title: Ilio-psoas abscess caused by methicillin-resistant Staphylococcus aureus (MRSA): a rare but potentially dangerous condition in neonates.
abstract: We report a case of methicillin-resistant Staphylococcus aureus ilio-psoas abscess (IPA) in a neonate. This case has clinical importance because this neonate had toxic shock syndrome-like exanthematous disease, known as NTED, before developing IPA. A high index of suspicion is required for IPA if a neonate presents with limb disuse and fever of unknown origin. Our case required surgical drainage, since ultrasound-guided percutaneous needle aspiration failed.
