Abstract
Behcet's disease (BD) is a chronic systemic inflammatory vasculitis with a relapsing and remitting course. The disease predominantly affects males between the ages of 20 and 40 years. The disease is more prevalent in Middle Eastern and Asian countries but is less common in North American countries. BD typically presents as recurrent oro-genital ulcers and ocular inflammation. Pulmonary vasculitis with pulmonary arterial involvement is a unique manifestation, with most pulmonary manifestations occurring later in the disease course. Here, we report a case with pulmonary arterial aneurysms and variable arterial-venous thrombosis in a young African American Male diagnosed with BD after he presented with pulmonary manifestations. This report emphasizes that a high index of suspicion is needed to diagnose a rare condition with such variable manifestations as Behcet's disease and that early detection and immunosuppression therapy can confer improved prognosis.

Quantitative analysis of lung parenchymal involvement in Behçet's disease by the novel automatic program. Int J Rheum Dis 2023; 26:917-921. [PMID: 36946548 DOI: 10.1111/1756-185x.14673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/18/2023] [Accepted: 03/10/2023] [Indexed: 03/23/2023]
Abstract
OBJECTIVES We aimed to quantitatively analyze lung parenchymal changes in Behçet's patients and to detect early parenchymal quantitative changes that occur in the absence of positive visual radiological findings. METHODS In our study, a total of 31 patients with Behçet's disease, 17 with positive radiological findings and 14 patients without positive radiological findings, and a control group of 33 individuals were evaluated. The automatic program determined lung volumes, lung densities, and opacity volume percentages by evaluating the contrast-enhanced lung computed tomography scans. RESULTS The total lung volume was 3632.98 ± 1100.53 mL in the Behçet's disease patient group and 4925.70 ± 1098.88 mL in the control group, and there was a significant decrease in the total lung volume in Behçet's disease patients (P < 0.0001). The mean lung density was -723.73 ± 65.16 in the Behçet's disease patient group and -767.35 ± 41.17 in the control group, and there was a significant increase in the mean density in the Behçet's patients (P = 0.0023). A significantly higher correlation was observed between lung density and lung volume in Behçet's patients (P < 0.0001, r = -0.795). The lung volume of Behçet's disease patients with negative radiological findings was significantly lower than that of the control group (P = 0.0342). CONCLUSIONS Lung volumetric changes in Behçet's disease patients are the quantitative data most affected by the disease. In addition, lung volume decreases in Behçet's patients who do not have visual parenchymal involvement.

Clinical characteristics of pulmonary artery involvement in patients with Behçet's syndrome: single-centre experience of 61 patients. Clin Rheumatol 2021; 40:4127-4134. [PMID: 33907905 DOI: 10.1007/s10067-021-05748-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 04/18/2021] [Accepted: 04/21/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To report the clinical characteristics of pulmonary artery involvement (PAI) in patients with Behçet's syndrome (BS) and to define the predictors of relapses. METHODS We performed retrospective analysis of BS patients with PAI who fulfilled international study group criteria. Among 460 patients with vascular Behçet's syndrome (VBS), 66 were diagnosed with PAI. For final analyses, 61 patients with PAI were included who had at least 2 follow-up visits (72.1% male, mean age at BS diagnosis 29.34 ± 10.1 years). The patient data were recorded. Relapse was defined as the reoccurrence of vascular event in any vascular structure. Factors associated with relapse were assessed by logistic regression analysis. RESULTS There were no differences considering demographic and clinical features of the patients with and without PAI in the VBS group, except that intracardiac thrombosis was more common in the patients with PAI (19.7% vs 0.3%). Among 61 patients, 50 (82.0%) had isolated pulmonary artery thrombosis (PAT), whereas 11 (18.0%) had pulmonary artery aneurysm with or without PAT. Twenty-four (39.3%) patients experienced vascular relapse during median follow-up of 65.9 (Q1-Q3: 20.1-109.0) months. To define the factors associated with relapses, patients with isolated PAT were analysed. On multivariable logistic regression analysis, older age at BS diagnosis and anticoagulation usage seemed to be protective (OR: 0.92, 95% CI 0.86-1.02, OR: 0.34, 95% CI 0.09-1.33, respectively). CONCLUSION Our results indicate a higher frequency of intracardiac thrombosis in BS patients with PAI and possible efficacy of anticoagulation usage in preventing relapses. Key Points • This study shows that intracardiac and intracranial thromboses are seen more frequently in patients with PAI and the prevalence of pulmonary artery thrombosis has been increasing in the case of PAI. Furthermore, our report indicates that anticoagulation might be effective in preventing further vascular relapses.

Thoracic Complications in Behçet's Disease: Imaging Findings. Can Respir J 2020; 2020:4649081.

Abstract
Behçet's disease (BD) causes vascular inflammation and necrosis in a wide range of organs and tissues. In the thorax, it may cause vascular complications, affecting the aorta, brachiocephalic arteries, bronchial arteries, pulmonary arteries, pulmonary veins, capillaries, and mediastinal and thoracic inlet veins. In BD, chest radiograph is commonly used for the initial assessment of pulmonary symptoms and complications and for follow-up and establishment of the response to treatment. With the advancement of helical or multislice computed tomography (CT) technologies, such noninvasive imaging techniques have been employed for the diagnosis of vascular lesions, vascular complications, and pulmonary parenchymal manifestations of BD. CT scan (especially, CT angiography) has been used to determine the presence and severity of pulmonary complications without resorting to more invasive procedures, in conjunction with gadolinium-enhanced three-dimensional (3D) gradient-echo magnetic resonance (MR) imaging with the subtraction of arterial phase images. These radiologic methods have characteristics that are complementary to each other in diagnosis of the thoracic complications in BD. 3D ultrashort echo time (UTE) MR imaging (MRI) could potentially yield superior image quality for pulmonary vessels and lung parenchyma when compared with breath-hold 3D MR angiography.

Abstract
In the present study, multi-slice CT results of patients with Behçet's disease (BD) and vascular complications were retrospectively evaluated. From January 2016 to May 2018, 45 of 361 patients with BD were diagnosed with vascular involvement. The clinical background, laboratory parameters and response to therapy of those patients were assessed. The following characteristics of vascular aneurysms were analyzed: Maximum diameter, length, wall thickness, borders, luminal changes, mural thrombus, cystic change of the vessel walls, asymmetric bulging of the right part of the aortic wall (RP type) and calcific plaques. The 45 BD patients analyzed included 37 males and 8 females with a median age of 40 years (30–49 years). Significant differences were observed among genders regarding age, ocular disorders and digestive-tract ulceration. A total of 42 aneurysms were identified with a mean diameter of 43 mm. Most aneurysmal walls (88%) were homogeneously enhanced on contrast-enhanced CT. Comparison of groups classified by aortic and larger arterial aneurysms indicated that aneurysms occurring in the aorta were more likely to form a mural thrombus, have a thicker wall (P<0.001) and unclear borders (P=0.036), to be of the RP type (P=0.003) and have a longer extension (P=0.001) compared with those in larger arteries. Unclear border of the aneurysmal wall was the only radiologic predictor correlated with an elevated erythrocyte sedimentation rate (P<0.001). In conclusion, characteristic CT imaging features of aneurysms may help to diagnose vascular involvement of BD and assess its severity, particularly in the absence of the classical clinical manifestations.

Abstract
The hallmark of vasculitis is autoimmune inflammation of blood vessels and surrounding tissues, resulting in an array of constitutional symptoms and organ damage. The lung is commonly targeted in the more familiar ANCA-associated small vessel vasculitidies, but large and medium vessel vasculitides, including Takayasu arteritis, giant cell arteritis, polyarteritis nodosa, Behcet's disease, and necrotizing sarcoid granulomatosis, may also feature prominent pulmonary involvement. Pulmonary manifestations of these conditions include pulmonary arterial aneurysms, pulmonary hypertension, diffuse alveolar hemorrhage, pulmonary nodules, and parenchymal infiltrates. An understanding of the diverse manifestations of vasculitis and a high index of clinical suspicion are essential to avoid delays in disease recognition that may result in permanent or life threatening morbidity. In this review, we outline the general clinical manifestations, pulmonary manifestations, diagnostic workup, imaging findings, and treatment of medium, large, and variable vessel vasculitides.

Abstract
We described disease characteristics, management and outcome of a group of Behçet's syndrome (BS) patients who underwent pulmonary lobectomy, segmentectomy or various pleura interventions for complications due to pulmonary artery or descending aorta involvement. There were 9 patients with BS (8 M/1 F; mean age: 24.8 ± 7.5 and mean disease duration: 4.3 ± 3.8 years) who underwent lung surgery from 2000 to 2017. Their medical files including operation details and radiological and pathological studies were reviewed retrospectively. Lobectomy was done in 6 patients, decortications and pleura interventions in the remaining 3. The reason for the surgical procedures were giant pulmonary arterial aneurysms refractory to the medical treatment (n = 4), pneumothorax due to large cavities (n = 2), pleural effusions refractory to the medical treatment (n = 1), a bronchopleural fistula after embolization (n = 1) and bronchiectasis (n = 1). All patients received medical treatment with cyclophosphamide and corticosteroids before the surgical interventions. The histological examination in patients with pseudo-aneurysms showed destruction of medial elastic fibers, inflammatory cell infiltration of adventitial tissues and penetration into the adjacent bronchi with adherent thrombi. Two patients died: one due to Budd-Chiari syndrome 1 year after the surgery, another because of a massive hemoptysis 3 months after lobectomy. The remaining 7 patients are still alive with a median follow-up of 8 years (inter-quartile range [IQR]: 4-11). Lobectomies in BS patients with giant pulmonary aneurysms refractory to medical treatment can be done with favorable outcome. Also, complications such as large cavities causing pneumothorax, refractory pleural effusions, bronchiectasis, and embolization complications can be managed effectively with surgical interventions.

Abstract
Hemoptysis is a life-threatening complication of Behcet's disease that is likely related to pulmonary artery aneurysm (PAA). Vascular interventional radiology may offer effective emergency therapeutic option, but has not been thoroughly investigated in this setting. A case series of a French referral center for hemoptysis combined with a literature review of case reports was conducted. Between 1995 and 2016, 12 patients were referred to our center for hemoptysis revealing or complicating the course of Behcet's disease. Pulmonary artery aneurysm (PAA) was the mechanism of hemoptysis in ten patients, nine of whom were treated by a transcatheter embolotherapy. Combining an additional 8 case reports from the literature, 17 patients treated by transcatheter embolotherapy for PAA were analyzed. The duration of the course of Behcet's disease was 22 months [IQR 3-45] at the time of PAA diagnosis. Transcatheter embolotherapy of PAA was successful for immediately controlling hemoptysis in all patients, without major complication except for one. Hemoptysis recurred in seven patients (41%) within 5 months [IQR 1-12]. The use of coils for transcatheter embolotherapy was associated with hemoptysis recurrence. A bronchosystemic hypervascularization related to the previously occluded PAA was the main mechanism of bleeding recurrence, leading to bronchosystemic artery embolization in four patients and surgery in two patients. Behcet's disease-related hemoptysis is mainly due to PAA. Transcatheter embolotherapy should be considered as the first-line emergency treatment for PAA-related hemoptysis, in association with the immunosuppressive regimen. Hemoptysis may recur in half of the cases, involving preferentially a bronchosystemic arterial mechanism.

Abstract
Behcet's disease is a multi-systemic and chronic inflammatory vasculitis of unknown etiology characterized by recurrent oral and genital ulcers, uveitis, arthritis, arterial aneurysms, venous thrombosis, skin lesions and GIS lesions. Although pulmonary artery aneurysms are rare, it is a critical condition due to high risk of rupture. Venous involvement of Behcet's disease primarily occurs in the lower extremities. In the presence of deep vein thrombosis(DVT) and pulmonary embolism, the mainstay of treatment in Behcet's disease is immunosuppressant therapy. Anticoagulants can be used only after initiation of immunosuppressant therapy and suppression of the disease. Anticoagulant therapy alone may lead to fatal hemoptysis. We report the case of a 24 year-old patient who presented to the emergency service with complaints of shortness of breath, general condition disorder and hemoptyhis while using warfarin for DVT and whose thoracic CT angiography showed pulmonary embolism and pulmonary artery aneurysm and diagnosed with Behcet's disease.

Abstract
AIM In this study we investigated the frequency and characteristics of pulmonary manifestations in a group of patients with Behcet's disease (BD) who were admitted to Cairo University Hospital. METHODS Fifteen patients were included in our study, 14 men (93.3%) and one woman (6.66%).Their mean age was 30.06 ± 9.8 years and the mean age of onset of BD was 23.7 ± 5.54 years. All patients were subjected to full history taking, clinical examination, plain chest X-ray and helical computed tomography (CT) study of the chest. RESULTS Pulmonary involvements were detected in 11 patients with BD, 73.3% of cases: 10 men (90.9%) and one woman (9.09%).Their mean age was 28.8 ± 8.07, the mean age of onset of BD was 23.2 ± 5.59 years and the mean disease duration until lung manifestations appear was 3.7 ± 4.8 years. The main pulmonary and constitutional symptoms in these 11 patients were as follows: dyspnea 81.8%, cough 63.6%, weight loss 63.6%, chest tightness 54.5%, hemoptysis 45%, massive hemoptysis 27.2%, fever 36.3% and expectoration 36.3. Analysis of both vascular and parenchymal lung lesions in helical CT scan in the 11 patients with BD were as follows: pulmonary artery aneurysm (PAA) occurred in 5/11 patients (45.4%), pulmonary nodules occurred in 3/11 patients (27.2%), pleural effusion occurred in 3/11 patients (27.2%), pulmonary embolism and infarction occurred in 1/11 patients (9.09%) and pneumonitis occurred in 1/11 patients (9.09%). CONCLUSION The higher frequency of pulmonary manifestations in our patients (73.3%) and the higher frequency of PAA (33.3%) could be related to the fact that this study was conducted on a group of patients who were admitted to the hospital with more severe illnesses.

Abstract
Behçet disease (BD) is a multisystem disorder, with vasculitis as its underlying pathological process, in contrast to the classic triad of recurrent oral and genital ulcerations, with uveitis. Vascular involvement in BD includes venous thrombosis, arterial occlusion, and pulmonary artery and aortic aneurysm formation. Cardiac involvement is rare and often obscure. It includes intracardiac thrombi formation, and is associated with a poor prognosis. Our objectives are to describe two cases with BD, complicated with vascular and cardiac involvement, and to raise awareness of these rare complications, the needed routine surveillance, and thus to prevent inappropriate interventions, serious outcomes, and mortality. We present two male patients from the Mediterranean Basin with BD. The first was diagnosed early as a BD patient. The second was diagnosed at the time of cardiovascular (CV) involvement. We recommend that patients who are diagnosed, or even suspected of suffering from BD, especially in endemic areas along the Silk Route pathway, should be followed up routinely for CV involvement, even if rare, obscure, or with a bizarre presentation.

Abstract
Diffuse alveolar hemorrhage (DAH) is a clinical syndrome characterized by generalized intra-alveolar bleeding originating from the pulmonary microcirculation. The finding of DAH carries an extended differential diagnosis and may be associated with a number of histopathologic patterns. The prompt recognition and diagnosis of DAH is of critical importance to the practicing clinician as accurate diagnosis and prompt initiation of therapy may dramatically improve patient outcomes. This chapter reviews the diagnosis and management of diffuse alveolar hemorrhage.

Abstract
Behçet's disease is an inflammatory disorder of unknown etiology, characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. Many abnormal echocardiographic findings have been previously reported in patients with Behçet's disease. Some of these; namely, aortic root dilation, aortic valve regurgitation, intracardiac thrombi, and pulmonary artery aneurysm may precede other manifestations of the disease and occasionally require surgical intervention for proper management. Compared to patients without Behçet's disease, management of these complications in patients with the disease is challenging and requires different treatment strategies. If diagnosis of Behçet's disease is missed prior to surgical intervention, higher incidence of surgical failure, recurrence, and even higher postoperative mortality may occur. In this review, the author discusses these major cardiac complications of Behçet's disease.

Major vascular involvement in Behçet's disease: a retrospective study of 796 patients. Clin Rheumatol 2013; 32:845-52.

Abstract
Behçet's disease (BD) is a multi-systemic inflammatory disorder which can affect all types and sizes of blood vessels. This study aims to evaluate the prevalence and characteristics of vascular involvement in BD. Among 796 patients diagnosed with BD, 102 patients (81 male, 21 female) with vascular involvement were included, whose detailed clinical characteristics were recorded. The diagnosis of vascular lesions was made on clinical signs, by Doppler ultrasonography, and/or angiography using computed tomographic or magnetic resonance techniques. Vascular involvement occurred in 12.8 % of BD patients. Male to female ratio was 3.86:1. Mean age at onset of vascular involvement was 29.5 ± 11.3 years. Vascular lesion was the initial sign of BD in 28 patients, accounting for 27.5 %. Of 102 BD patients with vascular involvement, 72 had venous lesions (70.6 %) and 56 had arterial lesions (54.9 %), among which 26 (25.5 %) patients had both venous and arterial involvements. Female BD patients were more often involved with arterial lesions, whereas male BD patients developed venous lesions more often than females, P = 0.000. The most common type of vascular involvement was deep venous thrombosis in lower extremities (n = 49), other affected venous sites including inferior vena cava, superior vena cava, and cerebral venous. The prominent type of arterial lesions was dilatation (n = 25, including 24 cases of aneurysms); other types included eight cases of occlusion and 23 cases of stenosis. The main locations of arterial lesions were the aorta (n = 19), lower extremity arteries (n = 15), pulmonary arteries (n = 13), coronary arteries (n = 5), and subclavian arteries (n = 5). Compared with those without vascular lesions, ocular involvement, genital ulcers, and arthritis were significantly less frequent among patients with vasculo-BD (23.5 vs 35.2 %, P = 0.024; 54.9 vs 76.5 %, P = 0.000; 19.6 vs 30.5 %, P = 0.026), whereas a higher frequency of cardiac involvement was found in vasculo-BD patients (20.6 vs 3.6 %, P = 0.000). Vascular involvement is a complication in BD patients. This study illustrated that venous lesions are more frequently involved than arterial lesions. Vascular lesions correlated with a high frequency of cardiac involvement and a low incidence of ocular lesions, genital ulcers, and arthritis.

Abstract
BehçetDisease (BD) is a systemic vasculitis characterized by recurrent oral and genital ulcers and uveitis, arthritis, and involvement of the gastrointestinal tract, central nervous system and blood vessels. The aneurysms of the pulmonary arteries, with or without thrombosis, are typical manifestation of BD. We report a case with BD, pulmonary arterial aneurysms(PAA) and in situ thrombosis. We aimed to show the effectiveness of immunosuppressive treatment on in situ thrombosis in a case with PAA and BD.

Abstract
The aim of this study was to evaluate circulating intercellular adhesion molecule-1 (cICAM-1) in serum and in bronchoalveolar lavage (BAL), as a marker for the inflammatory process in patients with active Behçet's disease (BD). Circulating ICAM-1 was tested by an enzyme linked immuno-sorbent assay in serum and in BAL of patients with BD. These values were compared to those of patients with tuberculosis and to healthy controls. Increased levels of circulating ICAM-1 were found in serum from patients with active BD compared to healthy controls (p < 0.01). Similar levels of serum cICAM-1 were found in BD and tuberculosis. Additionally, both BD and tuberculosis patients exhibited high levels of cICAM-1 in BAL fluid, suggesting that this increase may be a result of the immune system activation in inflammatory sites. Circulating ICAM-1 seemed to have a good discriminative power in identifying active BD, being elevated in all active stages (p < 0.01) compared to remission BD stage. No differences were found in active BD patients depending upon the clinical manifestations. These results suggest that cICAM-1 may be involved in leucocyte adhesion and migration into the vessel wall of the lung. Circulating forms are derived from molecules expressed on the surface of activated cells, as a result of an inflammatory process.

Abstract
Pulmonary artery aneurysms (PAAs) are well known causes of mortality and morbidity in Behçet disease (BD). However, pulmonary artery involvement in BD is not limited to PAA; the other main type of pulmonary artery involvement is pulmonary artery thrombus (PAT), with or without associated PAA. In addition, other types of lung disease like nodules and cavities in the lung parenchyma are frequently associated with pulmonary artery involvement, and can be misinterpreted as being due to infection. We surveyed the clinical, radiologic, and laboratory characteristics and outcome of 47 BD patients with pulmonary artery involvement and the associated findings, all seen and followed at a single dedicated tertiary care center.We identified 47 (41 male, 6 female) patients in whom pulmonary artery involvement was diagnosed, who were registered in the multidisciplinary clinic at Cerrahpasa Medical Faculty between January 2000 and December 2007. Mean age at diagnosis was 29 ± 8 years, and mean disease duration to the onset of pulmonary artery involvement was 3.6 ± 4.8 years. Hemoptysis was the most common presenting symptom (79%) followed by cough, fever, dyspnea, and pleuritic chest pain. Thirty-four of 47 patients (72%) presented with PAA, including 8 with associated PAT. The remaining 13 patients (28%) had isolated PAT. Patients with isolated PAT in general have clinical features similar to patients with PAA. However, hemoptysis was less frequent and voluminous in patients with isolated PAT. Most (91%) of the patients had active disease outside the lungs when they presented with pulmonary artery involvement.Forty (85%) patients had nodules and 6 (13%) had cavities when first seen. Peripheral venous thrombosis was present in 36 of 47 (77%) patients, and intracardiac thrombi in 12 of the 36 (33%) patients. Nodules, cavities, and intracardiac thrombi were mainly present in the acute stages of pulmonary artery involvement.Pulmonary artery involvement is usually multiple, and involves mostly descending branches of the pulmonary artery. Pulmonary artery involvement may disappear, but arterial stenosis or occlusions usually develop at the same location. After a mean follow-up of 7 years, 12 of 47 (26%) patients were dead; patients with larger aneurysms were more likely to die. Sixteen of 47 (34%) patients were symptom free, and the remaining 40% had mild dyspnea (13/47) and/or small bouts of hemoptysis (8/47).Pulmonary artery pressure may be elevated, and may indicate a poor prognosis. Mediastinal lymphadenopathy and mild pleural and pericardial effusions may also be observed. Corticosteroids and immunosuppressive agents are the mainstays of treatment; however, refractory cases may require embolization, lobectomy, cavitectomy, and decortication.

Abstract
PURPOSE This study aims to demonstrate pulmonary alterations (PA) in patients with Behcet's disease by using CT. MATERIALS AND METHODS CTs of 50 patients with Behcet's disease and 20 others in a control group have been evaluated retrospectively for PA (septal, reticular, nodular, atelectatic opacities). RESULTS Eight out of 50 patients (16%) with Behcet's disease showed PA. Three out of 20 (15%) in the control group showed PA. No differences were observed between Behcet's disease patients and the control group regarding pulmonary alterations (p=0.917). No differences were observed in the disease duration, ages and sex in either group in those with and without PA. CONCLUSION Pulmonary alterations can be seen in patients with Behcet's disease, but these alterations are not significant.

Abstract
The collagen vascular diseases, also referred to as connective tissue diseases, are a diverse group of systemic inflammatory disorders thought to be immunologically mediated. The concept of collagen vascular disease began to take shape in the 1930s, when it was recognized that rheumatic fever and rheumatoid arthritis can affect connective tissues throughout the body.1,2 During the following decade, as conditions such as systemic lupus erythematosus (SLE) and scleroderma came to be viewed as systemic diseases of connective tissue, the terms diffuse connective disease and diffuse collagen disease were proposed.3,4 During the same period, the designation of diffuse vascular disease was proposed for diseases such as scleroderma, polymyositis, SLE, and polyarteritis nodosa, which featured widespread vascular involvement.5 With the realization that many of these entities can exhibit both systemic connective tissue manifestations and vascular abnormalities, the unifying designation of collagen vascular disease was introduced.6

Abstract
BACKGROUND Behçet's disease (BD) is a multisystem vasculitis and pulmonary involvement in BD is reported to indicate poor prognosis and high mortality. OBJECTIVES The aims of this study were to report on patients with pulmonary involvement and to discuss pulmonary artery thrombus and small-sized vasculitis associated with BD, with respect to previously published cases. METHODS Fifteen patients with BD and pulmonary involvement were included in this study. Massive hemoptysis was observed in all patients having pulmonary artery aneurysm (PAA). RESULTS Eleven patients had macroscopic pulmonary vascular disease (2 PAA, 3 PAA and thrombi and 6 only thrombi) and 3 patients had microscopic pulmonary vascular disease. The remaining patient had pulmonary cryptococcosis. CONCLUSIONS Data regarding treatment and outcomes of patients having BD-related pulmonary emboli/infarct and small-sized vasculitis are limited. Pulmonary vasculitis affects different levels of the pulmonary artery in BD and should be classified as macroscopic and microscopic vascular disease. 'Pulmonary artery thrombosis' should be used instead of 'pulmonary emboli'. Spiral CT angiography is the best radiological tool for evaluation of pulmonary problems in BD. Treatment of vasculitis should be based on the type of vascular disease and may vary among different types of vascular disease. Anticoagulation can be used in patients with microscopic vascular disease and nonaneurysmal macroscopic vascular disease. More studies are needed to clarify this issue.

Abstract
Pulmonary artery aneurysm is the best-defined type of pulmonary disease in Behçet's disease (BD) with an important morbidity and mortality. The objective of this study was to assess the contribution of high-resolution dynamic chest CT imaging for one of the most serious aspects of BD: pulmonary artery aneurysm and other pulmonary parenchymal involvement. Sixteen BD patients were recruited for this study, (14 men, 87.5%, and 2 women, 12.5%). All patients fulfilled the 1990 American College of Rheumatology criteria for classification of BD [International Study Group for Behçet's Disease, Lancet 335:1078-1080, (1990)]. All patients underwent thorough history taking, full clinical examination, and routine laboratory investigations. Plain chest X-rays and pulmonary CT angiography were performed on all patients in an attempt to assess the pulmonary vasculature and lung parenchyma. Pulmonary vascular abnormalities were as follows: pulmonary artery aneurysms of varying sizes in nine patients (56.3%), main pulmonary artery ectasia in two patients (12.5%), pulmonary artery embolism in two patients (12.5%), venacaval thrombosis in seven patients (43.8%), and pulmonary venous varices in four patients (25%). Pulmonary parenchymal abnormalities were as follows: three patients (18.8%) with mild central bronchiectasis, one patient (6.3%) with atelectasis, one patient (6.3%) with subpleural nodule, and four patients (25%) with interstitial lung disease. Eight of the male patients were smokers. Multislice CT is useful in demonstrating the entire spectrum of thoracic manifestations of BD. Multislice CT is noninvasive and provides excellent delineation of the vessel lumen and wall and perivascular tissues, as well as detailed information concerning the lung parenchyma, pleura, and mediastinal structures.

Abstract
Type IV Ehlers-Danlos syndrome (EDS) is the only lethal form of EDS, mostly due to vascular complications. We describe a patient suffering from EDS type IV who presented with right thromboembolic renal infarctions due to a right renal artery aneurysm. We preferred observation to anticoagulation therapy because the thrombus in the renal artery aneurysm sealed the pending rupture of the arterial wall. This unusual embolic presentation of EDS exemplifies problematic aspects in the management of these patients.

Abstract
A 20-year-old man with Behcet's disease characterized by recurrent arterial aneurysms presented with a new aortic root aneurysm. This patient previously had aneurysms of the coronary arteries and vein, as well as ruptured renal artery aneurysm. Chronic maintenance immunosuppressive therapy was recommended due to the catastrophic nature of the disease, which the patient refused to take. The patient died shortly after admission. This case demonstrates the unique catastrophic natural history of vascular Behcet's disease with recurrent life-threatening arterial events, and this case stresses the therapeutic dilemma of maintenance immunosuppressive therapy in selected patients.

Pulmonary artery aneurysms due to Behçet's disease are mainly seen in young males and very rarely in females. To our knowledge there are only 10 cases reported in the related literature. Emergent transcatheter embolization was performed in a female patient with a known history of Behçet's disease in whom massive hemoptysis developed because of rupture of a giant pulmonary artery aneurysm. At 6-month follow-up, transformation of the aneurysm sac into an air cavity was detected. To our knowledge, such a transformation has never been reported in the literature before. Embolization of the pulmonary artery aneurysm and the mechanism of cavity transformation are reviewed and discussed.

Abstract
STUDY OBJECTIVES The aims of this study were to investigate the frequency of pulmonary problems in Behçet disease (BD), and to discuss lesser-known features of pulmonary BD such as clinical characteristics, analysis of prognosis, and evaluation of treatment options with respect to the previously published cases. DESIGN We conducted a comprehensive review of the literature to analyze cumulated data about pulmonary involvement in BD. SETTING We found 159 articles regarding pulmonary disease associated with BD in May 2003. PATIENTS The evaluation of these articles demonstrated 598 pulmonary problems in 585 cases. RESULTS Pulmonary artery aneurysms (PAAs) are the most common pulmonary lesion in BD, and these are almost always associated with hemoptysis. Seventy-eight percent of patients with aneurysms have concomitant extrapulmonary venous thrombi or thrombophlebitis. Other pulmonary problems are reported in BD, and these are principally related to vascular lesions and radiologic abnormalities. CONCLUSIONS Pulmonary vascular problems, either PAA or involvement of small-sized vessels, are the main pulmonary disorders in BD. Immunopathologic findings indicate that the underlying pathogenesis is pulmonary vasculitis, which may result in thrombosis, infarction, hemorrhage, and PAA formation. Patients with small nonspecific radiologic abnormalities should be followed up closely since early diagnosis of vascular lesions may be life-saving. Immunosuppression is the main therapy for the treatment of a vasculitis. It is important that pulmonary angiitis is not mistaken for pulmonary thromboembolic disease since fatalities have occurred in BD shortly after initiation of anticoagulation/thrombolytic treatment.

Abstract
INTRODUCTION We present our experience with surgical treatment of arterial complications in Behcet disease (vasculo-Behcet disease), and the long-term results and pitfalls of surgical treatment. MATERIAL AND METHODS Between January 1990 and January 2003, 20 consecutive patients underwent surgery to treat vasculo-Behcet disease. Most patients (17 of 20) were men, with mean age of 38.4 years. RESULTS Thirty-four operations were performed in 20 patients. The operative mortality rate was 5.8% (2 patients). There were 17 emergency operations, 6 because of ruptured primary abdominal aneurysms. There were five others with critical limb ischemia, resulting in 3 amputations. All patients were followed up postoperatively on average for 44 months (range, 6 months-14 years). Two additional patients were lost to follow-up. After the initial operation 10-year survival rate was 30%, 10-year complication-free survival rate was 13%, and 5-year repeat operation-free survival rate was 26%. CONCLUSION Although surgical intervention should be postponed until active inflammation has subsided, often this is not possible, because of the emergent nature of these problems. Most arterial complications of vasculo-Behcet disease present with a pseudoaneurysm rupture or with impending rupture. An aggressive surgical approach can be life-saving in such instances, and should be undertaken regardless of long-term complications, which are more common when the operation is performed in the presence of active inflammation. Early and late results can be improved by individualizing, selecting a disease-free area for reconstruction, and eliminating use of autologous graft material.

Abstract
Diffuse alveolar hemorrhage represents a medical emergency, and clinicians must have an expedient approach to its identification. There are many causes of diffuse alveolar hemorrhage, including vasculitides, immunologic conditions such as Goodpasture's syndrome, collagen vascular disease, and idiopathic conditions. Careful attention to the medical history, physical examination, and targeted laboratory evaluation often suggests the underlying cause. Patients in whom the diagnosis of diffuse alveolar hemorrhage remains uncertain should undergo diagnostic bronchoscopy. In patients with evidence of diffuse alveolar hemorrhage and renal involvement, kidney biopsy should be considered to identify the underlying cause and help direct therapy.

Abstract
Behçet's disease (BD) is a chronic, relapsing, systemic inflammatory vasculitis of unknown aetiology with a myriad of immunological and pathological consequences. Patients with BD are clustered along the ancient silk road, extending from Far-East Asia to Turkey. The disease affects both genders of all ages from infants to the elderly. It is a long-term, cyclical disease and such patients may have symptom-free periods of weeks, months or years that are interrupted by exacerbations of varying intensities lasting a few days, weeks or months. Clinical features include oral aphthae, genital ulcers, ocular inflammation, skin lesions, as well as articular, vascular, neurological, pulmonary, gastrointestinal, renal and genitourinary manifestations. The main histopathological finding is a widespread vasculitis of the arteries and veins of any size or thrombophilia according to the site of involvement. BD may start with just one or two small symptoms but other symptoms may gradually appear over the years. Recurrent ocular inflammation, which occurs in approximately 50% of cases, is the major morbidity that may eventually lead to blindness. The treatment of BD is usually symptomatic and palliative. Therefore, the main objectives are to relieve symptoms associated with mucocutaneous lesions and arthritis, to modify the course of the disease, to control inflammatory eye disease, clinically suppress the inflammation and vasculitis, to prevent recurrences and thus, prevent irreversible damage. The choice of treatment is based on the severity of systemic involvement, clinical presentation and the site affected. The preferred treatment modalities are combined drug therapy and include topical therapies as well as systemic corticosteroids, NSAIDs, colchicine, dapsone and immunosuppressive and cytotoxic agents. Such therapies are tailored to the individual patient depending on clinical manifestations. Thalidomide, tacrolimus, IFN-alpha and anti-TNF monoclonal antibody have recently attracted attention as novel therapeutic approaches.

Abstract
Behçet disease is a multisystemic and chronic inflammatory disorder of unknown cause that is characterized by recurrent oral and genital ulcerations, ocular manifestations, and additional clinical manifestations in multiple organ systems. Behçet disease involving the chest can manifest as a wide spectrum of abnormalities. Although conventional chest radiography is commonly used for initial assessment, spiral computed tomography can demonstrate the entire spectrum of thoracic manifestations of Behçet disease, including abnormalities of the vessel lumen and wall, perivascular tissues, lung parenchyma, pleura, and mediastinal structures. Aneurysms of the pulmonary arteries, with or without thrombosis, are a typical manifestation of Behçet disease. Other manifestations include thrombosis, vasculitis, hemorrhage, infarction, and inflammation. Familiarity with these manifestations can be useful in the diagnosis of Behçet disease, helping to determine the cause of symptoms in patients who present with hemoptysis and guide the choice of appropriate therapy.

Abstract
BACKGROUND Behçet's disease is a multisystem disease featuring mucocutaneous, ocular, articular, vascular, intestinal, urogenital, and neurologic involvement and occurs with a high prevalence in the Mediterranean including Turkey. Higher incidence of severe clinical course and systemic involvement is observed in male patients. OBJECTIVE To determine the influence of sex on the clinical course of Behçet' s disease. METHODS We retrospectively evaluated the clinical findings of 2313 Behçet patients followed up at the multidisciplinary Behçet's Disease Center at Ankara University. RESULTS The male/female patient ratio was 1.03. Oral aphthae was seen in all patients. In male Behçet patients, the prevalence of mucocutaneous lesions and systemic manifestations was as follows: 85.6% genital aphthae, 45.5% erythema nodosum, 59.5% papulopustular lesions, 17.5% thrombophlebitis, 38.1% ocular involvement, 11.3% articular involvement, 11.7% vascular involvement, 3.3% neurologic involvement, 1.4% gastrointestinal involvement, and 1.8% pulmonary involvement. In female Behçet patients, the prevalence of manifestations were as follows: 91% genital aphthae, 49.8% erythema nodosum, 48.3% papulopustular lesions, 3.5% thrombophlebitis, 19.8% ocular involvement, 11.8% articular involvement, 2.1% vascular involvement, 1.3% neurologic involvement, 1.4% gastrointestinal involvement, and 0.03% pulmonary involvement. CONCLUSIONS Only genital aphthae and erythema nodosum were more frequent in females. On the other hand papulopustular eruptions, thrombophlebitis, ocular, neurologic, pulmonary and vascular involvement were more frequent in males. While female patients had the best prognosis, male patients had a worse overall prognosis than females.

Abstract
OBJECTIVE To present a case of pulmonary artery aneurysms (PAAs) in a child with Behcet's disease (BD). NATURE OF THE STUDY: Case report and review of the literature. MATERIALS AND METHODS The patient had a complete autopsy, drug screen and serological testing. A medical history was obtained and the literature was reviewed. RESULTS A 10-year-old African-American boy had massive hemoptysis while at home and died shortly thereafter in the emergency department of a local hospital. He had had two other episodes of hemoptysis in the past 2 months. At autopsy, he had bilateral inflammatory aneurysms of the lower lobe branches of the pulmonary arteries. The left aneurysm had eroded into the adjacent bronchus and accounted for the fatal hemoptysis. The right ventricle had endocardial fibrosis. Systemic vasculitis was absent. The child did not have oral, genital, eye or skin lesions at autopsy, or by clinical history. Based on the autopsy findings, a diagnosis of BD was made. CONCLUSIONS We present the very unusual case of a 10-year-old African-American boy who died from hemoptysis resulting from bilateral pulmonary aneurysms caused by BD.

Abstract
Pulmonary involvement in Behçet's disease (BD) is reported to indicate poor prognosis and high mortality. Our aim was to evaluate the pulmonary vascular status in BD. As 123I-meta-iodobenzylguanidine (123I-MIBG) shares the same uptake, storage and release mechanisms as norepinephrine, associated with the functional state of pulmonary endothelium, it may reflect endothelial injury. Twenty-five patients (13 males, 12 females; mean age, 36.44 years) and 12 age-matched controls were included. After intravenous injection of 123I-MIBG, thorax images were taken at 15 min and 4 h. Appropriate regions of interest were drawn, and heart to mediastinum (H/M) ratios and lung retention indices (LRI) were calculated. The difference between the LRI of controls (75.6+/-4%) and patients (87.7+/-10%) was found to be extremely significant (P<0.005). The LRIs of active (92.85+/-12%) and inactive (83.65+/-5%) states of BD were significantly different (P<0.05) from each other. There was no significant difference between the H/M ratios of controls (2.4+/-0.27) and patients (2.39+/-0.31) or between patients in active and inactive disease states. Our study revealed prolonged lung retention of 123I-MIBG in BD, probably reflecting the severity of the disease. In conclusion, 123I-MIBG lung retention is a valuable finding in the evaluation of pulmonary vascular status and may be a potential marker of prognosis in BD.
