Putty kidney

A putty kidney refers to a pattern of renal calcification associated with renal tuberculosis conventionally described on plain radiography. Calcification characteristically is very homogeneous and ground glass like, representing calcified caseous tissue 3-4. Premkumar et al labelled calcification 'putty like' if any faint area of uniform calcification was more than 1 cm in diameter 4. Putty calcification needs to be differentiated from 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.
