Abstract

It is rare entity especially in childhood. Case: We are reporting case of xanthogranulomatous pyelonephritis in 2 month male baby presented as left renal mass without signs of infections. On imaging it shows multicystic, heterogeneous, non-enhancing left renal mass. Conclusion: XGPN, itself is a rare entity presenting in infant/childhood of which presentation solely as renal lump without any signs and symptoms of urosepsis, UTI. Hence even in neonate/childhood one should consider it as one of D/D presenting as renal mass.
