Amebiasis is a relatively common infection in developing countries. Entamoeba histolytica is the parasitic agent responsible for invasive forms of this disease. Abdominal pain and hepatomegaly are classical findings when liver is affected and in some cases large volume abscesses may develop. Despite the mainstay for treatment remains antibiotics, interventional radiology techniques may be useful in more complicated cases. This report presents a case of invasive amebiasis affecting both the colon and liver of a 75 year old male. Diagnosis, treatment options and follow-up are discussed. The importance of abscess CT guided punction in specific lesions is emphasized. A amebíase constitui uma forma comum de infecção gastrointestinal nos países subdesenvolvidos, sendo a Entamoeba histolytica o agente parasitário responsável pelas formas invasivas da doença. A dor abdominal e a hepatomegalia são características clínicas típicas das situações em que se verifica envolvimento hepático, estando descritos na literatura casos de abcessos hepáticos volumosos. Ainda que a antibioterapia seja a base do tratamento, alguns casos mais complexos porém, exigem o recurso a outro tipo de técnicas diferenciadas, nomeadamente as de radiologia interventiva. Os autores reportam um caso de amebíase invasiva com atingimento intestinal e hepático num homem de 75 anos de idade. São discutidos o diagnóstico diferencial, as opções terapêuticas disponíveis e a evolução da doença.

This report shows that intravenous catheterisation has been required for 59.4% of the patients in this sample. The main reason identified for catheterisation was the difficulty in accessing peripheral veins. The wound dressing was applied for 100% of the patients and the procedure itself was carried out each 48 hours in 89.8% of them. The intravenous catheter stood for 10 days in 52% of the cases and it was removed in 34.8% for intravenous drugs interruption and the other reasons were related as to technical problems. The most present microorganism was Staphylococcus aureus in 20.3% of the catheter cultures.

Através do presente estudo pode-se concluir que a cateterização intravenosa foi efetuada em 59,4% da amostra por acesso venoso dificultado; em 100% da amostra foi efetuado curativo fechado, sendo que a troca do curativo foi feita a cada 48 horas em 89,8% da amostra; o tempo de permanência do cateter intravenoso foi de até 10 dias em 52% dos casos, sendo que o cateter foi retirado em 34,8% por suspensão da medicação e problemas técnicos, respectivamente. O microrganismo de maior incidência foi Stophylococcus aureus em 20,3% da amostra analisada.
