True solitary plasmacytoma of the skull without signs of systemic myelomatosis is very rare as is orbital involvement. It can be part of generalized disease (multiple myeloma) or localized disease, presenting as orbital tumor. We describe a case of solitary osseous plasmacytoma of the orbit. This 40-year-old man presented with a four month history of proptosis of the left eye, swelling in the left orbito-temporal region with a mild decrease in visual acuity. Multidetector row computed tomography scan showed a geographic osteolytic, well-demarcated lesion involving the greater wing of the sphenoid bone showing homogeneous contrast enhancement with extra-axial extension to the middle and anterior cranial fossa extension with extraconal extension into the orbit at the right side. Fine needle and later biopsy of the lesion revealed plasmacytoma.
无系统性骨髓瘤迹象的真性孤立性颅骨浆细胞瘤非常罕见，眼眶受累情况亦如此。它可以是全身性疾病（多发性骨髓瘤）的一部分，也可以是局限性疾病，表现为眼眶肿瘤。我们描述了一例眼眶孤立性骨浆细胞瘤病例。该40岁男性有4个月左眼突出病史，左眶颞部肿胀，视力轻度下降。多排探测器计算机断层扫描显示一个边界清晰的地图样骨质溶解病变，累及蝶骨大翼，呈均匀强化，向轴外延伸至中颅窝和前颅窝，锥体外延伸至右侧眼眶。对该病变进行细针穿刺活检及后续活检显示为浆细胞瘤。
