Plasmacytoma is a malignant plasma cell tumor growing within soft tissue or the axial skeleton. Here, we present the case of a patient with plasmacytoma of the axis vertebra who underwent decompressive surgery with reconstruction via a posterior approach. The patient was referred because of quadriparesis with severe neck pain. Magnetic resonance imaging revealed a relatively demarcated, highly enhanced mass lesion in a destructed axis, with spinal cord compression. Computed tomography revealed a 5.6×4.3 cm adrenal mass at the left retroperitoneal space. We suspected the axis lesion to be a metastatic paraganglioma from the adrenal mass. The patient underwent total excision of the tumor under an operative microscope with occipitocervical fixation. Histopathologically, the tumor was shown to be a plasmacytoma. Following the operation, the patient recovered without significant complications. This was a rare case of plasmacytoma in the axis, mimicking metastatic paraganglioma.
浆细胞瘤是一种生长于软组织或中轴骨骼的恶性浆细胞肿瘤。在此，我们报告一例枢椎浆细胞瘤患者，该患者接受了后路减压手术并进行了重建。患者因四肢瘫伴严重颈部疼痛前来就诊。磁共振成像显示在破坏的枢椎中有一个边界相对清晰、高度强化的肿块病变，伴有脊髓受压。计算机断层扫描显示左腹膜后间隙有一个5.6×4.3 cm的肾上腺肿块。我们怀疑枢椎病变是肾上腺肿块转移而来的副神经节瘤。患者在手术显微镜下接受了肿瘤全切并进行了枕颈固定。组织病理学检查显示肿瘤为浆细胞瘤。术后患者恢复良好，无明显并发症。这是一例罕见的枢椎浆细胞瘤病例，误诊为转移性副神经节瘤。
