Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory arterial disease that most commonly affects the renal and internal carotid arteries, but intracranial FMD is very rare. We report a patient with FMD involving the posterior cerebral arteries (PCAs). A 24year old female was presented with a 4day history of right homonymous hemianopsia with throbbing headache in the left temporo-occipital area. The brain magnetic resonance imaging (MRI) revealed an acute ischemic stroke in the left PCA territory, while the Time of Flight (TOF) magnetic resonance angiogram (MRA) showed segmental luminal irregularities in the left proximal PCA...

Knowledge about fibromuscular dysplasia (FMD) has broadened over the last several decades. It is no longer considered a rare and benign entity limited to renal arteries and causing just hypertension. It affects other parts of the arterial tree nearly as frequently as the renal arteries. Complications of undiagnosed and untreated extrarenal FMD can be debilitating and life threatening. However, this disease, specifically extrarenal FMD, is not well known to many physicians and patients. Combined with the nonspecific symptoms and signs of the disease, this leads to delayed diagnosis and missed opportunity to prevent serious vascular complications...

BACKGROUND: Renal dysplasia is the most important cause of end-stage renal disease in children. The histopathological characteristic of dysplasia is primitive tubules with fibromuscular disorganization. Renal dysplasia often includes metaplastic cartilage. Metaplastic cartilage in renal dysplasia has been explained as occurring secondary to vesicoureteral reflux (VUR). Additionally, renal dysplasia is observed in renal dysplasia-associated syndromes, which are combinations of multiple developmental malformations and include VACTERL association...

In this case report, we describe a patient with fibromuscular dysplasia who suffered spontaneous bilateral carotid artery dissections. This was followed by significant variations in blood pressure and heart rates during her admission. Unfortunately, during an episode of bradycardia, a premature ventricular contraction occurred during the T wave which resulted in polymorphic ventricular tachycardia. As described in the case and in graphic depiction, this hemodynamic instability resolved after stenting of the carotid artery...

Atypical fibromuscular dysplasia (FMD) is an underdiagnosed cause of ischemic stroke. The typical angiographic pattern of a septum on the posterolateral side of a carotid megabulb is highly suggestive of atypical FMD. We report here on two patients with this highly suggestive pattern of carotid atypical FMD, but which histological examination revealed to be atheromatous lesions. Interestingly, contrast-enhanced ultrasound of the carotid artery showed enhancement of the spur, which should never be the case with an FMD lesion, which has no vasa vasorum...

Spontaneous Coronary Artery Dissection (SCAD) is a non-traumatic and non-iatrogenic separation of the coronary arterial wall. Although uncommon, it should be suspected in any young patient with acute myocardial infarction especially without risk factor of cardiovascular disease. Early coronary angiography is essential in the diagnosis of SCAD. Fibromuscular dysplasia is a rare cause of SCAD, particularly encountered in young women. This is a nonatherosclerotic and noninflammatory vascular disease. Fibromuscular dysplasia may cause stenosis, aneurysm, dissection and / or occlusion of arteries...

Hypertension in children affects 2-5% of the pediatric population. Identifying secondary causes of hypertension is crucial, as some of these entities may be treatable. Renovascular hypertension accounts for 5-10% of the secondary causes of hypertension in children and is mainly related to fibromuscular dysplasia and neurofibromatosis type 1. Ultrasonographic evaluation of the kidneys, including Doppler interrogation, is the recommended primary screening tool. A comprehensive study of the upper abdomen and retroperitoneum allows for identification of additional underlying etiologies...

Spontaneous dissection of the renal artery is a rare phenomenon, and is more common amongst men. It is not a frequent cause of abdominal pain², which is why diagnosis is often late. The case under study is a 45 year old patient that presented sudden pain in the left renal fossa of 12 hours evolution, with no findings from the basic laboratory tests (lab testing, urinary sediment and ultrasound), an abdominal CAT was therefore carried out, which showed areas of renal infarction, as well as an emergency arteriogram, which gave findings of a possible Fibromuscular Dysplasia of the left intrarenal artery as the first diagnostic probability with a partially thrombosed focal dissection...

Fibromuscular dysplasia is a nonatherosclerotic and non-inflammatory vascular disease with primary lesion of renal and internal carotid arteries. We present a neonatal case of fibromuscular dysplasia who died on the second day of life. The newborn suffered from fibromuscular dysplasia of the coronary arteries and a congenital heart defect. The interesting feature of this case was the formation of aneurysms of the coronary arteries with pulmonary atresia. This case demonstrates a casuistically rare form of association between fibromuscular dysplasia of the coronary arteries and pulmonary artery atresia...

Background We report a symptomatic carotid web successfully treated with carotid endarterectomy. A healthy 43-year-old woman presented with acute-onset left-sided weakness. Carotid web was evident on computed tomography angiography as a focal filling defect in the right common carotid artery. This right common carotid artery web extended into the ICA created an eddy resulting in turbulent flow. Subsequent acute embolus formation led to embolization and acute stroke. Method Review of the literature was performed using Medline Plus and PubMed databases...

Fibromuscular dysplasia is a non-inflammatory, non-atherosclerotic vascular disease, occurring predominantly in younger females. A histologically heterogeneous group of fibroplasia without an inflammatory component causes arterial narrowing. It affects mostly one or both renal arteries, cervicocranial or visceral arteries, leading to hypertension, renal failure/renal infarction or stroke/transient ischaemic attack. We present the case of a young female patient with abdominal aortic coarctation, history of acute renal failure, and critical hypertension due to pseudo-occlusion of both renal arteries...

BACKGROUND: Fibromuscular dysplasia (FMD) is an idiopathic, non-inflammatory, non-atherosclerotic vascular disease, resulting in focal narrowing of small and medium-sized arteries. Systematic recording of clinical data in central databases as in the US and France provided new insights into FMD. The main objectives of this multicentre study were to explore the epidemiology, pattern of vascular involvement, clinical manifestations, and management of FMD patients in Flanders. PATIENTS AND METHODS: Multicentre, retrospective registry of patients diagnosed with FMD based on medical imaging...

A wide range of clinically important anatomic variants and pathologic conditions may affect the renal vasculature, and radiologists have a pivotal role in the diagnosis and management of these processes. Because many of these entities may not be suspected clinically, renal artery and vein assessment is an essential application of all imaging modalities. An understanding of the normal vascular anatomy is essential for recognizing clinically important anatomic variants. An understanding of the protocols used to optimize imaging modalities also is necessary...

BACKGROUND: Fibromuscular dysplasia (FMD) and atherosclerotic renal artery stenosis (ARAS) are the most common causes of renovascular hypertension. So far, FMD is believed to cause hypertension via similar mechanisms as in ARAS, that is, a decrease in renal blood flow, which subsequently leads to increased renin secretion. However, given the differences in the blood pressure (BP)-lowering effect of revascularization between patients with ARAS and FMD, we questioned whether this is true...

Background Hemicrania continua (HC) -like headaches have been rarely reported as symptomatic headaches, including cases secondary to cervical artery dissection. Case series We present five cases of HC-like headaches following cervical artery dissection, in three cases with specific indomethacin response. In two cases, comorbidity of fibromuscular dysplasia (FMD) was noted. Conclusion Carotid artery dissection may result in an HC-like headache syndrome. A specific response to indomethacin does not rule out dissection as underlying pathology...

Fibromuscular dysplasia (FMD) is a rare, segmental, nonatheromatous, and noninflammatory arterial disease of unknown etiology. It predominantly involves renal artery (60-75%) followed by extracranial part of the internal carotid artery and vertebral arteries (25-30%). The disease typically affects middle-aged women and involves intermediate-sized arteries throughout the body. There are rare case reports of extracranial FMD compounding a trauma case. A patient was brought to trauma center emergency with a history of fall from height...

Fibromuscular dysplasia (FMD) is a rare condition that causes structural compromise of the blood vessel presenting either as an incidental radiological finding, dissection or stenosis usually of the renal or craniocervical arteries. Seldom, patients present with spontaneous dissection in visceral arteries and there are few reports of hepatic involvement. This report outlines the case of a 43-year-old female who presented with severe right upper quadrant pain with a subsequent diagnosis of FMD manifesting as spontaneous hepatic artery dissection...
