MEDULLARY BONE INFARCTS.
This is a characteristic appearance of medullary bone infarcts. Most commonly they are in the diaphysis and metaphysis but in this case they also extend to the epiphysis.
The important think to note here is that its involving multiple areas. When there are multiple locations, think of an underlying cause such as SLE (vasculitis) or steroids.
This patient had steroids.
Thank you to Dr Joe Thomas for the case.
Bilateral medullary femoral and tibial serpiginous STIR hyper-intensity with extension into the femoral and tibial epiphysis.
