Question

Which of the following statements about berry aneurysms in the brain is not true?

	A.	following rupture there is sudden onset headache
	B.	they usually develop at points of bifurcation in the circle of Willis
	C.	they are usually asymptomatic for many years
	D.	following rupture, blood appears in the subarachnoid space
	E.	when rupture they cause intracerebral haematoma

Answer 1

A berry aneurysm or saccular aneurysm usually occurs at the base of the brain in the circle of Willis. Ruptured aneurysm bleeds into the subarachnoid space, leading to subarachnoid hemorrhage. Early symptoms of rupture are severe headache, eye pain, vision deficits, etc. A berry aneurysm may be asymptomatic for many years. It will never bleed into the brain tissue and hence will not lead to intracerebral hemorrhage.

Hence, the false statement is option (E) when ruptured they cause intracerebral haematoma.
