Gout is the most common form of microcrystal arthropathy that results
in deposition of uric acid crystals in and around the joints and soft
tissues. The most common cause is decreased uric acid clearance by
the kidneys. The radiological manifestations of gout are generally well
known and have remained unchanged. We describe a case of chronic
tophaceous gout with diffuse extensive involvement of the synovium
around the knees bilaterally.
