Physical exainination revealed impaired consciousness and dementia appearance. The head computed tomography （CT） showed a suprasellar lesion of mixed densities without bone invasion, as well as the eggshell calcification presented as interrupted little patches of high-density encircling focus [Figure 1a].展开更多
