DrVirgo Forum Hero Topics: 1096 Posts: 3,515	04/27/06 - 09:13 AM             #1 CLICK TO ENLARGE. 48. The vertebral angiogram shown is from a 40-year-old man. The abnormality is marked by "X." Which of the following clinical findings is most likely to be present? A) Aphasia B) Ataxic limb movements C) Resting tremor D) Spastic hemiparesis E) Visual field defect Attached Files: angiogram.JPG (11 KB, 368 downloads) ___________________ Our greatest glory is not in never falling, but in rising every time we fall.

robin082006 Forum Hero Topics: 471 Posts: 5,123	04/27/06 - 09:43 AM             #3 I think it is a branch of anterior cerebral artery (e.g. anterior communicating), This may be aneurism of anterior communicating artery. ruture causes subarachnoid hemorrhage may be E? ___________________ The Key to Succeed is Patience.

robin082006 Forum Hero Topics: 471 Posts: 5,123	04/27/06 - 12:16 PM             #5 There is a similar picture in Kaplan Anatomy note. The "bigger " is Anterior CA, and the smaller is Middle Cerebral Artery. Not sure, please review and give your idea. ___________________ The Key to Succeed is Patience.
DrVirgo Forum Hero Topics: 1096 Posts: 3,515	04/27/06 - 12:19 PM             #6 Isnt MCA generally bigger than ACA? I'm not sure either. I can't orient myself on this picture. ___________________ Our greatest glory is not in never falling, but in rising every time we fall.
robin082006 Forum Hero Topics: 471 Posts: 5,123	04/27/06 - 12:33 PM             #7 Anyone please explain! But anyways answer should be A (branch of Middle CA) or E (branch of Anterior CA) ___________________ The Key to Succeed is Patience.
DrVirgo Forum Hero Topics: 1096 Posts: 3,515	04/27/06 - 05:00 PM             #8 I have no idea. If anyone can explain, that would be great! ___________________ Our greatest glory is not in never falling, but in rising every time we fall.
DrVirgo Forum Hero Topics: 1096 Posts: 3,515	05/02/06 - 11:41 AM             #9 Which artery is shown in the right top side of the picture? which artery is labeled with the X? ___________________ Our greatest glory is not in never falling, but in rising every time we fall.
raddoc Forum Newbie Topics: 5 Posts: 19	05/02/06 - 11:59 AM             #10 I think the anurysm is on a branch of the basilar artery (probably superior cerebellar A) since this is a vertebral angiogram and ataxic movements might be the answer.
r_albayunen Forum Senior Topics: 0 Posts: 218	05/02/06 - 04:23 PM             #11 i think its a branch to the cerebellum ... ill go with ataxic problems as well as raddoc.
krsna Forum Senior Topics: 1 Posts: 211	05/15/06 - 09:20 AM             #12 i think its the ant inf cerebellar artery....anyways B would be my option.. correct me if wrong
Harry Potter Forum Junior Topics: 1 Posts: 46	05/22/06 - 04:30 AM             #13 Krsna is correct. It is AICA AV malformation; so the answer is B- ataxia The major vessels seen for below up are 1. PICA arisign from vertebral 2. AICA- from basilar 3. Supperior cerbellar from basilar 4. PCA from Basilar
ankman81 Forum Newbie Topics: 0 Posts: 1	05/22/06 - 12:40 PM             #14 the question root says this is a verterbral arteriogram.. the link you posted is for ICA. branches of vertebral = Pica, AICA. harry potters got it right
waqastariq	06/04/06 - 12:59 PM             #15 I think this is a part of anterior inferior cerebellar artery and this is vertebral angiogram... so B is the answer with Ataxic gait thanks
nadiabarati	06/06/06 - 05:58 PM             #16 yes AICA and B is the answer
rman Forum Senior Topics: 39 Posts: 123	06/14/06 - 02:25 PM             #17 Guys, this aint the AICA. It's a vertebral angiogram and some vessel leaving off the vertebral looks to have some sort of lesion, looks like some sort of AV malformation. The most important branch off the vetebral is the PICA which produces a lateral medullary syndrome, part of which is ataxia.
waqastariq	06/15/06 - 11:41 AM             #18 B
Dr.Papez Forum Senior Topics: 0 Posts: 152	06/16/06 - 10:09 AM             #19 AVM that is seen is from a brach from Basilar. The artery below is the PICA. look again.
Dr.Papez Forum Senior Topics: 0 Posts: 152	06/16/06 - 10:11 AM             #20 it is AICA...AICA....AICA only
docarchana Forum Guru Topics: 70 Posts: 515	09/10/06 - 07:03 PM             #21 so B is the right ans.

IceAge Forum Senior Topics: 21 Posts: 159	09/27/06 - 03:43 PM             #23 I agree with Papez and others ...... it is AICA and the lesion could be hemangioblastoma ? anyways the ans is B
Musuq Forum Guru Topics: 103 Posts: 425	10/26/06 - 09:03 AM             #24 I think is the PICA, but anyway AICA or PICA will give us ATAXIA. B)
