作者报告2例颅骨恶性淋巴瘤,肿瘤内容CT表现为软组织成份。例2肿瘤位于骨板两侧。例1肿瘤部位的颅骨内板轻度不规则。骨恶性淋巴瘤经常呈浸润性生长,软组织肿块大而骨皮质破坏轻。例2经髓腔通过硬脑膜的穿通血管和神经进入蛛网膜下腔扩散。例1肿瘤内面光滑,无神经症状,是肿瘤未穿过硬脑膜生长的证据。作者指出,尤文氏瘤、成骨肉瘤、骨髓炎和骨转移癌与原发骨淋巴瘤鉴别困难,尤其是尤文氏瘤发生在颅骨时。因为尤文氏瘤比骨淋巴瘤更好发于扁骨。然而尤文氏瘤发 The authors reported two cases of malignant lymphoma of the skull. The CT content of the tumor showed soft tissue components. Case 2 tumors are located on both sides of the plate. Example 1 Skull inner plate of the tumor site was slightly irregular. Bone malignancies often show invasive growth, with large soft tissue masses and less cortical bone destruction. Example 2 Through the medullary cavity through the dura through the blood vessels and nerves into the subarachnoid space diffusion. Example 1 The tumor had a smooth inner surface and no neurological symptoms. It was evidence that the tumor did not pass through the dura mater. The authors pointed out that Ewing’s tumor, osteosarcoma, osteomyelitis, and metastatic bone cancer are difficult to distinguish from primary bone lymphoma, especially when the Ewing’s tumor occurs in the skull. Because Ewing’s tumor is better than bone lymphoma in the flat bone. However, Ewing’s tumor
