- Abstract:
- Objective To explore the features and value of ultrasonography in diagnosing skull lesions of Langerhans cell histiocytosis in children.Methods The ultrasonographic findings of 19 cases of skull lesions of Langerhans cell histiocytosis were analyzed retrospectively.The ultrasonographic features were summarized and compared with the findings of computed tomography (CT) and magnetic resonance imaging (MRI).Results Twenty-five lesions in 19 cases were revealed by ultrasound.Four cases had multiple lesions.The sites were temporal (n=12),parietal (n=7),occipital (n=5) and buccal (n=1); Ultrasound revealed skull lesions involving inner and outer tables with sharp edge and irregular shape.The edge was ladder-like.Bone pieces could be visualized in 3 lesions.All lesions were accompanied by hypoechoic soft tissue mass and two had an echoless zone.Abundant blood flow signal could be visualized in masses; CT & MRI:19 cases underwent CT examination while 4 cases received MRI examination.Skull lesions were detected with soft tissue masses.One horacic lesion was detected by CT.Conclusion The skull lesions of Langerhans cell histiocytosis had characteristic ultrasonographic features.Ultrasonography may be helpful and preferred for initial evaluations of suspected skull lesions of Langerhans cell histiocytosis as it is non-invasive,radiation-free and inexpensive.
