Los hallazgos cl\u00ednicos e imagenol\u00f3gicos generaron una fuerte sospecha de malignidad. El cultivo microbiol\u00f3gico del material de drenaje aisl\u00f3 Actinomyces shaaliae georgiae, reforzando la sospecha de proceso neopl\u00e1sico debido a la presentaci\u00f3n pseudotumoral.\nTratamiento y Resultados:El manejo inicial incluy\u00f3 terapia antimicrobiana y drenaje percut\u00e1neo.

Las lesiones actinomic\u00f3ticas forman focos purulentos rodeados de fibrosis extensa, creando masas pseudotumorales que cl\u00ednica y radiol\u00f3gicamente simulan procesos neopl\u00e1sicos.
