Correct Answer

Yes I think it is pseudogout. Pseudogout is caused by the collection of salt called calcium pyrophosphate dihydrate (CPPD). The buildup of this salt forms crystals in the joints. This leads to attacks of swelling and pain in the knees (MOST COMMON), wrists, ankles, and other joints.

The correct answer is C) Pseudogout.

The X ray shows a knee with chondrocalcinosis which represents the calcification of the articulate cartilage. This is higly specific for pseudogout especially if it is bilateral.

Pseudogout is caused by deposition of calcium pyrophosphate crystals in the joint space. It affects large joints (most common the knee) and it is characterized by rhomboid crystals, weakly positively birefringent that are yellow when perpendicular and blue when parallel to the light.
