Morphological characteristics of liver abscesses according its etiology / Características morfológicas de los abscesos hepáticos según su etiología

Although infrequent in the diagnostics areas, liver abscesses are of significant relevance, which is related to the high morbidity and mortality figures they can cause if they are not detected and treated in time. Although multiple operational classifications are described, the one most recognized for its usefulness is that related to its causative agent (pyogenic or bacterial infection, hydatid origin or secondary to infected hydatidosis, and amoebic or by invasive amebiasis). The objective of this article was to generate a study report regarding the morphological characteristics of liver abscesses, characterizing them according to their etiology, as well as describing their study and the latest recommended treatments.

Los abscesos hepáticos son entidades nosológicas de baja frecuencia, pero de significativa relevancia, la que se relacionada con las elevadas cifras de morbilidad y mortalidad que pueden causar si no son detectados y tratados a tiempo. Si bien se describen múltiples clasificaciones operacionales, aquella más reconocida por su utilidad es la relacionada a su agente causal (piógenos o bacterianos, hidatídicos o secundarios a hidatidosis infectada, y amebianos o por amebiasis invasora). El objetivo de este artículo fue generar un documento de estudio respecto de las características morfológicas de los abscesos hepáticos, caracterizándolos de acuerdo con su etiología, así como describir su estudio y tratamiento recomendado de acuerdo con el estado del arte.

Liver abscesses with portal and mesenteric vein thrombosis: a rare complication of appendicular peritonitis

Pyogenic liver abscesses are caused by appendicitis in less than 10%. Also the ascending septic inflammation of portal vein [pylephlebitis] could be a serious complication of intra-abdominal infection. Although pylephlebitis is not frequent today, its mortality and morbidity rates remain high. We describe a case of pylephlebitis, portal-mesenteric thrombosis, and multiple liver abscesses, caused by appendicular peritonitis. The patient was admitted three weeks after appendectomy with the chief complaints of high fever and chills. He was diagnosed of pylephlebitis, portal-mesenteric thrombosis, and multiple liver abscesses by CT-scan. He was treated with long-term antibiotics and anticoagulation
