Calcium pyrophosphate deposition disease, also known as pseudogout,
is a very common entity. Radiographically, the presence of
chrondocalcinosis is typical of this entity. Common locations
for chrondocalcinosis include the knee, symphysis pubis, and
triangular fibrocartilage at the wrist. Chrondrocalcinosis
in the setting of CPPD is commonly associated with calcification
of fibrocartilage. The AP radiograph of both knees shows chrondrocalcinosis
of the menisci. The lateral view of the left knee (Erin, this
is flipped vertically) shows calcification within the menisci.
The lateral view of the right knee (Erin, flipped horizontally)
also shows calcification of the menisci. Incidentally, also
noted in this patient is Paget's disease of the right tibia,
consisting of enlargement of the proximal tibia, thickening
of the cortex as well as a lucent advancing front (arrow).
