that mimic these infections.
脊柱椎间盘炎是由于感染因子的侵入，通常通过血行途径，导致椎间盘、相邻椎体和/或连续结构的感染。影像学检查对于评估细菌性和结核性脊柱椎间盘炎及其相关并发症至关重要。特别是磁共振成像能够清晰地描绘椎体和相关椎间盘的骨结构变化，以及任何软组织并发症，如椎旁脓肿和/或硬膜外脓肿，有助于疾病的特征性诊断并识别所涉及的病原体。然而，其他非感染性疾病可能会模仿脊柱椎间盘炎的影像学表现，在解读磁共振图像时应了解这些情况，其中包括Modic I型退变、强直性脊柱炎、急性Schmorl结节、骨质疏松性骨折和脊髓神经病性关节病。本图谱综述旨在描述细菌性和非细菌性脊柱椎间盘炎的影像学表现、并发症以及那些模仿这些感染的病理情况。
