INTRODUCTION: In schizophrenia patients the lateral ventricle enlargement has mostly been reported in relationship with smaller cortical and/or subcortical brain volumes; and it has been observed that ventricular system growth may be a consequence of the smaller caudate nucleus volume. Bicaudate parameters have been used in the Alzheimer dementia and Huntington's chorea diagnosing in order to evaluate brain changes and the enlargement of the lateral ventricles. SUBJECTS AND METHODS: This study has been carried out on 140 patients out of which 70 patients (30 men and 40 women) who met the ICD 10 criteria for schizophrenia and 70 healthy controls (30 men and 40 women) matched on sex and age with the studied group. All of them underwent direct caudatometry and volume computation based on MRI scans. RESULTS: Except for the bicorporal line, for all the parameters were obtained the statistically highly significant differences between the examined and control groups. Significant correlation was established for the majority of bicaudate parameters and volumes of the caudate nuclei and lateral ventricles. DISCUSSION: Enlargement of the lateral ventricles is one of the most frequent MRI finding in schizophrenia patients. Ventricles are enlarging gradually and frontal horns are more affected than other parts. The increased volumes of the caudate nuclei signalized that ventricular enlargement is not the consequence of the caudate atrophy. CONCLUSION: Bicaudate parameters are reliable parameters for the quick orientation in order to assess the enlarged ventricles in schizophrenia patients.
