Iliopsoas abscess is extremely rare in childhood. Early diagnosis and treatment is crucial to reduce mortality and hip damage. Here we present a case report of a 30-day-old newborn boy with bilateral iliopsoas abscess. His family presented him to the neonatal outpatient clinic with complaints of restlessness and swelling in bilateral inguinal regions. A diagnosis of bilateral Iliopsoas abscess was made using ultrasonography and rapid abdominal Magnetic Resonance Imaging (MRI). The treatment was achieved by percutaneous abscess drainage and systemic antibiotic treatment. He recovered completely after treatment.
