A 46 y/o woman who is a school bus driver by occupation presents to your office for regular follow up. She has a history of ADPKD. Her blood pressure is well controlled at 120/70 on enalapril. She has no other problems. She denies any headache. There is no family history of intracranial or subarachnoid hemorrhage. However, she is concerned that her head might explode because her sister who also has ADPKD was recently diagnosed of having a berry aneurysm. She wants to be screened for berry aneurysm as soon as possible. Her physical examination is benign and does not reveal any focal neurological deficits. Which of the following suggests the necessity for screening in her case?
A. Family history of berry aneurysm
B. Polycystic kidneys
C. School bus driving
D. Cysts in the liver
E. No screening necessary in her case

Answer. C
High risk jobs ( pilot, bus driver etc) is one of the indications to screen for berry aneurysm in asymptomatic ADPKD patients. Family hx of berry aneurysm (Ans. A) alone does not warrant screening for berry aneurysm in asymptomatic ADPKD patients. Asymptomatic ADPKD patients must be screened if there is a family history of “Ruptured” berry aneurysm ( history of SAH in the family etc)
E. is not the answer because this patient is a school bus driver by occupation and needs to be screened.
Key Concepts ( from dr.red nephrology lectures) :
Screening for Berry Aneurysms:
- MRA of head – recommended screening test to detect berry aneurysms.
- Screen only if
- family history of subarachnoid hemorrhage ( Family hx of a ruptured berry aneurysm) not just a family history of berry aneurysm.
- Patients with with high risk jobs (pilots/ bus-drivers) - an event during such a job is a risk to other’s safety as well.
- Patients with symptoms suggestive of a berry aneurysm
( severe headache, focal neurological deficits)
