Aortitis with dissection complicating systemic lupus erythematosus

Non-infectious diseases of the aorta and large arteries

This article describes the various forms of inflammatory lesions of the aorta and large arteries, including chronic periaortitis, as well as the diagnostic methods are considered. Large vessel vasculitis represent the most common entities, however, there is also an association with other rheumatological or inflammatory diseases, drug-induced or paraneoplastic entities. Instrumental imaging modalities play an important role in the diagnosis.

Aortitis is an under-recognized manifestation of antiphospholipid syndrome: A case report and literature review

Aortitis is a classic manifestation of large vessel vasculitis. Antiphospholipid syndrome (APS), sometimes known as Hughes syndrome, is an acquired autoimmune disorder that manifests clinically as recurrent venous or arterial thrombosis. Patients with APS may also suffer from various underlying diseases, most frequently systemic lupus erythematosus (SLE). Catastrophic antiphospholipid syndrome (CAPS) is a rare but serious complication of APS characterized by failure of several organs due to diffuse microcirculatory thrombi. Its main manifestations involve the kidneys, lungs, heart and central nervous system, and require early diagnosis and rapid therapeutic management. While APS can affect virtually any blood vessel, aortitis is not a known symptom of APS. We report the case of a 36-year-old patient with APS and SLE who presented with CAPS during pregnancy, with no concomitant SLE flare. The first manifestation of CAPS was aortitis, preceding renal, cardiac and haematological manifestations. The outcome was favourable with combined treatment including corticosteroids, anticoagulants, plasma exchange and rituximab. We then carried out a literature search for papers describing the presence of aortitis in APS and/or SLE. In the cases of aortic involvement identified in the literature, including another case of CAPS, the occurrence of aortitis in SLE, often associated with the presence of antiphospholipid antibodies/APS, suggests that aortitis should be considered as an under-recognized manifestation and potential non-criterion feature of APS.

Idiopathic Aortitis With Retroperitoneal Fibrosis Course and Its Treatment

Aortitis is an inflammatory phenomenon involving one or more layers of the aorta and can have infectious or noninfectious etiologies. Complications of aortitis include aneurysm, dissection, and rupture, which can lead to ischemic organs and ultimately death. Noninfectious aortitis is often secondary to trauma or results from a systemic inflammatory process. It is further categorized based on clinical characteristics, laboratory findings, and imaging. There are some cases in which the etiology cannot be determined and is, therefore, idiopathic in nature. We present a case of a 67-year-old male who presented with malaise, abdominal pain, anorexia, and significant weight loss for several months. Imaging revealed retroperitoneal fibrosis and aortitis. After an extensive workup, we diagnosed idiopathic aortitis and treated the patient with high-dose corticosteroids that led to symptom improvement.

Lupus Aortitis Successfully Treated with Moderate-dose Glucocorticoids: A Case Report and Review of the Literature

Lupus aortitis is a rare and potentially life-threatening disorder. Previous studies have reported the utility of high-dose systemic glucocorticoids or surgery as the treatment, although there have been no related controlled trials. We herein report a 49-year-old woman with a 35-year history of systemic lupus erythematosus who was diagnosed with aortitis. Her symptoms and laboratory and imaging abnormalities rapidly resolved upon the administration of moderate-dose glucocorticoids. We subsequently performed a literature review of similar cases to identify the appropriate treatment and discuss these cases. A study of further cases will be needed to identify the characteristics of patients who would benefit from moderate-dose glucocorticoid therapy.

Rare Association of Antiphospholipid Antibody Syndrome, Systemic Lupus Erythematosus and Aortic Dissection: A Striking Presentation with Multi-Organ Failure?

Systemic lupus erythematosus is a chronic autoimmune disease with a wide variety of clinical presentations induced by different immunocomplexes and autoantibodies. Antiphospholipid antibody syndrome (APLAS) is a life-threatening clinical condition characterized by venous and arterial thromboses or pregnancy morbidity in the presence of persistent moderate/high levels of antiphospholipid antibodies. Aortic dissection is rarely associated with APLAS and always requires prompt diagnosis and early treatment. We report a rare case with a striking presentation. The patient developed multi-organ failure due to lethal aortic dissection and the obstruction of abdominal and thoracic branch vessels.

LEARNING POINTS

Aortic dissection is a rare lethal clinical condition that always requires prompt diagnosis and early treatment.Signs of multi-organ ischaemia due to obstruction of abdominal and thoracic branch vessels should be kept in mind by clinicians.Venous thrombosis and medial wall necrosis in the aorta may be underlying complex pathophysiological mechanisms in patients with antiphospholipid antibody syndrome.

Aneurysm of the ascending aorta in systemic lupus erythematosus: Case report and review of the literature

Cardiovascular manifestations in patients with systemic lupus erythematosus (SLE) are common, but aortic aneurysm formation is rare. We present a 63-year-old male SLE patient with a two-year history of skin lesions, leucopenia, pericarditis, mitral valve vegetations consistent with Liebman-Sacks endocarditis, and an aneurysm of the ascending aorta, which was successfully repaired surgically. Histologic examination of the aneurysm showed medial cystic degeneration, smooth muscle necrosis, and mild adventitial perivascular lymphocytic aggregates. This histology is typical of thoracic aneurysms that carry a high risk for aortic dissection and patient death. The case highlights the importance of early detection and treatment of thoracic aortic aneurysms in patients with SLE.

A case series of surgically diagnosed idiopathic aortitis in a Canadian centre: a retrospective study

BACKGROUND

Idiopathic aortitis became recognized relatively recently, and the body of knowledge concerning this condition is scarce. We aimed to determine the frequency of idiopathic aortitis in aortic specimens, the clinical, laboratory and radiologic characteristics at diagnosis and during follow-up, and the approach to investigation, treatment and monitoring taken by the treating physicians.

METHODS

We identified cases of aortitis diagnosed on pathological specimens of the aorta between Jan. 1, 2003, and July 31, 2013, at The Ottawa Hospital by reviewing the hospital's pathology database. Charts of identified patients were reviewed, and data on patient demographic characteristics, clinical features, laboratory and imaging tests, treatment and outcomes were analyzed.

RESULTS

A total of 684 aortic specimens were analyzed during the study period; 47 cases of aortitis were identified, 32 of which were idiopathic. Twenty-one patients (66%) had complete imaging of branch vessels at baseline, 16 (76%) of whom had additional aortic or branch vessel lesions. Twelve patients (38%) received corticosteroids postoperatively. Over a mean follow-up period of 47.5 months, among the 12 patients (38%) who had complete imaging of branch vessels at least once, new aortic or branch lesions were diagnosed in 5 (42%); 3/32 patients (9%) required additional vascular surgery; and a new systemic condition was diagnosed in 2/32 (6%).

INTERPRETATION

Idiopathic aortitis is commonly discovered incidentally on examination of the pathological specimen following ascending aortic aneurysm repair. No guidelines exist for the investigation, treatment and follow-up of this condition, resulting in great variability of practice. Good-quality prospective studies are needed to address the many unanswered clinical questions regarding idiopathic aortitis and to allow formulation of more definitive recommendations.

Anemia in a middle aged female with aortitis: a case report

Background

Idiopathic aortitis is among the most common causes of non-infectious aortitis, which rarely presents with anemia.

Case presentation

Here we report a case of a 49-year-old muhajir female who presented with shortness of breath and easy fatigability for the past 6 months. Physical examination revealed pallor and a diastolic murmur in the aortic region. Echocardiography showed thickened and calcified aortic and mitral valves, severe aortic regurgitation and dilatation of ascending aorta. She was advised aortic valve replacement and was referred to a haematologist due to concomitant anemia. Complete blood counts revealed haemoglobin: 7.7 gm/dl, mean corpuscular volume (MCV): 78 fl, mean corpuscular haemoglobin (MCH):23 pg, total white cell count: 9.0 × 10⁹/L and platelet count: 227 × 10⁹/L. Erythrocyte sedimentation rate (ESR) was 100 mm/hr. There was suspicion of myelodysplastic syndrome, but could not be confirmed as the patient refused bone marrow and cytogenetic studies. She was given erythropoietin, folic acid and ferrous sulphate. Following relatively prolonged therapy, her haemoglobin level increased to approximately 9.0 gm/dL. She was transfused with packed red cells and underwent aortic valve and ascending aorta replacement. The ascending aorta was dilated and aortic wall markedly thick and irregular. Histopathology of the resected aorta revealed granulomatous aortitis. She was prescribed prednisolone, which resulted in further incremental rise of haemoglobin to 13.1 gm/dL. One month later, she developed complaints of blurred vision in the right eye and was diagnosed with central retinal vein occlusion. She was treated with antiplatelet agents and her vision improved. After 3 months, she was asymptomatic and her haemoglobin level rose to 11.2 gm/dL without hematinic therapy or blood transfusion. She was begun on anticoagulant therapy and remains clinically stable.

Conclusion

We report a case of idiopathic aortitis with presumed diagnosis of anemia of chronic disease exhibiting a transient response towards steroid therapy post-valvuloplasty.

Consensus statement on surgical pathology of the aorta from the Society for Cardiovascular Pathology and the Association for European Cardiovascular Pathology: I. Inflammatory diseases

Inflammatory diseases of the aorta include routine atherosclerosis, aortitis, periaortitis, and atherosclerosis with excessive inflammatory responses, such as inflammatory atherosclerotic aneurysms. The nomenclature and histologic features of these disorders are reviewed and discussed. In addition, diagnostic criteria are provided to distinguish between these disorders in surgical pathology specimens. An initial classification scheme is provided for aortitis and periaortitis based on the pattern of the inflammatory infiltrate: granulomatous/giant cell pattern, lymphoplasmacytic pattern, mixed inflammatory pattern, and the suppurative pattern. These inflammatory patterns are discussed in relation to specific systemic diseases including giant cell arteritis, Takayasu arteritis, granulomatosis with polyangiitis (Wegener's), rheumatoid arthritis, sarcoidosis, ankylosing spondylitis, Cogan syndrome, Behçet's disease, relapsing polychondritis, syphilitic aortitis, and bacterial and fungal infections.

MDCT of acute conditions affecting the mesenteric vasculature

Acute conditions affecting the mesenteric vessels can cause abdominal pain and result in significant morbidity and mortality if not diagnosed and treated quickly. As bowel viability depends on patency of the mesenteric vessels, prompt diagnosis is essential. Helical multidetector computed tomography (MDCT) provides a rapid, widely available, non-invasive method to promptly evaluate the mesenteric arteries, veins, and abdominopelvic viscera. Given the value of MDCT in diagnosing vascular disease, it is important the radiologist understand technical and imaging findings of mesenteric vascular injury. Therefore, successful diagnosis hinges on familiarity with MDCT angiography and the extended capabilities of volume rendering and multiplanar reformation. In this review, we illustrate and describe key MDCT findings of congenital, inflammatory, traumatic, infectious, and thromboembolic conditions affecting the mesenteric vasculature in adult patients.

Lethal manifestations of systemic lupus erythematosus in a forensic context

Systemic lupus erythematosus is an autoimmune connective tissue disorder that affects multiple organs. While the clinical manifestations may vary in intensity over time and be associated with chronic disease, occasional cases occur where sudden and unexpected death has occurred. Cardiovascular disease is common, with accelerated atherosclerosis, intravascular thrombosis associated with antiphospholipid syndrome, and hypertensive cardiomegaly. Vasculitis with superimposed thrombosis may result in critical reduction in blood to vital organs, such as the heart and brain with infarction. Mesenteric ischemia may be caused by vasculitis, thrombosis, and accelerated atherosclerosis and may result in lethal intestinal infarction. Other diverse causes of sudden death include myocarditis, epilepsy, pulmonary hypertension, pulmonary thromboembolism, and sepsis. The autopsy evaluation of such cases requires careful examination of all organs with extensive histological sampling to include blood vessels, and microbiological sampling for bacteria, viruses, and fungi.

Isolated thoracic aortitis: clinicopathological and immunohistochemical study of 11 cases

Isolated thoracic aortitis (ITA) is diagnosed in a variable proportion of patients operated on for dilation/aneurysm of ascending aorta. The etiopathogenesis of ITA remains unclear. We studied 11 cases of ITA in order to determine the role of IgG4-mediated immune responses in its pathogenesis. The series included nine women and two men aged 52-79 years. All patients developed aortic incompetence due to dilation/aneurysm of ascending aorta. None of the patients had a history of IgG4-related disease neither did they develop features of such disease during the follow-up period. The microscopic findings included the presence of lymphoplasmacellular fibrosing infiltrate of varied intensity involving the adventitia and media of aorta. This inflammation was associated with severe medial elastic fiber defects. Obliterative phlebitis of the vasa vasorum was absent. Immunohistochemically, the inflammatory infiltrate comprised T- and B-lymphocytes as well as plasma cells. The plasma cell population was polyclonal with a predominance of IgG-producing cells. In all the cases, IgG4-producing plasma cells were detected. In five cases, the count exceeded 20 cells per high-power field. The IgG4/IgG ratio ranged from 0.07 to 0.98 (median 0.55). In six cases with the ratio >0.50, severe adventitial fibrosis was present. To the best of our knowledge, ours is the first study focused on investigating the role of IgG4-positive plasma cells in the development of ITA. Our results suggest that a subset of ITA may represent aortic manifestation of IgG4-related disease. Further research is necessary in order to clarify this issue.

Aortic dissection complicated with hemothorax in an adolescent patient with systemic lupus erythematosus: case report and review of literature

OBJECTIVES

To report a young patient with systemic lupus erythematosus (SLE) complicated by aortic dissection. The relevant literature on the association of SLE and aortic dissection is reviewed.

METHODS

We describe an adolescent patient with childhood-onset SLE diagnosed aortic dissection with presentation of hemothorax. The literature review was performed by a PubMed search using the keywords systemic lupus erythematosus (SLE), aortic dissection, hemothorax, and carotid intima-media thickness (CIMT).

RESULTS

A 17-year-old male was admitted to the hospital for severe abdominal pain. His past medical history included childhood-onset SLE complicated with lupus nephritis. Acute aortic dissection complicated with hemothorax was diagnosed and he died despite medical therapy. The accelerated CIMT progression of our patient, 0.14 mm in 20 months, might suggest ongoing premature atherosclerotic changes in the aortic wall. On reviewing the English literature, 21 cases of aortic dissection in SLE have been analyzed and discussed. Patients younger than 40 years of age, hypertension, and long-term steroid use are common features of aortic dissection in SLE patients. The possible pathogenesis of aortic dissection in SLE includes atherosclerosis, degeneration, and vasculitis. The widely accepted CIMT measured by ultrasound could be a potential diagnostic tool to access the risk of cardiovascular events.

CONCLUSIONS

Aortic dissection is a rare complication of SLE, but could take place in an adolescent patient with childhood-onset disease. It is important to include aortic dissection as a differential diagnosis in SLE patients with unexplained sharp abdominal, chest, or back pain.

Aortitis

Inflammatory or noninfectious aortitis may be idiopathic or it may be part of a systemic autoimmune disease, such as Takayasu's arteritis, Behçet's disease, or giant cell arteritis. At the acute stage, there is thickening of the aortic wall with dilatation of the aorta, more commonly in the thoracic aorta. If it involves the aortic root, there may be annuloaortic ectasia or aortic regurgitation. At a later stage, there may be aneurysmal dilatation of the aorta and rarely dissection or rupture of the aorta. In Takayasu's arteritis, stenosing lesions can occur as well as aneurysmal dilatation of the aorta or arteries. Stenosing lesions may be treated with angioplasty with or without stenting, whereas aneurysmal dilatation of the aorta is treated by aneurys-mectomy with arterial reconstruction or conduit. Severe aortic regurgitation may require aortic valve surgery with or without replacement of the ascending aorta. Irrespective of the interventional procedure undertaken as appropriate for the lesion, control of inflammation with steroid therapy with or without other immunosuppressive agents is of paramount importance. Otherwise, prosthetic valve or graft dehiscence may occur after aortic surgery, and restenosis rate is also higher after percutaneous transluminal angioplasty or stenting.

Aortitis and aortic thrombus in systemic lupus erythematosus

Aortitis is an uncommon complication of systemic lupus erythematosus (SLE). Most cases of lupus-associated aortitis have been described in conjunction with aortic aneurysms or aortic dissection and have been documented either at autopsy or during surgery to repair a dissection. We describe an unusual case of aortitis associated with an aortic thrombus in a young man with SLE.

Dissection of the temporal artery in a patient with giant cell arteritis

A 74-year-old woman presented to her rheumatologist with classic symptoms of giant cell arteritis. The temporal arteries were strikingly swollen, warm, and erythematous. On biopsy of the right temporal artery, a focal dissection was found associated with a pan-arteritis and giant cells. Isolated temporal artery dissection in giant cell arteritis has not been reported previously. We propose that the unusually intense vascular inflammation may have weakened the vessel wall, so that the dissection occurred during the routine physical exam or biopsy. We believe this case illustrates that physicians should take special care in the examination of floridly inflamed vessels, because vigorous palpation might lead to dissection. In the case of patients with giant cell arteritis, dissection may result in an increased risk of ischemic complications, such as scalp necrosis.

Limited Dissection of Abdominal Aortic Aneurysm in a Patient with Multiple Myeloma

Dissection limited to the abdominal aorta contributes 4% of all aortic dissections, and inflammatory injury of the aortic media is one of factors associated with dissection. In multiple myeloma, leukocytoclastic vasculitis of the skin has been known. We describe limited dissection of an abdominal aortic aneurysm with dense lymphocyte infiltration in a 62-year-old man with multiple myeloma. Although it is unclear whether the lymphocyte infiltration in the aortic wall, which was denser than that of atherosclerotic aneurysm, was associated with multiple myeloma, the excessive aortic wall inflammation may have somewhat influenced aneurysm formation or aortic dissection.

Les aortites inflammatoires

PRINCIPLE AND OTHER CAUSES: Takayasu's arteritis, giant cell arteritis and Behçet's disease are the three main causes of inflammatory aortitis. More rarely, aortitis can be observed in Cogan's syndrome, atrophic polychondritis, sarcoidosis, ankylosing spondylitis and in rheumatoid arthritis. RISKS OF PROGRESSION: Takayasu's arteritis is distinct with the development of stenotic lesions of the aorta. With the other causes, aortitis can be complicated by ectasia or even aneurysm, with the risk of rupture. Indeed, during giant cell arteritis, patients are 17 times more likely to develop thoracic aortic aneurysm. Aortic regurgitation is a frequent complication of inflammatory aortitis. Sometimes, aortitis is only manifested by general signs such as fever or an inflammatory syndrome. SUPPLEMENTARY EXPLORATIONS: Recent advances in diagnosis and follow-up of patients with inflammatory aortitis concern the use of non-invasive imaging techniques: Doppler ultrasonography, computed tomography with injection of a contrast product and magnetic resonance imaging, which currently replace the aortography.

DIAGNOSTIC PROBLEMS

Infectious aortitis, inflammatory atheromatous aneurysm and retroperitoneal fibrosis are sometimes misleading differential diagnoses.

Large vessel involvement in ANCA-associated vasculitides: report of a case and review of the literature

Vasculitides are currently classified according to the size of the vessels involved and characteristic clinical and histopathologic findings. Antineutrophil cytoplasmic antibodies (ANCA) and other serologic tests have been used to further characterize small vessel vasculitides. Large vessel involvement in ANCA-associated small vessel vasculitides has been overlooked in the medical literature. Here, we report a case of fatal aortitis and aortic dissection in a patient with microscopic polyangiitis and review reported cases of large vessel involvement in ANCA-associated vasculitides since 1990. We have attempted to characterize this subgroup of patients. Large vessel disease in ANCA-associated vasculitis may present as stenosing large vessel arteritis, aneurysmal disease, aortic dissection, aortic rupture, aortic regurgitation, and death. Prominent perivascular inflammation may present as mediastinal, cervical or abdominal soft tissue masses. ANCA-associated large vessel disease should be considered in the differential diagnosis of these disorders. The epidemiologic, clinical and pathologic characteristics of these patients differ from those of the well-defined large vessel vasculitides such as giant cell (temporal) arteritis or Takayasu's arteritis. We suggest that large vessel involvement is part of the spectrum of ANCA-associated vasculitis rather than an overlap with other large vessel vasculitides. It occurs in both myeloperoxidase- and proteinase 3-positive patients with either Wegener's granulomatosis or microscopic polyangiitis, but has not been reported in Churg-Strauss syndrome. Large vessel vasculitis can precede small vessel vasculitis or occur in the absence of small vessel involvement. We hope this report will contribute to the ongoing development of classification systems for the vasculitic syndromes.

Acute type A aortic dissection in a patient with systemic lupus erythematosus

The case of a 27-year-old Japanese woman with type A acute aortic dissection who had been diagnosed with systemic lupus erythematosus (SLE) is presented. The patient also had aortic regurgitation due to non-infective endocarditis and systemic hypertension, and had been maintained on steroid therapy for 15 years. Her twin sister was also diagnosed with SLE. The patient was admitted to emergency due to severe back pain. A chest x-ray showed enlargement of the upper mediastinum. Echocardiography revealed a thickened and deformed aortic valve with aortic regurgitation and dissection of the ascending aorta, but pericardial effusion was not found. Computed tomography demonstrated aortic dissection extending from the ascending aorta to the abdominal aorta. Graft replacement of the ascending aorta and proximal aortic arch was performed under hypothermic circulatory arrest with retrograde cerebral perfusion. The patient recovered uneventfully. Aortic dissection complicated with SLE is extremely rare, and this is only the 15th case reported in the English or Japanese literature.

Nondissecting aneurysm of the thoracic aorta with arteritis in systemic lupus erythematosus

A nondissecting aneurysm of the distal descending thoracic aorta, 55 mm in diameter, in a 35-year-old woman who was undergoing 24-year steroid therapy of systemic lupus erythematosus was successfully resected and replaced with a tube graft. The suture line of the aortic wall was reinforced with a polytetrafluoroethylene felt strip. Histologically, the media and adventitia contained numerous lymphoplasmacytic infiltrates that consisted of B and activated T cells mixed with plasmacytes. These findings would have been in accordance with active aortitis. Systemic lupus erythematosus was suggested as possibly associated with nondissecting thoracic aortic aneurysm, especially in patients undergoing chronic steroid therapy in which inflammation continued.

Ten years' experience of aortic aneurysm associated with systemic lupus erythematosus

BACKGROUND

aortic aneurysm is a rare but life-threatening cardiovascular complication in patients with systemic lupus erythematosus (SLE). The purpose of this study was to clarify the characteristic clinical features and the pathological mechanism of aneurysmal formation in these patients.

METHODS

among 429 patients operated on for abdominal aortic aneurysm (AAA) during the past 10 years, five cases with SLE were treated surgically. Their clinical data were reviewed, and the resected aneurysmal wall of the five patients was also examined histologically.

RESULTS

the mean age of the patients with SLE was 55 years, which was statistically younger than that of the other patients (mean 77 years, s.d. 7.9, p <0.05). They had received long-term corticosteroid therapy for the treatment of SLE for a mean of 23 years. Histologically, destruction of the medial elastic lamina was characteristic. Four patients had no complications in the postoperative follow-up period (mean 4 years), while the remaining patient died of rupture of a dissecting aneurysm two years after operation.

CONCLUSION

prolonged steroid therapy may play a major role in accelerating atherosclerosis, which can result in aortic aneurysmal enlargement, possibly together with primary aortic wall involvement and/or vasculitic damage in patients with SLE.

Stanford type A aortic dissection in a hypertensive patient with atherosclerosis of aorta and aortitis

Dissection of aorta is a serious condition; the main factors are hypertension and diseases of the connective tissue or of collagen. Aortitis syndrome in combination with hypertension and atherosclerosis in association with ascending aortic dissection is rarely seen. We present the case of a 53-year-old hypertensive patient whose ascending aortic dissection was associated with pericardial effusion without rupture of the aorta and with pleural effusion. Several unusual aspects of transesophageal echocardiography are described. The intraoperative biopsy revealed inflammatory aortitis with mural hematoma, without giant cells. The literature concerning aortic dissection and aortitis is reviewed.

Takayasu's aortitis with dissection in systemic lupus erythematosus

A forty-seven-year-old Japanese woman under treatment for systemic lupus erythematosus (SLE), complained of severe back pain. Chest X-ray and MRI showed an aneurysmal dilatation of the ascending aorta. Subsequently an aortic replacement was performed. Microscopically, the resected aorta showed Takayasu's aortitis with chronic dissection. Both aortitis and dissection are rare events in SLE patients. To our knowledge, this is the first report of Takayasu's aortitis with dissection in a patient with SLE.

Vertebrobasilar artery territory infarction as an initial manifestation of systemic lupus erythematosus

Cerebral infarction is a well-documented complication of systemic lupus erythematosus (SLE), that usually occurs several years after the diagnosis of SLE. To our knowledge, however, strokes associated with vertebrobasilar artery involvement were not reported to present as an initial manifestation of SLE. We report two patients, who presented with vertebrobasilar territory infarction as an initial manifestation of SLE. Patient 1 was a 16-year-old girl, who developed dysarthria and ataxia. MRI showed multiple infarcts in the pons, cerebellum and thalamus. Four-vessel cerebral angiography showed multifocal stenoses in the vertebral and basilar arteries with beaded appearance. Patient 2 was a 26-year-old woman, who developed headache associated with dysarthria, dizziness and ataxia. MRI showed multiple infarcts in the cerebellum, medulla, pons, midbrain and thalamus. Cerebral angiography revealed occlusion of both vertebral arteries at the first cervical vertebral level with non-visualization of the basilar artery. Both patients were diagnosed as having SLE supported by laboratory results. Although rare, posterior circulation stroke can present as an initial manifestation of SLE, which may be attributed to vasculitis or dissection in the vertebral/basilar artery.

Aortic dissection in a young corticosteroid-treated patient with systemic lupus erythematosus--a case report

We report a rare case of acute aortic dissection in a young, corticosteroid-treated hypertensive patient with a long-standing history of systemic lupus erythematosus (SLE). A brief review of literature on aortic dissection in lupus erythematosus is presented. A low threshold for performing transesophageal echocardiography in the management of chest pain syndrome in SLE is emphasized.

Atypical manifestations in a patient with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic systemic inflammatory disease associated with the production of various autoantibodies and involvement of multiple organs. Necropsy findings in a 65 year old woman with SLE who had multiple aortic aneurysms and dissections, as well as other unusual manifestations, are described. The case illustrates the occurrence of and the difficulties encountered in the diagnosis of several diseases, namely aortic aneurysm, aortic dissection, acute pancreatitis, and Penicillium marneffei infection.
