Baker’s cyst and procalcitonin

A burst cyst can cause calf pain, swelling and redness that may mimic thrombophlebitis or a potentially life-threatening deep vein thrombosis (DVT) which may need to be excluded by urgent blood tests and ultrasonography. Although an infrequent occurrence, a Baker’s cyst can compress vascular structures and cause leg edema and a true DVT.

Procalcitonin (PCT) is a peptide precursor of the hormone calcitonin, the latter being involved with calcium homeostasis.
