Moth eaten calyces

Moth eaten calyx refers to the ragged, feathery calyceal outline due to irregular erosions of the calyx. It is one of the earliest excretory urographic appearance of genitourinary tuberculosis


This appearance is due to necrotizing papillitis, which may further progress to form medullary cavities which may eventually communicate with the collecting system.
