Aneurysmal bone cysts are vascular benign fibroblastic lesions usually found in bone that are locally destructive, with a greater incidence in the first and second decades of life. Patients usually undergo curettage or, less frequently, surgical resection, which may lead to growth disturbances and deformities in cases of large or complex lesions. Minimally invasive techniques such as sclerotherapy and endovascu...
Objective: The link between the systemic vasculature system and tumor biology is here investigated by studying the contribution of CβS (844ins68), MTHFR (677C > T), NOS3 (4a/4b), CYBA (C242T), and ACE1 (I/D) genes to leiomyoma onset, uterus and leiomyoma volumes. Methods: DNA samples from 130 women with leiomyomas and 527 from healthy women were genotyped by PCR or PCR-RFLP. Qui-square (χ2) or Fisher's exact te...
Os principais desafios ao ensino de anatomia e radiologia no mestrado integrado de medicina (MIM) prendem-se com o tempo limitado e o enorme volume de informação. Para fazer face as estas limitações, as reformas do MIM levaram a que o ensino de anatomia e radiologia fosse fundido em muitas faculdades de medicina. Na NOVA medical school, o ensino de anatomia clínica e radiológica foi estruturado numa unidade cur...
O hiper-aldosterolismo primário é a causa mais comum de hipertensão secundária. Quando originado por patologia unilateral, pode ser tratado curativamente por adrenalectomia. O doseamento hormonal por cateterismo das veias supra-renais (VSRs) é essencial para discriminar entre patologia uni versus bilateral. O conhecimento da anatomia normal e variantes das VSRs é importante para evitar falsos negativos e aument...
A Acta Radiológica Portuguesa é o principal veículo de divulgação científica da SPRMN. Com trinta e quatro anos de existência apresenta sinais de jovialidade com mais de trinta trabalhos ativos sob processo de revisão por pares. Representa a voz científica da comunidade radiológica nacional e internacional, que se quer cada vez mais participativa em quantidade e qualidade. Os tempos actuais são pautados por uma...
Introduction: Primary aldosteronism is the most common cause of secondary hypertension. Adrenal vein sampling is the gold standard for subtyping primary aldosteronism. However, this procedure is technically challenging and often has a low success rate. Our center is one of the very few performing this technique in our country with an increasing experience. Objective: This study aimed to evaluate the role of the...
A Acta Radiológica é a voz científica dos Radiologistas Portugueses e das Sociedades e Associações Radiológicas nacionais. Damos as boas vindas a comunicações curtas, editoriais e perspectivas de todos os leitores que possam estar interessados.

Purpose: Assess long-term outcomes of prostatic artery embolization (PAE) for patients with benign prostatic hyperplasia (BPH). Materials and methods: Single centre retrospective study from 2009-2019 including 1072 patients who received PAE and had available follow-up. Patients were evaluated yearly at 1-10 years post PAE using the International Prostate Symptom Score (IPSS) and quality of life (QoL), prostate ...
Inflammatory myofibroblastic tumour is a rare entity of indeterminate biological potential with a reduced tendency for recurrence and metastasis. Although it can arise from multiple organs, the bile duct is a very rare site of origin. We report the case of a 75-year-old asymptomatic male with elevated gamma-glutamyl transferase [1575 U/L (12 - 64 U/L)] and alkaline phosphatase [271 U/L (40 - 150 U/L)]. Computed...
and leukopenia) and monoclonal gammopathy (IgG lambda) not fully clarified presents with portal hypertension and splenomegaly of unclear cause. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) were performed for further investigation.
