Abstract	A patient with crossed Broca's aphasia, caused by brain hemorrhage, exhibited peculiar optic echographia. The patient was a 52-year-old right-handed male with no familial background of sinistrality. CT-scans revealed a right putaminal hemorrhage. ¹²³I-IMP-SPECT demonstrated a low blood flow area in the right frontal and temporal lobes. No obvious low blood flow area was seen in the left hemisphere. Pick first reported echographia in 1900. Echographia was classified into optic and auditory types, according to whether the stimuli were optic (visual characters) or auditory (spoken sounds). The patient exhibited optic echographia up to six months after the onset. Auditory echographia and echolalia were not observed. The optic echographia took the following course: complete and mitigated echographia (stage1), mitigated echographia (stage2), gradual dissappearance of the echographia. We considered that the following factors could play important roles in causing echographia in this case: 1) general mental state in the subacute stage (Durchgangs-syndrome; Wieck, 1967), 2) disinhibition of writing may be due to the damage to the right hemisphere, 3) Witzelsucht and the disinhibitory behavior could be caused by the frontal lobe dysfunction, and 4) organic psychiatric symptoms may be present, including general apathy, unawareness of or inattention to his own deficits, etc.
