Tumor thrombosis of the internal jugular vein (IJV) represents an uncommon event, usually in the setting of underlying thyroid neoplasms. Extraosseous plasmacytoma (EMP) with tumor thrombosis of the IJV has not yet been reported in the literature. We present a unique case of a plasmacytoma in the left parapharyngeal space with direct extension to the left IJV, documented with contrast enhanced computed tomography and US Doppler. Presence of avid thrombus enhancement allowed differentiation between tumoral extension and thrombothic changes.
颈内静脉肿瘤血栓形成是一种罕见事件，通常发生在存在潜在甲状腺肿瘤的情况下。文献中尚未报道过伴有颈内静脉肿瘤血栓形成的骨外浆细胞瘤（EMP）。我们报告了一例独特的病例，左侧咽旁间隙浆细胞瘤直接蔓延至左侧颈内静脉，通过增强CT和超声多普勒得以记录。强化血栓的存在有助于区分肿瘤蔓延和血栓形成改变。
