A system has been programmed to allow model self-structuring to account for observations including both pathological evidence and symptomatological findings. The model modifies its structure in response to supplementary observations. The physiopathological mechanisms formalised by the model can be used for diagnostic purposes. Unknown diseases are diagnosed by direct inference of the relevant physiopathological mechanisms of the model or, if required, by automatic modification of the model that accounts for them.
Four cases of arteriosclerotic aneurysm of the arteria lusoria are described. In one patient a tumor of the superior mediastinum was suspected, the chief signs of which are dyspnea and irritative cough. In a further patient, enlargement of the left superior mediastinum was noted in routine fluoroscopy. Clinical investigation revealed an aneurysm of the arteria lusoria. In the third patient, dysphagia, slight cough and torticollis were interpreted as symptoms of a neoplasm of the esophagus or larynx. The fourth patient, in whom aneurysm of the arteria lusoria was discovered by chance at autopsy, displayed no clinical or radiological signs. Abberrant right subclavian artery (arteria lusoria) is a relatively frequent finding in autopsies. Aneurysm of the arteria lusori is apparently also a typical complication.
