[An autopsy case of transcortical motor aphasia].

[Article in Japanese]


An autopsy case of transcortical motor aphasia is presented with a pathology located anterior and superior to the pars opercularis of the left inferior frontal gyrus. Case H. Y. A 60-year-old right-handed man. On Nov. 14, 1978, the patient had surgery to remove cerebral hematoma in the left frontal lobe. In the neuropsychological examination before the operation, he had shown the clinical features of transcortical motor aphasia characterized by good comprehension of language, preserved repetition, and spontaneous speech disorder. In this stage, it was supposed that the underlying disturbance of spontaneous speech was due to the disabilities of contextual constructions of sentences rather than the lack of speech initiation. Following the operation, however, spontaneous speech disappeared completely for several days. At the same time, the patient showed problems in comprehension, reading, writing and confrontation naming as well as symptoms of disorientation, pathological inertia and 'loss of initiation' in the psychomotor domain. During the following three months, however, the patient did show slight improvement, except for contextual sentence constructions and pathological inertia when taking the complex animal drawing test. In his terminal stages, the clinical symptoms could be summarized as transcortical motor aphasia and mild frontal lobe syndrome. On March 1, 1979, the patient died of Hamman-Rich syndrome. Postmortem examination: The brain weighed 1294 gm. The external observation of the brain disclosed the linear tissue defect, about 15 mm in length and 10 mm in width, along the radial sulcus of the pars triangularis of the left inferior frontal gyrus.(ABSTRACT TRUNCATED AT 250 WORDS)
