Monoarticular pseudogout of the hip presenting as septic arthritis: a case report.

Calcium pyrophosphate dihydrate (CPPD) disease is the second most common crystal-induced form of arthropathy, frequently seen in the knee, shoulder, wrist, elbow, and ankle. The acute form of the disorder is referred as pseudogout, which can cause a severe joint inflammation. We present a case of monoarticular pseudogout of the hip joint whose symptoms mimicked septic arthritis. The definitive diagnosis was only confirmed after the microscopic analysis of joint aspirate.
