Case Discussion
Rarely encysted pleural effusions are identified in the fissures. This is the first time I have had a case of an encysted perifissural hydropneumothorax.
Air and fluid have equal rights to track into the fissure. It's a pretty unusual (and cool) appearance, which if one approaches logically and with first principles makes sense.
A good case to try on friends, especially those prior to a VIVA exam.
