The purpose of this study is to evaluate the ultrasonographic internal architecture of cervical mass lesions with the modified complexity value (MCV), and to determine whether the MCV is a valid diagnostic parameter in the differentiation between malignant and benign mass lesions. The fifty enlarged cervical mass lesions (malignant tumor; 27, benign lesion including cyst; 23) were examined with a linear ultrasound scanner. Two hundred fifty six gray scale images were reconstructed in the 16 gray scale ones. Definite diagnosis of the nodes was obtained by histological examination following cervical mass enucleation. The sum of MCV values of the malignant mass lesions was higher than that of the benign ones.The MCV of cervical mass ultrasonogram is an useful parameter for differentiation between malignant and benign enlargement in the cervical mass lesions.
