Subgaleal Abscess in the Newborn - The Annals of Pediatric Surgery

pyrexia persisted. By the 6 th day of admission, thescalp swelling became fluctuant and starteddischarging pus spontaneously (Fig 1). Culture of thepus was sterile. An incision and drainage was doneand 60mls of thick, creamy and inoffensive pusdrained from the subgaleal space. The abscess cavitywas dressed and packed daily with honey-soakedgauze. The child subsequently did well, the abscesscavity gradually reduced and the wound healed. Hewas discharged after 22 days in hospital and hasremained well after 6 months.Fig 1. The abscess, discharging thick creamy pusDISCUSSIONSubgaleal abscess is rare in the newborn. Mostreported cases occurred following scalp trauma, orneedle electrode inserted for fetal monitoring. 2-4Although, infected scalp wounds are generallylimited and readily treated, they can progress if notpromptly and adequately managed. 5 Although directspread through scalp bruises is the mechanism ofinfection in most reported cases, this abscess has beenreported following minor trauma with a scalp wound.The patient in the present report may have developeda haematoma, which became infected byhaematogenous route from the uvulectomy.The bacteriology of subgaleal abscess in the fewreported cases revealed the predominance ofStreptococcus species among the bacterial isolates.Group A β haemolytic streptococcus 3 and group Cstreptococcus such as Streptococcus cremoris 6 andStreptococcus viridans, 2 are among the frequentlyreported agents. Other bacteria isolated includecoagulase negative staphylococci, Eilkenellacorrodens, Edwardsiella tarda 7 andPeptostreptococcus micros. 2 However in this report,the abscess was sterile probably due to antibioticsadministered before the swelling became fluctuant.Several extracranial and intracranial complicationscould arise from subgaleal abscess. These includecranial osteomyelitis and sinusitis due to closeproximity of the subgaleal space to these structures.Intracranial extension could occur through theemissary veins resulting in cavernous or superiorsaggital sinus thrombosis, meningitis and intracranialabscess. No complications occurred in our patient.The diagnosis of subgaleal abscess is mainly clinical.Needle aspiration should confirm the presence of pus.CT scan, when available is helpful to excludeintracranial complications.In early cases, complete aspiration by wide boreneedle and antibiotics may be effective. However, ifthe collection recurs, and in large abscesses, adequateincision and drainage is necessary. The abscess in thisbaby was large, and required incision and drainage.In newborns with suspected cephalhaematoma,needle aspiration should be done to exclude anabscess if fever persists. Prompt treatment of anyabscess is necessary to prevent complications.REFERENCES1. Endicott JN, Nelson RJ, Saraceno CA.
