目的:提高对儿童白血病侵犯颅骨的X线和CT表现的认识。材料和方法:回顾性分析2例经骨髓细胞学检查证实为白血病的颅骨X线和CT表现。结果:2例中1例X线片表现为颅骨多发不规则低密度灶,边缘欠清晰,周围无明显硬化,同时伴双侧髂棘下、股骨大转子多发小囊状骨质吸收,边缘欠清,骨皮质无中断;另1例颅脑CT平扫颅窗显示脑实质未见明显异常,骨窗显示枕骨内外板增厚、局部骨质破坏、并见高密度坏死骨。2例均为L2型急性淋巴细胞白血病(ALL-L2)。结论:儿童白血病侵犯颅骨的X线、CT表现具有多样性,结合骨髓细胞形态学检查可以做到早期诊断。
Objective: To improve the understanding of X-ray and CT findings of childhood leukemia invade skull. Materials and Methods: A retrospective analysis of 2 cases of bone marrow cytology confirmed leukemia skull X-ray and CT findings. Results: In 2 cases, X-ray showed irregular multiple low-density craniofacial lesions. The edges were not clear, and there was no obvious sclerosis around them. At the same time, there were bilateral small iliac spines, multiple small trochanteric femoral bone absorption, Clear, cortical bone without interruption; the other 1 case of craniocerebral CT scan cranial window showed no obvious parenchymal brain abnormalities, bone window shows the occipital bone plate thickening, local bone destruction, and see the high-density necrosis of the bone. Both cases were type-2 acute lymphoblastic leukemia (ALL-L2). CONCLUSION: X-ray of children with leukemia invades the skull, CT showed a diversity, combined with bone marrow cell morphological examination can be done early diagnosis.
