Behçet’s disease associated with superior vena cava syndrome without thrombosis

Diffuse generalized venulitis as the primary pathology of Behçet's disease: A comprehensive magnetic resonance venography study

OBJECTIVE

Behçet's Disease (BD) is a chronic multisystem vasculitis that manifests with destructive inflammation affecting the eyes, central nervous system, and blood vessels. The pathology of vein involvement in BD is poorly characterized. Magnetic resonance (MR) venography gives more comprehensive information about deep veins and adjacent tissues. In this study, we aimed to characterize vein involvement and evaluate the diagnostic utility of MR venography in BD.

METHODS

Sixty-five BD patients who fulfilled the International Study Group (ISG) criteria and 20 healthy control subjects were enrolled. Inferior vena cava (IVC), common iliac veins (CIV), external (EIV) and internal iliac veins (IVV), common femoral veins (CFV), femoral veins (FV), and greater saphenous veins (GSV) of BD patients and healthy controls were evaluated with MR venography and ultrasonography for the presence pathologic features, luminal thrombi, vessel wall changes, and perivascular abnormalities.

RESULTS

33 vascular and 32 non-vascular BD patients (mean age 39.3 ± 11.3 years and 48 [73.8%] male) were enrolled. MR venography revealed diffuse concentric thickening of the walls of IVC, CIV, EIV, IIV, CFV, FV, and GSV in BD (healthy controls vs. BD p<0.05 for all vein segments). MR venography provided additional information about veins and perivascular tissues like contrast enhancement, enlarged lymph nodes, and seminal vesicle vascularization, which were remarkably more frequent in vascular BD than non-vascular BD and healthy controls.

CONCLUSION

The results of our study suggest that the involvement of the venous system is diffuse and generalized in BD, and demonstration of venulitis might help diagnose the disease.

Behçet's Disease: A Radiological Review of Vascular and Parenchymal Pulmonary Involvement

Behcet's disease (BD) is a chronic systemic inflammatory disorder characterized by underlying chronic vasculitis of both large- and small-caliber vessels. Thoracic involvement in BD can occur with various types of manifestations, which can be detected with contrast-enhanced MSCT scanning. In addition, MR can be useful in diagnosis. Characteristic features are aneurysms of the pulmonary arteries that can cause severe hemoptysis and SVC thrombosis that manifests as SVC syndrome. Other manifestations are aortic and bronchial artery aneurysms, alveolar hemorrhage, pulmonary infarction, and rarely pleural effusion. Achieving the right diagnosis of these manifestations is important for setting the correct therapy and improving the patient's outcome.

A Case of Systemic Lupus Erythematosus without Antiphospholipid Syndrome Causing Superior Vena Cava Syndrome

Systemic lupus erythematosus (SLE) is an autoimmune disease with multisystem involvement. Superior vena cava (SVC) syndrome is mainly caused by malignant tumors such as lung carcinoma, lymphoma, and metastatic tumors. We report a 20-year-old woman who was admitted with features of SVC syndrome secondary to SVC thrombus. Further evaluation confirmed the diagnosis of SLE without associated antiphospholipid syndrome (APS). The patient was treated with heparin with oral anticoagulant, steroids, and hydroxychloroquine. Complete resolution of thrombus was documented within a few weeks. SVC thrombosis as an initial presenting feature of SLE without associated APS has not been reported so far in the literature.

Thoracic Complications in Behçet's Disease: Imaging Findings

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.

Imaging manifestations of Behcet's disease: Key considerations and major features

Behcet's disease is an autoimmune disease most commonly seen in the Middle East. Although primarily known with painful oral and genital ulcers, it can lead to vasculitis. Therefore, several associated complications such as thrombotic syndromes, aneurysmal arterial disease may arise. In many cases, it might be difficult to make the diagnosis purely based on clinical grounds; however, imaging plays an important role for both diagnosis and assessment of the disease's complications. We provide a comprehensive review of the most notable imaging findings of Behcet's disease.

Major vessel involvement in Behçet's disease: an update

PURPOSE OF REVIEW

Large vessel vasculitis occurs in a subgroup of patients with Behçet's disease who are at high risk for disease-related morbidity and mortality. Recognition of patients at risk, early detection of vasculitis, and aggressive treatment are essential for optimal care of these patients. We review the expanding knowledge on large vessel problems in Behçet's disease, highlighting recent contributions.

RECENT FINDINGS

Vasculo-Behçet patients are at risk for multiple vessel-related complications including thromboses, stenoses, occlusions, and aneurysms. The primary reason for clot seems to be an inflammatory process in the vessel wall. Less invasive endovascular procedures are increasingly used to treat aneurysms in Behçet patients.

SUMMARY

Because of earlier recognition, aggressive medical treatment, and novel surgical procedures, the morbidity and mortality of large vessel vasculitis in Behçet's disease are improving.

Dermatological features in Behçet disease-associated vena cava obstruction

BACKGROUND

Behçet disease (BD) is a multisystemic disorder that is classified as vasculitis and can affect all types and sizes of blood vessels. Although vascular diseases are not regarded as essential for a diagnosis of BD, vascular complications can be fatal.

OBJECTIVES

The purpose of this study was to examine the clinical characteristics of 14 patients with BD accompanied by an obstruction of the superior vena cava (VC), the inferior VC, or both, and then determine the dermatological features that indirectly suggest VC obstructions in patients with BD.

METHODS

Among the 3500 patients registered at the BD Specialty Clinic of Severance Hospital from 1997 to 2006, 14 patients were diagnosed with BD-associated VC obstructions. Their medical records were reviewed.

RESULTS

Nine of the 14 patients with BD were male, and the age range for disease onset was 11-46 years. Computed tomography revealed superior VC thrombosis in seven patients, inferior VC thrombosis in four patients, and the involvement of both in three patients. The most prominent features in superior VC obstruction were facial oedema (n = 7, 50%) and neck vein distension (n = 6, 43%). Other features included dilated veins in the chest wall, upper body oedema, proptosis, and upper extremity swelling. Patients with an inferior VC obstruction commonly had dilated veins on the abdominal walls. These patients also had abdominal distension and lower extremity swelling. Corticosteroids, colchicine, immunosuppressants, and anticoagulants with or without heparinization were the most common treatment regimens giving good response. Attempts to treat patients with a high dose of steroid pulse therapy were ineffective. Ballooning venoplasty was a useful therapeutic modality for VC thrombosis during the early stage, although this procedure could not be performed in patients with BD with severe thrombosis.

CONCLUSIONS

Several cutaneous features of VC obstruction should be recognized in patients with BD. Early detection might permit an early diagnosis and treatment of occlusion of the VC.

Superior vena cava syndrome without thrombosis revealing Behçet's disease: Two cases

Superior vena cava (SVC) thrombosis is a rare but well-recognized manifestation of Behcet's disease, whereas SVC syndrome due to vasculopathy, without evidence of thrombosis, has only been described a single time in the literature. We report two cases of this exceptional association. The two patients presented with swelling of the face and oral aphtosis, the SVC stenosis was evidenced by angio-CT and classical cavography. In each case, a combination of anticoagulant and immunosuppressive (corticosteroids and azathioprine) treatments allowed a significant improvement of SVC diameter. In one of the patients, an angioplasty of SVC was also performed. We believe there is a continuum between non-obstructive and obstructive vasculopathy (thrombosis) of SVC. Inflammatory vascular injury secondary to vasculitis is considered to be the primary reason for thrombosis in Behcet's disease. Thickening of the venous wall observed in our patients probably reflects this inflammatory vascular injury. In conclusion, Behcet's disease should be considered in the differential diagnosis of SVC syndrome not related to thrombosis.
