AIM: The purpose of the present study was to investigate the regional cerebral blood flow (rCBF) of patients with delusional disorder, somatic type (DDST) exhibiting somatic hallucination.
METHODS: Five patients diagnosed with DDST, as well as 20 control subjects, were examined. All subjects underwent technetium-99m ethyl cysteinate dimer brain perfusion single-photon emission computed tomography. Statistical analysis was performed with SPM5, using a two-sample t-test model to test the regional population effect on rCBF.
RESULTS: Patients with DDST had a significant increase in perfusion in the left post-central gyrus and the right paracentral lobule, both of which are involved in somatic sensory processing.
CONCLUSION: Somatic hallucination might be associated with increased perfusion in the primary somatosensory regions.
