[Localization of aphasic symptoms: preliminary observations with C.T. scanner (author's transl)].

Twenty patients with aphasia and left-hemisphere damage were examined with a standard language battery, and Computerized Axial Tomography. Patients were divided into fluent (N = 9) and nonfluent (N = 6) on the basis of the language examination; 5 patients who could not be classified in either category were excluded. Lesions were retrorolandic in 8 out of 9 fluent aphasics while extending anteriorly in all 6 nonfluent aphasics. Some unexpected lesions were also found. Five cases -- 3 fluent and 2 nonfluent -- are discussed in detail.
