[Cervical myelopathy induced by calcium pyrophosphate tophus in primary chondrocalcinosis].

A 78 year old female patient with cervical myelopathy induced by a calcium pyrophosphate dihydrate tophus around the dens axis with clinical signs of a cervical tumor is presented. After operation of the tumor, the diagnosis of a generalized CPPD disease was established retrospectively, where by patient had complained of joint pain already for many years. This known complication of a primary chondrocalcinosis should be a reason for a careful investigation of the cervical spine in CPPD disease, because neurological disturbances might increase the joint destruction in the manner of "Charcot joints".
