Spanish to English Medical Medical (general) PET/CT scans - cancer

I'm confused about this term. I'm working on a series of PET/CT scan reports of studies on patients with metastatic cancer; the reports describe the scan findings in the organs involved (colon, liver, lungs) as well as "adenopatias" ... some examples:

"Actividad metabólica tumoral en adenopatías periportales y en hilio hepático."
"Estabilidad morfometabólica en adenopatias hiliar pulmonar derecha."
"Hay adenopatías prevasculares, paratraqueales bilaterales, subcarinales ...."
"Imagen sólida hipermetabólica ... sugestiva de adenopatia tumoral."
"Disminución metabólica en las múltiples adenopatias descritas."

This is actually a proofreading job ... the translator used "adenopathies" each and every time for this term. And I'm wondering whether it might not mean simply "lymph nodes" in certain cases, and actually "adenopathies" [meaning disease of the lymph nodes] in others. Or maybe it would be translated as "diseased lymph nodes"?

I think that the standard term for lymph nodes in Spanish is "ganglios linfáticos" ... but I'm just getting confused by the way "adenopatías" is used in the above sentences, and the additional example below

Another sentence says "No apreciamos adenopatias hiliares, ni mediastínicas." Would I translate this as "We do not find hilar or mediastinal adenopathies" or "We do not find diseased hilar or mediastinal
lymph nodes"?

Thank you for your help with this.
