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.

Inguinal abscess in twin infants

“…Inguinal abscess is uncommon in infants and children. [1][2][3] It can be primary which is idiopathic or has no detectable source and secondary in which the source of infection is direct spread from adjacent structures. [1][2][3] Majority of inguinal abscess in the infantile period is primary.…”

“…[1][2][3] It can be primary which is idiopathic or has no detectable source and secondary in which the source of infection is direct spread from adjacent structures. [1][2][3] Majority of inguinal abscess in the infantile period is primary. 1,2 The proposed hypothesis in case of primary abscess is that the normal flora of the skin spreads haematogenously due to immature immune system in infants.…”

“…[1][2][3] The most common organism seen in primary inguinal abscess is Staphylococcus aureus. 1,2 In case of secondary inguinal abscess common organisms implicated are Staphylococcus aureus, Streptococcus pneumoniae and Escherichia coli. 1,2 We present 2 cases of twin infants who presented with similar complaints consecutively with the diagnosis of inguinal abscess in whom early diagnosis let to quick and complete recovery.…”
