title: Neonatal iliopsoas abscess.
abstract: Iliopsoas abscess (IPA) is rare in children, particularly in neonates. A male neonate was born at 38 weeks of gestation with a weight of 2915 g. On day 22 after birth, his family noticed that his right thigh was swollen. Abdominal computed tomography showed a mass extending to the right iliopsoas from the right thigh with thick septa. Puncture to the right groin yielded purulent fluid, and so a diagnosis of abscess was made. The puncture was followed by surgical drainage through a small inguinal incision, and the abscess cavity was irrigated thoroughly using normal saline. Culture of abscess fluid was positive for Streptococcus pneumoniae, so intravenous ABPC infusion was continued. The postoperative magnetic resonance imaging indicate that the IPA was derived from arthritis of the hip, and the patients received Riemenbügel for the incomplete hip dislocation. He is doing well at 2 years of age.
