ABSTRACT
Resumo Objetivo: Identificar o perfil de utilização dos recursos didáticos pelos médicos radiologistas e residentes em radiologia e diagnóstico por imagem brasileiros. Materiais e Métodos: Estudo observacional, transversal e descritivo, realizado por meio de questionário eletrônico contendo perguntas referentes ao perfil do médico, formação, local de atuação, perfil de acesso a recursos educacionais e tipos de recursos mais utilizados. Resultados: Responderam ao questionário 265 médicos com idade média de 38,2 anos, sendo a maioria radiologistas formados (170; 64,2%), do sexo masculino (166; 62,6%), trabalhando em instituições privadas (174; 65,7%), sem vínculo acadêmico (167; 63,0%), atuando principalmente nas áreas de ultrassonografia (212; 80,0%) e tomografia computadorizada (206; 77,7%). A carga horária média de estudo semanal foi de 9,6 horas (mediana: 6 horas), sendo maior no grupo dos médicos que estão em formação e nos que atuam em instituições públicas e acadêmicas. Quanto ao recurso para o acesso do material de estudo, observou-se uma tendência pela maior utilização do computador (65,3%). A maioria dos respondentes optou por acessar materiais didáticos sem custo (61,9%), sendo os sites da web, livros e revistas eletrônicas os mais pesquisados. Conclusão: Os radiologistas brasileiros utilizam recursos eletrônicos e digitais como principais materiais didáticos, sendo os sites da web, livros e revistas eletrônicas as fontes mais utilizadas.
Abstract Objective: To profile the use of educational materials by radiologists and radiology residents in Brazil. Materials and Methods: This was a cross-sectional, descriptive, observational study in which an electronic questionnaire was sent via email to physicians working in the field of radiology. The questionnaire contained questions regarding the profile, education, and place of work of the physicians, as well as their access to educational resources and the types of educational materials they used most. Results: The questionnaire was completed by 265 physicians. The mean age of the respondents was 38.2 years. Of the 265 respondents, 212 (80.0%) worked with ultrasound, 206 (77.7%) worked with computed tomography, 170 (64.2%) were board-certified, 166 (62.6%) were male, 174 (65.7%) worked at private facilities, and 167 (63.0%) had no academic affiliation. The mean weekly total study time was 9.6 h (median, 6 h), being higher among physicians in training, among those who worked at public facilities, and among those who worked at teaching hospitals. Regarding the device employed in order to access educational materials, there was a trend toward greater use of computers, which were employed by 65.3%. The majority of the respondents (61.9%) chose to access educational materials that were free of charge, the most common sources being websites, eBooks, and online journals. Conclusion: Electronic and digital resources are the main means of access to educational materials used by radiologists in Brazil, the most commonly used resources being web sites, eBooks, and online journals.
ABSTRACT
Os autores descrevem um caso de massa abdominal epigástrica palpável associada a sintomas dispépticos em uma paciente jovem sem antecedentes patológicos. Estudos por imagem evidenciaram corpo estranho gástrico de "aspecto enovelado". A paciente foi submetida a gastrotomia via laparotomia, com retirada de um tricobezoar de 1.950 gramas.
The authors describe the case of a palpable epigastric mass associated with dyspeptic symptoms in a young female patient with no previous pathologic history. Imaging studies demonstrated the presence of a gastric foreign body with an "entangled appearance". The patient underwent laparotomy and gastrotomy for removal of a trichobezoar weighing 1,950 grams.

O tumor desmoplástico de pequenas células é uma neoplasia rara e extremamente agressiva que acomete predominantemente jovens do sexo masculino. Dor e distensão abdominal são freqüentes, ascite pode ser observada. Sua histogênese é incerta e a cavidade peritoneal é o local maiscomum de sua ocorrência. Este tumor é caracterizado por apresentar morfologia distinta e diferenciação multifenotípica. Apresentamos, neste relato, o caso de um adolescente admitido no serviçode Medicina Interna e Radiologia do Hospital e Maternidade Marieta Konder Bornhausen, Itajaí, SC, em 2005.
Desmoplastic small round cell tumor is a rare and highly aggressive neoplasm that predominantly occurs in young adult males. Pain and abdominal distention are frequent, ascites could be observed. His histogenesis is uncertain and the most common location is the peritoneal cavity. This tumor is characterized bypresenting a distinct morphology and polyphenotypic differentiation. We present in this report the case of an adolescent admitted in the service of Internal Medicine and Radiology of the Hospital and Maternity Marieta Konder Bornhausen, Itajaí, SC, Brazil,in year 2005.

CONTEXT AND OBJECTIVE: Computed tomography (CT) guided biopsy is widely accepted as effective and safe for diagnosis in many settings. Accuracy depends on target organ and needle type. Cutting needles present advantages over fine needles. This study presents experience from CT guided biopsies performed at an oncology center. DESIGN AND SETTING: Retrospective study at Hospital do Câncer A. C. Camargo, São Paulo. METHODS: 1,300 consecutive CT guided biopsies performed between July 1994 and February 2000 were analyzed. Nodules or masses were suspected as primary malignancy in 845 cases (65 percent) or metastatic lesion in 455 (35 percent). 628 lesions were thoracic, 281 abdominal, 208 retroperitoneal, 134 musculoskeletal and 49 head/neck. All biopsies were performed by one radiologist or under his supervision: 765 (59 percent) with 22-gauge fine-needle/aspiration technique and 535 (41 percent) with automated 16 or 18-gauge cutting-needle biopsy. RESULTS: Adequate samples were obtained in 70-92 percent of fine-needle and 93-100 percent of cutting-needle biopsies. The specific diagnosis rates were 54-67 percent for fine-needle and 82-100 percent for cutting-needle biopsies, according to biopsy site. For any site, sample adequacy and specific diagnosis rate were always better for cutting-needle biopsy. Among 530 lung biopsies, there were 84 pneumothorax (16 percent) and two hemothorax (0.3 percent) cases, with thoracic drainage in 24 (4.9 percent). Among abdominal and retroperitoneal biopsies, there were two cases of major bleeding and one of peritonitis. CONCLUSION: Both types of needle showed satisfactory results, but cutting-needle biopsy should be used when specific diagnosis is desired without greater incidence of complications.

As lesöes radiotransparentes da mandíbula e maxila podem apresentar aspectos radiológicos semelhantes, tais como localizaçäo, proximidade ou inclusäo dentária, caráter insuflante e densidade. Devido a tais semelhanças, estes sinais frequentemente näo säo suficientes para o diagnóstico. Entre essas lesöes, apresentamos cistos folículares, ameloblastomas, queratocistos, neurofibroma, carcinoma mucoepidermóide, lesäo de células gigantes e hemangioma, utilizando-se ortopantomografias, tomografias computadorizadas e, num caso específico, SPECT com hemácias marcadas na mandíbula. O objetivo deste trabalho é demonstrar as características radiológicas de algumas das lesöes radiotransparentes da maxila e mandíbula, de forma ilustrativa, cujo diagnóstico diferencial, às vezes, se torna muito difícil, mas que pode ser sugerido por intermédio de sinais que säo mais compatíveis com determinada lesäo
