Morphology

pseudocyst = cyst (semi-transparent) = pseudo + cyst

The term is built transparently from pseudo- + cyst, but the exact medical sense is specialized and not fully predictable for a learner.

Etymology

The word pseudocyst comes from the parts pseudo- meaning 'false' and cyst meaning 'sac' or 'bladder'. So, a pseudocyst is a 'false sac', a fluid pocket that looks like a cyst but does not have a true lining.
