Late onset subgaleal hemorrhage infection with Streptococcus pneumoniae?

Abstract

We report a case of an infected subgaleal hematoma caused by an unusual micro-organism in a previously healthy 11-month-old girl. Our patient presented at the emergency department with an increasing scalp swelling for 2 weeks, and culture of the evacuated fluid yielded Streptococcus pneumoniae. Although she was born after vacuum delivery and a scalp swelling was noticed from the third day of life, this swelling disappeared completely at the age of 3 months. Parents were thoroughly questioned but we could not find out a new traumatic head event. We postulate that in our patient, a subgaleal hemorrhage developed after vacuum delivery and possibly infected 11 months later, presumably from hematogenous seeding of an acute otitis media. The patient recovered well after surgical drainage and antimicrobial therapy.
