The nurse is aware of which of the following with respect to a patient diagnosed with a brain angioma?
A) Brain angiomas infrequently originate in the cerebellum.
B) The patient is at an increased risk for stroke.
C) All angiomas cause symptoms.
D) Brain angiomas are not highly vascular.
Ans: B
Feedback: Brain angiomas (masses composed largely of abnormal blood vessels) are found either in or on the surface of the brain. They occur in the cerebellum in 83% of cases. Some persist throughout life without causing symptoms; others cause symptoms of brain tumor. The diagnosis maybe suggested by the presence of another angioma somewhere in the head or by a bruit (an abnormal sound) audible over the skull. Because the walls of the blood vessels in angiomas are thin, brain angioma patients are at risk for a cerebrovascular accident (CVA). In fact, cerebral hemorrhage in people younger than 40 years of age suggests the possibility of an angioma.
