Calcium pyrophosphate deposition disease in the ankle joint: a case report.

OBJECTIVE: To detail the presentation of calcium pyrophosphate deposition disease (CPPD) in the ankle joint. The aim of this case report is to inform health-care practitioners about the presentation of this condition in an uncommon location and discuss the diagnosis, potential treatment, and management strategies for a patient with CPPD.

CLINICAL FEATURES: A 36-year-old male patient presented to a chiropractic clinic with an acute, painful, and swollen ankle, which was later diagnosed by plain film radiograph as CPPD. A rheumatology follow-up was recommended and at-home treatment was prescribed to treat acute symptoms and monitor progress.

OUTCOME: No chiropractic treatment was provided and the patient has been referred to a rheumatologist for further assessment. The diagnosis of CPPD was confirmed and he was advised to take an anti-inflammatory if symptoms recurred and booked for further follow-up in six months.

SUMMARY: Although the presentation is less common, CPPD can present in the ankle joint and mimic other inflammatory disorders. Conservative treatment can be applied to treat acute symptoms and referral to a rheumatologist is suggested to monitor progress of this condition.
