  1. Delayed onset diplopia associated with a stab wound dural cerebrospinal fluid fistula

    Ginestal, R; García-Moreno, E; Marques, J; Simões, R; Serafim, A; Palma, T
    A paresia do motor ocular externo é a neuropatia intracraniana secundária à síndrome de hipotensão intracraniana mais frequentemente descrita (habitualmente espontânea ou iatrogénica, especialmente depois de punção lombar ou de anestesia epidural). Mesmo assim, trata-se duma complicação pouco frequentemente descrita na literatura. As lesões por facadas na medula espinhal são relativamente infrequentes, embora ainda mais infrequente é a sua apresentação clínica de forma atrasada. Apresentamos o caso de um homem de 31 anos de idade que começou com diplopia 6 dias depois de ser esfaqueado na região lombar. Este caso clínico mostra a necessidade duma avaliação precoce e eficaz da...

  2. Isolated Visceral Angioedema Induced by Angiotensin-Converting Enzyme Inhibitor

    Oliveira, AM; Santiago, I; Carvalho, R; Martins, A; Reis, J
    Visceral angioedema is a rare complication of therapy with angiotensin-converting enzyme (ACE) inhibitors. Clinical presentation includes nausea, vomiting, abdominal pain and diarrhea. Early detection of this entity can prevent recurrent episodes and unnecessary invasive procedures, including surgery. This article describes a 46-year-old-woman who presented to the emergency department with abdominal pain, associated with nausea and vomiting. She had been taking ramipril for 15 days. A computed tomography was performed which revealed thickening of a jejunal segment, with submucosal edema. ACE inhibitor-associated angioedema was suspected and the medication was discontinued, with resolution of symptoms in 48 h. After 7 months of follow-up, the patient is asymptomatic. Despite of its rarity, ACE inhibitor-induced...

  3. Doença inflamatória pélvica: o que o radiologista precisa saber?

    Abreu, E; Rosado, E; Cunha, TM
    O diagnóstico da doença inflamatória pélvica é clínico, baseando-se numa combinação de sintomas e sinais, que incluem dor pélvica e febre. A referenciação ao médico radiologista ocorre na fase aguda da doença, quando é necessário excluir diagnósticos diferenciais (ginecológicos, gastrointestinais ou urinários) ou em doentes que tiveram um episódio agudo prévio, por vezes assintomático, que recorrem ao médico assistente por complicações, como dor pélvica crónica, gravidez ectópica e infertilidade. Neste contexto, é fundamental que o médico radiologista reconheça as manifestações radiológicas dos diferentes estádios da doença inflamatória pélvica, com especial ênfase para o abcesso tuboovárico, cujas características radiológicas colocam diagnóstico diferencial com carcinoma do ovário.

  4. Pitfalls em radiologia ginecológica

    Rosado, E; Cunha, TM
    Para o diagnóstico radiológico das patologias ginecológicas é essencial conhecer e compreender as indicações dos vários exames disponíveis e, para cada achado radiológico, integrar a idade, o contexto clínico e a história pregressa da doente. A Ressonância Magnética (RM) tem hoje um papel crucial no diagnóstico das doenças ginecológicas. Contudo, para maximizar o potencial desta técnica é imprescindível adequar o protocolo utilizado a cada caso e a cada doente e ter em conta algumas regras imprescindíveis à interpretação dos exames, que descreveremos neste artigo. A RM ginecológica é principalmente útil no estadiamento do carcinoma do colo do útero e do endométrio, podendo por vezes ser também útil na sua detecção, na avaliação da resposta ao tratamento, detecção...

  6. Two-dimensional visualization and measurement of the fetal optic chiasm: improving counseling for antenatal diagnosis of agenesis of the septum pellucidum.

    Viñals, F; Ruiz, P; Corre, F; Pereira, P
    OBJECTIVE: To develop an objective method for visualizing and measuring the fetal optic chiasm (OC) using transvaginal two-dimensional (2D) ultrasound in the coronal plane and to report measurements in fetuses with agenesis of the septum pellucidum (SP). METHODS: This was a prospective cross-sectional study of 115 morphologically normal fetuses in low-risk pregnancies, between 21 and 30 weeks' gestation. The OC was measured in a coronal plane at the level of the third ventricle and was seen as a horizontally aligned dumbbell-shaped structure of moderate echogenicity. In addition, OC measurements from eight fetuses with agenesis of the SP and complete follow-up were compared with...

  7. Off-Label Use of Ultrasound Contrast Agents for Intravenous Applications in Children: Analysis of the Existing Literature

    Rosado, E; Riccabona, M
    OBJECTIVES: The purpose of this study was to collect and analyze the published data related to intravenous (IV) use of ultrasound (US) contrast agents in children. METHODS: We searched the literature to collect all of the published studies reporting the IV administration of a second-generation US contrast agent in children. RESULTS: We analyzed 9 case series and 5 case reports, as well as 5 individual cases, of pediatric contrast-enhanced US use reported in a study group that also included adults. We found that 502 children underwent contrast-enhanced US examinations (mean age, 9.7 years; range, 1 day-18 years). Most patients (89%) were injected with the sulfur...

  10. Disección de la arteria vertebral asociada a síndrome MURCS

    Santos, M; Cruz, S; Casimiro, C; Biscoito, M; Costa, M
    La asociación MURCS (OMIM 60176), también conocida como síndrome de Mayer-RokitanskyKüster-Hauser de tipo II, constituye una rara malformación que afecta aproximadamente a una de cada 50.000 mujeres [1,2]. Consiste en la combinación de aplasia de los conductos de Müller, aplasia o ectopia renal unilateral y displasia de los somitas cervicodorsales, relacionado con deformidades vertebrales del espectro Klippel-Feil, y asociado o no a malformaciones occipitoatloideas [2]. La disección de la arteria vertebral es una causa poco frecuente de ictus, que puede asociarse a anomalías del desarrollo craneocervical [3]. Se describe un caso de ictus causado por disección de la arteria vertebral en...

  11. 2D visualization and measurement of the fetal optic chiasm. Improving the counselling of antenatal diagnosis of agenesis of the septi pellucidi.

    Viñals, F; Ruiz, P; Correa, F; Pereira, P
    To develop an objective method to visualize and measure the optic chiasm (OC) through a 2D coronal vaginal plane and to report measurements in fetuses with agenesis of the septi pellucidi (SP). METHODS: This was a prospective cross-sectional study of 115 morphologically normal fetuses in low-risk pregnancies, between 21 and 30 weeks' gestation. OC was measured in a coronal plane at the level of the third ventricle and was seen as a horizontally aligned dumbbell-shaped structure of moderate echogenicity. In addition, OC measurements from eight fetuses with agenesis of the SP and complete follow-up were compared to the reference range. RESULTS: OC measurements were...

  12. High-risk features in potentially resectable colon cancer: a prospective MDCT-pathology agreement study

    Santiago, I; Rodrigues, E; Germano, A; Costa, A; Manso, R; Gomes, A; Leichsenring, C; Geraldes, V
    Neoadjuvant chemotherapy in potentially resectable high-risk Stage II and Stage III colon cancer has demonstrated promising results in the PRODIGE 22-ECKINOXE Phase II trial. Identification of adverse morphologic features, namely T3 with >5 mm extramural extension/T4 stages and/or N2, is fundamental and requires accurate noninvasive imaging. Our aim was to assess the value of optimized preoperative MDCT to stratify potentially resectable colon cancer patients for neoadjuvant therapy. METHODS: this is an observational prospective cross-sectional radiologic-pathologic agreement study. All patients with colon cancer referred to our Institution's Radiology department for preoperative MDCT staging between 01-10-2013 and 11-02-2015 underwent independent reading based on axial...

  14. An ontogenetic approach to gynecologic malignancies

    Santiago, I; Gomes, A; Heald, R
    Ontogenetic anatomy is the mapping of body compartments established during early embryologic development, particularly well demarcated in the adult pelvis. Traditional cancer surgery is based on wide tumour excision with a safe margin, whereas the ontogenetic theory of local tumour spread claims that local dissemination is facilitated in the ontogenetic compartment of origin, but suppressed at its borders in the early stages of cancer development. Optimal local control of cancer is achieved by whole compartment resection with intact margins following ontogenetic "planes". The principles embodied in this hypothesis are most convincingly supported by the results of the implementation of total...

  15. Pancreatic neuroendocrine tumors: correlation between histogram analysis of apparent diffusion coefficient maps and tumor grade

    Pereira, JA; Rosado, E; Bali, M; Metens, T; Chao, SL
    Purpose: To explore the role of histogram analysis of apparent diffusion coefficient (ADC) MRI maps based on entire tumor volume data in determining pancreatic neuroendocrine tumor (PNT) grade. Methods and Materials: Retrospective evaluation of 22 patients with PNTs included low-grade (G1; n = 15), intermediate-grade (G2; n = 4), and high-grade (G3; n = 3) tumors. Regions of interest containing the lesion were drawn on every section of the ADC map containing the tumor and summated to obtain histograms for entire tumor volume. Calculated histographic parameters included mean ADC (mADC), 5th percentile ADC, 10th percentile ADC, 25th percentile ADC, 50th per- centile ADC, 75th percentile ADC (ADC75), 90th percentile ADC (ADC90) and 95th percentile...

  16. “Um nó no estômago”: volvo gástrico

    Penha, D; Rodrigues, E; Paixão, P; Schmitt, W; João, P; Pinto, E; Costa, A
    O volvo gástrico é caracterizado por uma rotação anómala do estômago sobre os seus eixos. Embora seja uma causa rara de oclusão, pode apresentar-se clinicamente de forma aguda ou crónica, com períodos de obstrução intermitente. É impor- tante o reconhecimento desta patologia, no sentido de evitar graves complicações médicas e cirúrgicas. Assim, perante um volvo gástrico é imperativo um diagnóstico clínico e imagiológico correto e precoce. Com o presente artigo, pretendemos através de uma breve revisão bibliográfica definir a patologia em questão, bem como ilustrar através de exames fluoroscópicos com contraste do tubo digestivo, a classificação do volvo gástrico em orga- noaxial, mesenteroaxial...

  19. Duodeno-colic fistula as a rare presentation of lung cancer - surgical treatment of a stage IV oligometastatic lung disease

    Nunes, V; Santiago, I; Marinho, R; Pires, D; Theias, R; Gomes, A; Pignatelli, N
    INTRODUCTION: Rare adenosquamous carcinomas have no defined standard approach given their low incidence. They present with nonspecific imaging characteristics and are described as having worse prognosis than other lung malignancies, with greater likelihood of local invasion and early metastasis. PRESENTATION OF CASE: Male caucasian patient, 43 years, 26 pack-year smoking history, presented with watery diarrhea, early emesis and loss of 25% body weight (20kg) in four weeks. Colonoscopy identified a left colonic mass. Abdominal CT/ultrasound showed a large fistulous lesion between the 4th portion of the duodenum and left colon. CT showed a solid mass in the right upper lung lobe. Endoscopy and...
