However, CPPD in the cervical spine is a rare entity. This report describes a case of CPPD of the cervical spine which presents with symptoms of neck pain and brachalgia. A 62-year-old woman presented with left-sided upper limb and neck pain. MRI scanning revealed a low signal abnormality within the C6 and C7 vertebrae, and the possibility of lymphoma was raised. The patient was recalled for gadolinium-enhanced scans which showed perivertebral and marrow enhancement. Fine-needle aspirate histology initially suggested a spindle cell tumour or lymphoma. However, CT-guided biopsy showed positively birefringent crystals, confirming CPPD. CPPD of the spine is a rare differential of nerve impingement in the cervical spine when MRI scanning perivertebral signal enhancement. Furthermore, CPPD of the spine can mimic malignancy. %U https://casereports.bmj.com/content/bmjcr/12/12/e231508.full.pdf
