Its propensity to affect the terminal ileum and to spread to regional lymph nodes explains the potential misdiagnosis with appendicitis.  Methods:  We reviewed the Y. enterocolitica infection cases in a pediatric population for the last 12 years.  Results:  There were 11 cases of Y. enterocolitica infection in the selected period. Four patients had a suspected surgical diagnosis: 1 intussusception, 3 acute appendicitis. Patients who presented with appendicitis-like features were older, whereas younger children most commonly presented with diarrhea and fever. Ultrasound and abdominal computed tomography (CT) were performed in appendicitis-like patients and ruled out appendicitis in 2 of the 3 cases. The only patient submitted to surgery had abnormal CT findings and an important risk factor for this infection that was not recognized at presentation.  Conclusion:  This condition should be considered in patients with known risk factors (such as iron overload) and with the right epidemiological setting when presenting with abdominal symptoms. The suspicion of this diagnosis in these particular cases might obviate unnecessary surgical interventions.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo:  Introdução:  A infecção por Yersinia enterocolitica é uma zoonose que se pode apresentar como uma gastroenterite auto-limitada ou assumir formas mais graves. A sua propensão em afectar o íleo terminal e, consequentemente, os gânglios linfáticos regionais explica o potencial confundimento diagnóstico com a apendicite aguda.  Métodos:  Foram revistos todos os casos reportados de infecção por Y. enterocolitica em população pediátrica, nos últimos 12 anos.  Resultados:  Foram identificados 11 casos de infecção por Y. enterocolitica no período selecionado. Em 4 destes pacientes foi suspeitado inicialmente um diagnóstico cirúrgico: 1 invaginação intestinal e 3 apendicites agudas. Os doentes que apresentaram caraterísticas típicas de apendicite aguda eram mais velhos, enquanto os pacientes de menor idade mais comumente se apresentaram com diarreia e febre. Nos doentes com suspeita de apendicite, a ecografia e a tomografia computorizada abdominal foram realizadas em todos os doentes e excluíram o diagnóstico em 2/3 casos. O único paciente submetido a cirurgia tinha relato de alterações radiológicas típicas de apendicite aguda e apresentava um factor de risco importante para a infecção por Y. enterocolitica que não foi inicialmente reconhecido.  Conclusão:  O diagnóstico de Yersinose deve ser suspeitado em doentes com sintomas gastrointestinais que apresentem fatores de risco (sobrecarga de ferro) e o contexto epidemiológico adequado. A suspeição precoce deste diagnóstico neste contexto pode evitar intervenções cirúrgicas desnecessárias.]]></p></abstract>
