Patient: Hemangioma, no MRI examination, then two courses of superficial X-ray irradiation, during which the mass shrank a little, but now it has grown again, with a diameter of 2 cm, the mass will swell when the weather is too hot or when the child cries, the child is now developing normally, can walk alone, can run, can speak simple words, vision is also normal. Is it very likely that the child has meningeal bulge, and if so, does it have to be treated surgically? Can the MRI examination and CT results confirm the diagnosis of the disease? And what is the approximate cost of surgery for meningeal bulge? Expert: The diagnosis of meningeal bulge can be made clearly by MRI and CT examination. Currently, local radiation therapy is not recommended even for children with hemangioma, because it is recognized that radiation therapy may cause local skin deformation and later malignant changes may occur. The cost of surgery for meningeal bulge varies from place to place and depends on the size of the defect and whether patching materials are needed, which is about 20,000 RMB in Shanghai.
