<br/><br/> OBJECTIVES: To describe the design and rationale of a new system of classifying and grading intracranial lesions.<br/><br/>METHODS: Intracranial lesions were organized into disease groups. The most relevant characteristics that best describe the lesion in each disease group were selected and defined. The characteristics were dichotomized and given numerical scores which were added to obtain the lesion grade. Pairs of defined characteristics were utilized to designate to which class and subclass each lesion would belong.<br/><br/>RESULTS: An illustrative use in classifying and grading brain tumors was presented. The system facilitated the selection and evaluation of different treatment methods.<br/><br/>CONCLUSION: Intracranial lesions were both classified and graded using a new system which utilized pairs of relevant characteristics dichotomized into opposite attributes and used to designate the class and also scored to obtain the lesion grade.
