We report five patients in whom spinal MRI revealed extra-arachnoid fluid collections. These spinal fluid collections most likely resulted from accumulation of cerebrospinal fluid (CSF) from a dural leak. The patients presented with either compressive myelopathy due to the cyst or superficial siderosis (SS). All of these fluid collections were long segment, and MRI demonstrated the fluid collections but not the exact site of leak. Dynamic CT myelogram demonstrated the site of leak and helped in the management of these complicated cases. Moreover, we also found that the epicenter of the fluid collection on MRI was different from the location of the leak on a dynamic CT myelogram. Knowledge of these associations can be helpful when selecting the imaging studies to facilitate diagnosis and treatment.
我们报告了5例患者，其脊柱MRI显示蛛网膜外积液。这些脊柱积液很可能是由于硬脑膜漏导致脑脊液（CSF）积聚所致。患者表现为囊肿引起的压迫性脊髓病或浅表性铁沉积症（SS）。所有这些积液均为长节段，MRI显示了积液，但未显示漏液的确切部位。动态CT脊髓造影显示了漏液部位，并有助于这些复杂病例的处理。此外，我们还发现MRI上积液的中心与动态CT脊髓造影上漏液的位置不同。了解这些关联在选择影像学检查以促进诊断和治疗时可能会有所帮助。
