ABSTRACT
Post-traumatic cyst-like lesions are an infrequent complication of fractures in children. To our knowledge, no more than 30 cases have been reported in the English-language literature. They most commonly affect the distal radius following a greenstick or torus fracture. These cortical defects are often asymptomatic, non-expansile, and typically resolve spontaneously in 1-3 years. They appear proximal to the compression site and are usually identified 2-4 months after a minor fracture. These lesions have a distinct appearance on magnetic resonance imaging (MRI), with intralesional fatty marrow, which may help to differentiate it from other bone lesions. We review the literature and present 3 more cases studied with plain radiographs, computed tomography (CT), and MRI. Post-traumatic cyst-like lesions require no treatment, and therefore recognition of its typical features is crucial to prevent unnecessary invasive procedures.

The authors present a case of a neuroendocrine carcinoma in an asymptomatic 75-year-old woman, detected in routine breast screening. The lesion was visible at mammography as a well circumscribed, medium density nodule, with no associated microcalcifications, and at ultrasonography as a hypoechoic nodule, with irregular shape and ill-defined margins. Magnetic resonance imaging revealed findings consistent with malignancy.
Os autores apresentam um caso de carcinoma neuroendócrino numa mulher de 75 anos assintomática detectado em estudo imaginológico mamário de rotina. A lesão apresentava-se na mamografia como nódulo bem circunscrito de média densidade, sem microcalcificações associadas e ecograficamente como nódulo hipoecogênico de morfologia irregular e limites mal definidos. Na ressonância magnética mamária as características da lesão eram concordantes com malignidade.
