TCS images of mesencephalic (a, b, c, d) and diencephalic plane (e). a Normal echogenicity of BR (thin arrow), grade 2; thick arrow indicates hyperechogenicity of LN. b Pathologic echogenicity of BR, the echogenic line of the raphe appears abnormally slight and thin, grade 1. c Pathologic echogenicity of BR, the raphe is not visible, grade 0. d Normal echogenic area of SN. e Hyperechogenicity of CN (thin arrow), width of the frontal horn of the lateral ventricle (2) and of the third ventricle (1)
