- Embolização de Angiomiolipoma Renal ComplicadoPublication . Nobre, I; Fernandes, O; Garcia, V; Martins, JM; Pisco, JMApresenta-se um caso clínico de angiomiolipoma renal complicado por hemorragia, numa doente de 44 anos. Avalia-se o contributo diagnóstico e terapêutico da arteriografia, que neste caso permitiu uma apreciação rigorosa da vascularização das lesões e resolveu a situação hemorrágica através da embolização trans-catéter percutânea.
- HemangiopericitomaPublication . Nobre, I; Fernandes, O; Garcia, V; Manaças, J; Balcão Reis, J; Pisco, JMA propósito de um caso clínico de hemangiopericitoma com localização no membro inferior esquerdo, os autores fazem uma breve revisão desta entidade patológica. Destacam-se as suas principais características clínicas e salienta-se o contributo da arteriografia, no diagnóstico, e tratamento coadjuvante da cirurgia.
- Multimodality Imaging in Connective Tissue Disease-Related Interstitial Lung DiseasePublication . Ruano, C; Grafino, M; Borba, A; Pinheiro, S; Fernandes, O; Silva, S; Bilhim, T; Moraes-Fontes, MF; Irion, KInterstitial lung disease is a well-recognised manifestation and a major cause of morbidity and mortality in patients with connective tissue diseases. Interstitial lung disease may arise in the context of an established connective tissue disease or be the initial manifestation of an otherwise occult autoimmune disorder. Early detection and characterisation are paramount for adequate patient management and require a multidisciplinary approach, in which imaging plays a vital role. Computed tomography is currently the imaging method of choice; however, other imaging techniques have recently been investigated, namely ultrasound, magnetic resonance imaging, and positron-emission tomography, with promising results. The aim of this review is to describe the imaging findings of connective tissue disease-related interstitial lung disease and explain the role of each imaging technique in diagnosis and disease characterisation.

- Thoracic Manifestations of Connective Tissue DiseasesPublication . Ruano, C; Lucas, R; Leal, C; Lourenço, J; Pinheiro, S; Fernandes, O; Figueiredo, LConnective tissue diseases (CTDs) comprise several immunologic systemic disorders, each of which associated with a particular set of clinical manifestations and autoimmune profile. CTDs may cause numerous thoracic abnormalities, which vary in frequency and pattern according to the underlying disorder. The CTDs that most commonly involve the respiratory system are progressive systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis, Sjögren syndrome, polymyositis, dermatomyositis, and mixed connective tissue disease. Pulmonary abnormalities in this group of patients may result from CTD-related lung disease or treatment complications, namely drug toxicity and opportunistic infections. The most important thoracic manifestations of CTDs are interstitial lung disease and pulmonary arterial hypertension, with nonspecific interstitial pneumonia being the most common pattern of interstitial lung disease. High-resolution computed tomography is a valuable tool in the initial evaluation and follow-up of patients with CTDs. As such, general knowledge of the most common high-resolution computed tomographic features of CTD-related lung disease allows the radiologist to contribute to better patient management.
- A Utilização de Endopróteses na Síndrome da Veia Cava Superior por Neoplasia do PulmãoPublication . Pisco, JM; Nobre, I; Fernandes, O; Garcia, V; Martins, JM; Duarte, AC; Freitas, MGApresentam-se seis casos de síndrome da veia cava superior causado por neoplasia do pulmão e que foram tratados por endopróteses colocadas por via percutânea. Descreve-se a técnica e avaliam-se os resultados. Num caso ocorreu trombose aguda da endoprótese que foi tratada por uroquinase. Não se registaram outras complicações. Um doente faleceu 1 mês depois por progressão da doença. Os restantes mantinham-se sem queixas de síndrome da veia cava superior durante mais do que 6 meses. Conclui-se que a colocação de endopróteses é uma técnica pouco invasiva, eficaz e com melhoria imediata no síndrome da veia cava superior.
