BERRY ANEURYSM

A different type of aneurysm can occur at the base of
the brain. The arteries at this site may have a developmental
defect and form small berry-like aneurysms that
may remain asymptomatic until a rupture occurs when
the individual is between 20 and 50 years old. A subarachnoid
hemorrhage at the base of the brain may damage
the brain substance and cause coma, death, or severe
disability.
These aneurysms may cause sudden intense headaches.
Berry aneurysms are not related to high blood pressure,
but coexisting hypertension may predispose them to
rupture. Patients with coarctation of the aorta or polycystic
kidney disease may have coexisting berry aneurysms, and
these individuals and family members should be screened
with MRI. Fortunately, these aneurysms can be surgically
clipped off prior to their rupture. A beta-blocking drug
is useful during the perioperative period.
