Eosinophilic granuloma (EG) is a well-recognised benign form of Langerhans-cell histiocytosis. The estimated incidence of EG is 3-4 per million of the population. More patients are children and adolescents between the ages of 1 and 15 years. The value of plain films in the diagnosis of the EG is limited and the extent of the disease is better defined by multidetector CT (MDCT) scanning. MDCT scan with multiplanar and three-dimensional reconstruction image of the skull and brain clearly demonstrates bone destruction and soft-tissue involvement of the tumour. In this article we present the MDCT imaging characteristics of EG of the skull and discuss the differential diagnosis of this rare lesion with reference to recent literatures.
嗜酸性肉芽肿(EG)是朗格汉斯细胞组织细胞增多症一种公认的良性形式。EG的估计发病率为每百万人口3 - 4例。更多患者是1至15岁的儿童和青少年。平片在EG诊断中的价值有限,而多排螺旋CT(MDCT)扫描能更好地明确疾病范围。MDCT对头骨和脑部进行多平面及三维重建成像,可清晰显示肿瘤的骨质破坏和软组织受累情况。在本文中,我们展示了颅骨EG的MDCT成像特征,并参考近期文献讨论了这种罕见病变的鉴别诊断。
