ANSWERS AND EXPLANATIONS




A) Berry aneurysms are multiple in 90% of cases

This answer is correct.


Berry aneurysms are not TRULY congenital and are found in up to 2% of autotopsy series (in previously healthy people). The aneurysm is multiple in 20% of patients. The aneurysms are mainly located at the major side-branches at the circle of Willis. Adult polycystic kidneys disease and aortic coarctation are associated with intracranial Berry aneurysm; examine for these in all cases of SAH. "Mycotic" aneurysms in bacterial endocarditis are mainly found in the distal portions of middle cerebral arteries; these are responsible for 2-3% of ruptures.   (See References)
