Gorham-Stout syndrome is a disease that presents idiopathic osteolysis of a bone or closely contiguous area. The etiology is unknown. It is a rare condition that is difficult to diagnose, and its treatment is controversial. It affects individuals irrespective of age or sex. In this study, we conducted a bibliographic review of the disease, specifically focusing on the differential diagnosis, and we demonstrated the follow-up on a patient with this syndrome from the time of its diagnosis, through treatment, to its current state of evolution.
The aim of this study was to evaluate the accuracy of simple radiography, ultrasound and magnetic resonance imaging (MRI) in diagnosing rotator cuff injuries, comparing their findings with open or arthroscopic surgery findings. Methods: Protocols of the Shoulder and Elbow Surgery Service for patients undergoing surgical treatment for rotator cuff injuries diagnosed by means of radiography, ultrasound and/or MRI between 2002 and 2007 were evaluated. Based on the data gathered, we analyzed the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of these complementary examinations, compared with the findings during the surgical procedures. Results: This study included 147 patients with a mean age of 46.09 years. All the patients had undergone a radiography examination, 101 had undergone ultrasound examination and 72 had undergone MRI. We found sensitivity of 13.8%, specificity of 2.6% and accuracy of 30% with radiography; sensitivity of 57.6%, specificity of 29.6% and accuracy of 51.4% with ultrasound; and sensitivity of 86.6%, specificity of 22.2% and accuracy of 63.3% with MRI. Conclusion: Radiography was found to be a specific examination when the mirror sign was present. MRI and ultrasound were shown to be reliable methods with high accuracy for diagnosing rotator cuff injuries.
RESuMOA síndrome de Gorham-Stout é uma doença que apresenta osteó-lise idiopática de um osso ou área contígua próxima. A etiologia é desconhecida, sendo uma condição rara, de difícil diagnóstico e tratamento controverso. Acomete pessoas sem distinção quanto à idade e ao sexo. Neste trabalho realizamos uma revisão bibliográfica da doença, dando enfoque específico no diagnóstico diferencial, e demonstramos o acompanhamento de um paciente com esta síndrome, desde o seu diagnóstico, tratamento e estado atual de evolução.

RESUMOObjetivo: A proposta do trabalho é avaliar a acurácia da radiografia simples, ultrassonografia e ressonância nuclear magnética no diagnóstico das lesões do manguito rotador, comparando-os com os achados em cirurgias abertas ou artroscópicas.
INTRODUçãOAs lesões do manguito rotador constituem uma causa frequente de dor no ombro em pessoas de todas as idades. Essa condição representa um espectro de doenças, que varia desde uma tendinite aguda reversível até uma lesão maciça envolvendo todos os seus componentes (1) .O diagnóstico dessa doença é obtido pela história clínica e exame físico, incluindo suas manobras semio-
