CAPGRAS SYNDROME ASSOCIATED WITH A FRONTAL-LOBE TUMOR

We report a case of the Capgras Syndrome in a 67 year old woman who was found to have a glioma of the left frontal lobe. Our case illustrates the multiplicity of possible aetiological factors which frequently coexist in this condition and make any assessment of possible pathogenetic mechanisms difficult. However, there appears to be a consensus of recent neuro-imaging studies that frontal lobe pathology may be important. The possible relevance of this is discussed together with a suggestion for further elucidation of the origin of the delusion.
