Abstract
We have read an interesting case report concerning an X-ray finding in a patient taking lanthanum carbonate. Davidet al. explain the opacification on radiographsby intestinal calcium phosphate accumulation.
However,such strong opacification with a CT density of 3000 HU(Hounsfield value) has not been found in patients takingother types of phosphate binders including those containingcalcium (CT density of bone 600 HU). In our opinion, theremight be another explanation of this finding.
Below, we de-scribe a case of radio-opaque appearance of lanthanum ina patient taking this phosphate binder.
