title: Recurrent tendinitis and achilles tendon nodule with positively birefringent crystals in a patient with hyperlipoproteinemia.
abstract: We describe a patient with hypercholesterolemia and premature coronary artery disease. Positively birefringent suspected lipid crystals were aspirated from a retrocalcaneal bursa and an Achilles tendon nodule. These crystals may have been a factor in the tendinitis and could be confused with calcium pyrophosphate dihydrate crystals.
