Morphology

extramedullary = medullary (semi-transparent) = extra + medulla + ary

Adding the productive prefix 'extra-' to 'medullary' yields the literal meaning 'outside the medulla', which is a straightforward semantic composition.

Etymology

Extramedullary breaks into extra- meaning 'outside' and medullary from medulla meaning 'marrow' or 'the soft centre of a bone'. So an extramedullary mass or lesion is one that lies 'outside the bone marrow' or outside the spinal cord, which is why doctors use the word for growths found outside those areas.
