Spinal epidural lymphoma is rarely found in Japan, comparing with Europe and America. We experienced two cases, who were suffered from intractable pain and gait disturbance. In both cases, a wide laminectomy and partial removal of the epidural tumor were performed because of the deteriorated paraparesis. After that, they were able to walk without support. These epidural tumors were supposed to be primary spinal epidural lymphomas, judging from the clinical course and some other examinations, that is, Gallium scintigram and CT scan, etc. There were few reports that mentioned CT findings of spinal lymphomas. In our two cases, we got the characteristic CT findings of spinal lymphomas. In case 1, plain CT demonstrated a high density mass at epidural space extending into the intra- and extra-foraminal region. CT scan following intravenous injection showed the tumor enhancement remarkably and homogeneously. Bone erosion was not found even on plain CT, in both cases. These findings were thought to be different from those of metastatic tumors. It may be possible to diagnose and decide the therapeutic planning preoperatively, when we get these characteristic CT findings of spinal lymphomas.
与欧美相比，脊髓硬膜外淋巴瘤在日本很少见。我们遇到了两例患有顽固性疼痛和步态障碍的患者。在这两例中，由于截瘫加重，均进行了广泛的椎板切除术和硬膜外肿瘤部分切除术。此后，他们能够在无需支撑的情况下行走。根据临床病程以及镓闪烁扫描和CT扫描等其他检查判断，这些硬膜外肿瘤被认为是原发性脊髓硬膜外淋巴瘤。很少有报告提及脊髓淋巴瘤的CT表现。在我们的两例病例中，我们获得了脊髓淋巴瘤的特征性CT表现。在病例1中，平扫CT显示硬膜外间隙有高密度肿块，延伸至椎间孔内和孔外区域。静脉注射后CT扫描显示肿瘤明显且均匀强化。在两例病例的平扫CT上均未发现骨质侵蚀。这些表现被认为与转移瘤不同。当我们获得这些脊髓淋巴瘤的特征性CT表现时，有可能在术前进行诊断并制定治疗方案。
