We report a unique case of neonatal mycotic internal iliac artery aneurysm managed non-operatively. The child had multifocal osteomyelitis and no history of umbilical artery catheterisation. The aneurysm was regularly scanned and monitored until its obliteration by thrombus 17 days after initial detection. Contingency plans for either interventional radiological coiling or open surgical repair were in place had the aneurysm grown or the child deteriorated.
