Hemoptisis como manifestación inicial de la enfermedad de Behçet: casos clínicos / Hemoptysis as the initial manifestation of Behçet's disease: report of two cases

Arterial involvement in Behçet's disease (BD) is less common than venous lesions. The most commonly affected arteries are: the aorta, lower extremity arteries, mesenteric, femoral, coronary, renal, subclavian and pulmonary arteries. The rupture of pulmonary arteries is the main cause of death of patients with EB and the presence of aneurysms is a bad prognostic factor. We report two patients with arterial involvement in BD. A 14 years old male presenting with hemoptysis lasting three days. A chest computed tomography showed an aneurismal dilatation of the right interlobar artery, bilateral intramural thrombi and alveolar hemorrhage. A right lobar pulmonary resection was performed but hemoptysis recurred. Suspecting a BD, prednisone was started and hemoptysis subsided. A 42 years old male presenting with chest pain and hemoptysis. A chest CT scan showed thrombi in pulmonary veins and anticoagulant therapy was started. Two months later he was admitted again due to a massive hemoptysis. The CT scan showed aneurisms in pulmonary arteries, mural thrombi and pulmonary infarction. With the diagnosis of BD, methylprednisolone, followed by prednisone and cyclophosphamide were used, with a good clinical response.

Comparison of optical coherence tomographic findings between Behcet disease patients with and without ocular involvement and healthy subjects / Comparação de achados de tomografia de coerência óptica em pacientes com doença de Behcet com e sem envolvimento ocular e indivíduos saudáveis

ABSTRACT Purpose: We aimed to compare the retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, and the choroid thickness between patients with Behcet disease and healthy subjects by using spectral domain optical coherence tomography (SD-OCT). Methods: Ninety eyes of 45 healthy subjects and 104 eyes of 52 patients with Behcet disease were included in this study. Rheumatoid factor and C-reactive protein levels were measured by blood testing in the patients. Results: The mean thickness of the retinal nerve fiber layer, ganglion cells layer, and inner plexiform layer were significantly lower in patients with Behcet's disease than in the healthy subjects. The mean choroidal thickness was significantly higher in the patients than in the healthy subjects. Conclusions: SD-OCT was a useful and non-invasive tool for the detection of retinal nerve degeneration and choroidal changes in patients with Behcet disease even in the absence of ocular involvement.

RESUMO Objetivo: Comparar a camada de fibras nervosas da retina, a camada de células ganglionares, a camada plexiforme interna e a espessura coróide entre os pacientes com doença de Behçet e indivíduos saudáveis usando tomografia de coerência óptica (OCT) de domínio espectral (SD). Métodos: Noventa olhos de 45 indivíduos saudáveis e 104 olhos de 52 pacientes com doença de Behcet foram incluídos no estudo. O fator reumatoide e os níveis de proteína C-reativa foram medidos por exames de sangue em pacientes com doença de Behcet. Resultados: As médias de espessura da camada de fibras nervosas da retina, da camada de células ganglionares e da camada plexiforme interna dos pacientes com Doença de Behcet foram significativamente menores do que o grupo controle. As medidas de espessura coróide média dos pacientes com doença de Behcet foram significativamente mais elevadas do que o grupo controle. Conclusões: Tomografia de coerência óptica é uma ferramenta útil e não invasiva para acompanhar a degeneração nervosa retiniana e as alterações coroidais em pacientes com doença de Behcet, mesmo sem envolvimento ocular.

Radiation Exposure from Abdominal Imaging Studies in Patients with Intestinal Behcet Disease

BACKGROUND/AIMS: Recently, several studies have revealed that diagnostic imaging can result in exposure to harmful levels of ionizing radiation in inflammatory bowel disease patients. However, the extent of radiation exposure in intestinal Behcet disease (BD) patients has not been documented. The aim of this study was to estimate the radiation exposure from abdominal imaging studies in intestinal BD patients. METHODS: Patients with a diagnosis of intestinal BD established between January 1990 and March 2012 were investigated at a single tertiary academic medical center. The cumulative effective dose (CED) was calculated retrospectively from standard tables and by counting the number of abdominal imaging studies performed. High exposure was defined as CED >50 mSv. RESULTS: In total, 270 patients were included in the study. The mean CED was 41.3 mSv, and 28.1% of patients were exposed to high levels of radiation. Computed tomography (CT) accounted for 81.7% of the total effective dose. In multivariate analyses, predictors of high radiation exposure were azathioprine/6-mercaptopurine use, surgery, and hospitalization. CONCLUSIONS: Approximately a quarter of intestinal BD patients were exposed to harmful levels of diagnostic radiation, mainly from CT examination. Clinicians should reduce the number of unnecessary CT examinations and consider low-dose CT profiles or alternative modalities such as magnetic resonance enterography.

Aneurisma volumoso da artéria pulmonar em paciente portador de doença de Behçet: relato de caso / Huge aneurism of the pulmonary artery in patient with Behçet's disease: case report

JUSTIFICATIVA E OBJETIVOS: A doença de Behçet caracteriza-se pela presença de lesões cutâneas, história de ulcerações orais, observação de patergia, envolvimento ocular do tipo uveíte e alterações vasculares. Constitui-se em afecção rara no nosso meio, inscrevendo-se no capítulo das vasculites sistêmicas primárias. RELATO DO CASO: Descrição de manifestação vascular pulmonar incomum, caracterizada pelo desenvolvimento de volumoso aneurisma na circulação arterial pulmonar em paciente com doença de Behçet. CONCLUSÃO: A presença de aneurisma da artéria pulmonar é manifestação rara, porém observada na doença em questão.(AU)

BACKGROUND AND OBJECTIVES: Behçet `s disease is a rare affection characterized by skin lesions, history of aftous ulcers, pathergy, ocular involvement like uveitis, as well as venous and arterial compromise. CASE REPORT: A patient with various systemic manifestations of Behçet’s disease, including a huge aneurysm in the left pulmonary artery. CONCLUSION: The appearance of this unusual vascular alteration is considered a rare manifestation of Behçet’s disease.(AU)

Imaging findings of neuro-Behcet disease

To study the neuroimaging findings of neuro-Behcet's disease [NBD] in Saudi patients and to discuss the radiological differential diagnosis. The clinical data and radiological findings on CT, MRI and cerebral angiography of 16 patients with NBD attending King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, from January 1990 to February 2003 were reviewed. Out of 16 patients with NBD, 11 patients [68.75%] had cerebral venous thrombosis predominantly involving superior sagittal sinus causing intracranial hypertension, while 5 patients [31.25%] had symptoms and signs related to brain parenchymal involvement predominantly affecting brainstem. Pattern of distribution of brain parenchymal lesions in NBD might help to differentiate it from other vasculitides as well as from demyelinating disease such as multiple sclerosis. Cerebral venous thrombosis is a common manifestation of NBD

Apport del'imagerie au diagnostic du neuro-behcet apropos de 5 cas

The authors report five patients with neuro- Behcet's disease. computed tomography showed low- density lesions with or without mass effect and contrast enhancement. Magnetic resonance imaging revealed scattered areas of high signal intensity on T 2- weighted images, and iso or low signal intensity on T1- weighted images with enhancement after gadolinium injection. These lesions affected all the central nervous system structures with predilection to the brain stem, basal brain ganglia, internal capsula, subcortical and deep cerebral white matter. By its availability, computed tomography remains a precious tool for diagnosis and assessment of severity of neurological involvement. Brain magnetic resonance imaging reveals silent lesions on CT, specifies their exact topography, identifies lesional association, reminiscent of neuro-Behcet and contributes to the differential diagnosis with multiple sclerosis. CT and MRI permit the follow- up of lesions under treatment and evaluate prognosis
