Magnetic resonance imaging findings were compared in 22 familial and 29 sporadic cases with DSM-III-R diagnoses of schizophrenia, schizoaffective, or schizophreniform disorders. Volumetric measurements were used to assess the size of brain structures, including the cranium, cerebrum, lateral ventricles, temporal horns, third ventricle, lenticular nuclei, amygdaloid-hippocampal complex, and cerebellum, as well as the asymmetry of the lateral ventricles. Increased volume of the lenticular nuclei and greater ventricular asymmetry (the left ventricle being larger) were found in familial cases compared with sporadic cases and normal control subjects. It is possible that increased lenticular nuclei volume and greater lateral ventricular asymmetry reflect the role of genetic factors in schizophrenia.
