Se considera una masa intrahepática aquella lesión expansiva focal que está constituída por un tejido distinto al del parénquima hepático normal. Puede ser única o múltiple, sólida o quística, benigna o maligna. Generalmente se identifica por la ecografía abdominal.
Etiología
El diagnóstico diferencial comienza con el interrogatorio:
· Contexto clínico :
- hallazgo incidental en un paciente sano.(Tumor benigno)
- síntomas : dolor y/o masa palpable en hipocondrio derecho. (Tumores
malignos o benignos complicados)
- paciente con sindrome de impregnación. (Tumor maligno)
- seguimiento de un paciente con hepatopatía crónica. (Hepatocarcinoma)
· Uso de anticonceptivos orales (adenoma), factores de riesgo para hepatopatía crónica (hepatocarcinoma), antecedentes de neoplasia extrahepática (metástasis), antecedentes de viajes (absceso amebiano), flushing o síntomas cardiovasculares (metástasis de carcinoide).
