- Acute segmental renal infarction due to factor V LeidenPublication . Cabral-Ribeiro, J; Sousa, L; Calaza, C; Santos, AOBJECTIVE: Renal infarction is rare and has variable clinical presentations causing diagnostic difficulties. Although most renal infarctions are caused by an obvious thromboembolic factor some are only explained by hereditary or acquired thrombophilia. The authors present a case of segmental renal infarction associated with factor V Leiden. METHODS/ RESULTS: A 48-year-old man presented with right flank pain that was unresponsive to analgesia for renal colic. CT scan was performed revealing a partial renal infarction. The etiologic study was only positive to factor V Leiden. In spite of the diagnosis and treatment it resulted in atrophy of the affected renal area. CONCLUSIONS: Renal infarction can be a presentation of thrombophilia that should be searched in the absence of an obvious embolic factor. Renal CT scan is the best way to a rapid diagnosis and treatment.

- Consensus Recommendations of the Multiple Sclerosis Study Group and Portuguese Neuroradiological Society for the Use of the Magnetic Resonance Imaging in Multiple Sclerosis in Clinical Practice: Part 1Publication . Abreu, P; Pedrosa, R; Sá, MJ; Cerqueira, J; Sousa, L; Da Silva, AM; Pinheiro, J; De Sá, J; Batista, S; Simões, RM; Pereira, DJ; Vilela, P; Vale, JINTRODUCTION: Magnetic resonance imaging is established as a recognizable tool in the diagnosis and monitoring of multiple sclerosis patients. In the present, among multiple sclerosis centers, there are different magnetic resonance imaging sequences and protocols used to study multiple sclerosis that may hamper the optimal use of magnetic resonance imaging in multiple sclerosis. In this context, the Group of Studies of Multiple Sclerosis and the Portuguese Society of Neuroradiology, after a joint discussion, appointed a committee of experts to create recommendations adapted to the national reality on the use of magnetic resonance imaging in multiple sclerosis. The purpose of this document is to publish the first Portuguese consensus recommendations on the use of magnetic resonance imaging in multiple sclerosis in clinical practice. MATERIAL AND METHODS: The Group of Studies of Multiple Sclerosis and the Portuguese Society of Neuroradiology, after discussion of the topic in national meetings and after a working group meeting held in Figueira da Foz on May 2017, have appointed a committee of experts that have developed by consensus several standard protocols on the use of magnetic resonance imaging in the diagnosis and follow-up of multiple sclerosis. The document obtained was based on the best scientific evidence and expert opinion. Subsequently, the majority of Portuguese multiple sclerosis consultants and departments of neuroradiology scrutinized and reviewed the consensus paper; comments and suggestions were considered. Technical magnetic resonance imaging protocols regarding diagnostic, monitoring and the recommended information to be included in the magnetic resonance imaging report will be published in a separate paper. RESULTS: We provide some practical guidelines to promote standardized strategies to be applied in the clinical practice setting of Portuguese healthcare professionals regarding the use of magnetic resonance imaging in multiple sclerosis. CONCLUSION: We hope that these first Portuguese magnetic resonance imaging guidelines, based in the best available clinical evidence and practices, will serve to optimize multiple sclerosis management and improve multiple sclerosis patient care across Portugal.

- Leiomioma da bexiga simulando neoplasia do úracoPublication . Cabral-Ribeiro, J; Sousa, L; Silva, C; Garcia, P; Mendes, V; Ribeiro dos Santos, AAs neoplasias de origem mesenquimatosa da bexiga são raras. Os leiomiomas representam a neoplasia mesenquimatosa benigna mais frequente da bexiga compreendendo de 0.2 a 0.5% de todos os tumores vesicais. A apresentação clínica é extremamente variável dependendo sobretudo da localização do tumor (intramural, extramural ou submucoso). Apresentamos um caso clínico de um leiomioma de localização ao nível da cúpula/superfície anterior de bexiga, de crescimento extramural que simulou neoformação do úraco.
