A Case of Fibromuscular dysplasia involoving the left internal carotid and middle cerebral rtery in a previously healthy man is presented. Symptoms were characteristic of cerebral schemia in the territory that the left middle cerbral artery supplies. This case suggests that The fibromuscular dysplasia is one of the causes provoking cerebral infarction.

Fibromuscular dysplasia (FMD) is a rare, segmental nonatheromatous angiopathy of unknown etiology affecting small to medium-sized arteries. The most common angiographic pattern is the classic string-of-beads appearance. But the tubular stenosis type of the FMD is a rare finding and has not been reported previously. We report a case who presented with recurrent intracerebral hemorrhages, whose angiographic features were long tubular stenosis type of FMD affecting the both internal carotid arteries associated with terminal carotid occlusions.

Fibromuscular dysplasia (FMD) is a segmental nonatheromatous and noninflammatory angiopathy of unknown cause. Despite the unknown origin Of FMD, it has been recognized in the extracranial internal cartid, vertebral, and intracranial arteries. Usually the diagonsis of FMD has been done by angiographic findings, and pathologically proven cases are very rare. We report 2 patients who had suffered from hemicranial pain and ipsilateral ama-urosis figax, and whose initial laboratory evaluations revealed high ESR. The biopsy was done in the temporal artery under the impression of the temporal arteritis, which showed the findings of the fibromuscular dysplasia.

Stenotic or hypoplastic coronary arteries occupy vital features in the clinical situations. The pseudohypoplasia might be defined as a macroscopic hypoplasia based on the diameter of an artery compared with contralateral artery but is not hypoplasia both anatomically and histopathologically. During a routine dissection course, a pseudohypoplasia in right coronary artery was recognized in an 82-year-old Korean female cadaver who had a common mesenteric trunk and a fibromuscular dysplasia in the left vertebral artery. Although macroscopic hypoplasia was discovered, the right coronary artery had normal anatomical features and the left coronary artery showed atherosclerotic changes on the main trunk. The right coronary artery was misread to have hypoplasia due to atherosclerotic aneurysm on left coronary artery. Since macroscopic hypoplasia in radiological and surgical situations may lead to confusion to interpret its pathophysiology just like this case, the better anatomical knowledge on the coronary artery can help to prevent misleading approaches.

Renal artery stenosis (RAS) is one of the most common primary diseases of the renal arteries. It is associated with hypertension as well as ischemic renal disease. Its concomitant presence constitutes a high cardiovascular risk, thus timely diagnosis is important. This study aims to determine the occurrence of RAS in patients undergoing abdominal CT angiography and determines other factors that predict the highest-risk subset who have signifi cant renal artery narrowing. A retrospective review of records of 470 patients who underwent CT angiography of the whole abdomen was done. RAS occurs in about 9.57% of patients who had a CT scan of the whole abdomen. Older patients, patients with heart disease and patients with more atherosclerotic vessels in the abdomen increases the risk for signifi cant RAS (p values of 0.005, 0.008 and <0.001, respectively). Diabetes, hypertension as well as other imaging fi ndings such as the presence of aneurysm elsewhere seen in the abdominal scans and renal artery duplication do not statistically correlate with the increased risk for RAS in this study

The etiology of ischemic stroke in young adults often remains unclear. Extracranial internal carotid artery (ICA) vasospasm is uncommon and has been reported in only a few cases. We present a case of migrainous headache and recurrent ischemic stroke due to recurrent extracranial ICA vasospasm without evidence of carotid artery dissection or fibromuscular dysplasia.

Spontaneous renal artery dissection is an uncommon cause of renal infarction. Previous reports of spontaneous renal artery dissection has been associated with hypertension or fibromuscular dysplasia. We report herein the case of a previously healthy, normotensive patient with renal infarction due to spontaneous renal artery dissection who remained normotensive throughout his course without therapy. A previously healthy 31-year-old man with well- documented normotension had a sudden onset of right flank pain and delayed onset of elevation of lactic dehydrogenase, hematuria, and proteinuria. Thin section spiral computerized tomogram shows linear intraluminal filling defect suggesting intimal flap. Angiography shows dissection of main right renal artery. Six months later, he has remained well and normotensive without therapy. To our knowledge, this is the first case of spontaneous renal artery dissection in normotensive patients in Korea.

Fibromuscular dysplasia (FMD) is an uncommon hyperplastic disorder affecting medium-sized arteries. It can lead to renovascular hypertension, sometimes associated with dissection. But it rarely causes renal infarction. We here report a case of recurrent renal infarction due to FMD. A previously healthy 29- year-old man presented with acute onset of right flank pain. He had been treated for the same symptom 8 years ago. Abdominal CT scan showed renal infarction at upper pole of right kidney. Renal arteriography demonstrated string of bead, consistent with FMD. It showed also old renal infarction at lower pole of right kidney. To our knowledge, recurrent renal infarction due to FMD has not been previously reported.
