title: [Subarachnoid hemorrhage from cerebral artery aneurysm within the context of a fall: external or internal etiology?].
abstract: A neurosurgical expertise had to be performed to answer the following question: Was a subarachnoid hemorrhage from a cerebral aneurysm the cause or the result of the fall of a 60 year old man? And with which degree of certainty can this question be answered? It is argued that any statements in this respect cannot but have the degree of a "possibility" (i.e. nearly 30% of the truth). From a medlineR-research data to estimate the prevalence of cerebral aneurysms (1% of all inhabitants) and the incidence of subarachnoid hemorrhage (10/100,000/yr.) became available (assuming a mean life expectancy of 75 years). It is argued that presumably every fourth cerebral aneurysm does not rupture during lifetime. Insofar there is a "scientifically based possibility" that the case under discussion suffered from a subarachnoid hemorrhage resulting from a fall from height as an outer cause of a significant deterioration of a hitherto silent inborn disease.
