Acute lobar nephronia (ALN) is a focal nonliquefactive bacterial infection affecting one or more renal lobules. Although it is a rare form of urinary infection, it has been diagnosed with increasing rates by the utility of ultrasonography (USG). The inflammatory markers are high in ALN, and it requires longer duration of antibiotic treatment. Effective treatment can prevent its progression to renal abscess. ALN may be seen in healthy children and those with urinary tract abnormalities as well. Here, we presented an infant with ureterolithiasis that developed ALN with prolonged fever. He was treated with intravenous antibiotics, and fever with USG findings were resolved. As ALN produces a moss lesion that may mimic other entities such as abscess or tumors, diagnosis is important for sufficient antibiotic treatment and avoidance of unnecessary invasive operations.
