putty kidney

A putty kidney refers to a pattern of renal calcification associated with renal tuberculosis conventionally described on plain radiography. The calcification is characteristically very homogeneous and ground glass-like, representing calcified caseous tissue . Premkumar et al. labeled calcification 'putty-like' if any faint area of uniform calcification was more than 1 cm in diameter . Putty calcification needs to be differentiated from a lobar pattern of calcification, wherein dense calcific rims outline the periphery of distorted renal lobes. Lobar calcification represents an end-stage appearance, associated with autonephrectomy.
