español al inglés Medicina Medicina (general) medical report

Hello

I am translating a medical report and an autopsy report about multiple organ failure.

TAC tórax-abdomen-pelvis:

Derrame pleural bilateral de forma ligera. Se observan adenomegalias mediastínicas centimétricas. El higado tiene tamano conservado; no se aprecian formaciones nodulares ni dilatación de la vía bilar intrahepática.

Does this mean "every few centimetres" or "a few centimetres in size"??

Thank you! [and it's not even a medical word!!]
