Introdução: O osso navicular é um dos ossos do tarso que mais raramente sofre uma fratura. Com o formato de um barco e posicionado entre a cabeça do tálus e dos três cuneiformes, desempenha um papel importante na sustentação da coluna medial do pé. Uma vez fraturado, pode ter seu diagnóstico feito através da radiografia, tomografia computadorizada, ressonância magnética ou ainda por cintilografia óssea. Objetivo: Relatar um caso incomum de fratura do osso navicular, diagnosticado apenas pela ressonância magnética. Relato do Caso: Mulher de 41 anos que após uma queda referiu dor em seu pé direito com piora ao caminhar. Apresentava dor à palpação na porção medial e dorsal do mediopé e edema. Radiografia do pé normal. A ressonância magnética apresentou traço de fratura na porção medial do osso navicular. Conclusão: Apesar de incomum, as fraturas do mediopé devem ser pesquisadas com métodos de imagem e, mesmo quando a radiografia seja normal, na continuação da sintomatologia do paciente, exames de maior acurácia devem ser realizados, tais como a TC e a RM.Palavras chave: Ossos do tarso, Fraturas ósseas, Imagem por ressonância magnéticaABSTRACT:Introduction: The navicular bone is one of the tarsal bones that most rarely suffers a fracture. Shaped like a boat and positioned between the head of the talus and the three cuneiforms, it plays an important role in supporting the medial column of the foot. Once fractured, the diagnosis can be made through radiography, computed tomography, magnetic resonance imaging, or even bone scintigraphy. Objective: To report an unusual case of fracture of the navicular bone, diagnosed only by magnetic resonance imaging. Case Report: A 41-year-old woman who, after a fall, reported pain in her right foot, which worsened when walking. He had pain on palpation in the medial and dorsal portion of the midfoot and edema. The radiograph of the foot is normal. Magnetic resonance imaging showed a fracture in the medial portion of the navicular bone. Conclusion: In spite of being uncommon, midfoot fractures should be investigated with imaging methods and, even when the radiograph is normal, in the continuation of the patient’s symptoms, more accurate tests should be performed, such as CT and MRI.

✓ The authors present an unusual case of intramedullary arachnoid cyst diagnosed in a patient after the lesion was resected. A wide decompressive surgery was performed and the lesion removed. Histopathological findings were consistent with the diagnosis of arachnoid cyst. Postoperatively the patient exhibited marked improvement in neurological status. To the best of the authors' knowledge, there is no case report of intramedullary arachnoid cyst reported in the literature. With the advent of newer neuroimaging modalities such as magnetic resonance imaging the number of cases of intramedullary arachnoid cysts encountered in the future may increase.

Introdução: A coalizão tarsal representa uma comunicação anormal entre ossos do tarso e pode ser óssea, cartilaginosa ou fibrosa, se desenvolvendo de forma secundária a insuficiência da diferenciação e segmentação do mesênquima primitivo nas primeiras fases do desenvolvimento, diminuindo a mobilidade e deformando os pés, quando congênita. Quando adquirida ocorre devido à artrite inflamatória, infecção, trauma, neoplasia, entre outras causas. Relato de Caso: Relatamos o caso de uma mulher de 37 anos com queixa há um mês, desmontando a importância da investigação da causa e a necessidade de atenção por parte do radiologista para a avaliação das coalizões tarsais visto que, uma coalizão, independentemente de quais ossos envolvidos, pode levar a uma sintomatologia limitante. Palavras chave: Ossos do tarso, Coalizão tarsal, Imagem por ressonância magnética, Deformidades do péAbstractIntroduction: Tarsal coalitions represent abnormal bridging between tarsal bones and can be osseous, cartilaginous, or fibrous, developing secondary to failure of differentiation and segmentation of the primitive mesenchyme in the first stages of development, decreasing mobility and deforming the feet, when is congenital. When acquired it occurs due to inflammatory arthritis, infection, trauma, neoplasia and other causes. Case report: We report the case of a 37-year- -old woman with a complaint a month ago, dismantling the importance of investigating the cause and the need for attention by the radiologist for the evaluation of tarsal coalitions since, a coalition, regardless of which bones involved, can lead to limiting symptoms.Keywords: Tarsal bones, Tarsal coalition, Magnetic resonance imaging, Foot def

Abstract Background Management of postoperative chylothorax usually consists of nutritional regimens, pharmacological therapies such as octreotide, and surgical therapies such as ligation of thoracic duct, but a clear consensus is yet to be reached. Further, the variation of the thoracic duct makes chylothorax difficult to treat. This report describes a rare case of chylothorax with an aberrant thoracic duct that was successfully treated using focal pleurodesis through interventional radiology (IVR). Case presentation The patient was a 52-year-old man with chylothorax after a thoracoscopic oesophagectomy for oesophageal cancer. With conventional therapy, such as thoracostomy tube, octreotide or fibrogammin, a decrease in the amount of chyle was not achieved. Therefore, we performed lymphangiography and pleurodesis through IVR. The patient appeared to have an aberrant thoracic duct, as revealed by magnetic resonance imaging (MRI); however, after focal pleurodesis, the leak of chyle was diminished, and the patient was discharged 66 days after admission. Conclusions Chylothorax remains a difficult complication. Focal pleurodesis through IVR can be one of the options to treat chylothorax.
