Abstract

Background: Intracranial abscesses are rare and have grave consequences if not treated early. There are several surgical treatment modalities, including ultrasound-guided aspiration, which has been proven to be a quick, safe and cost-effective means of evacuation. This may be carried out through a burrhole or through a pre-existing cranial defect such as the anterior fontanelle.

Aims and Objectives: To demonstrate the benefit of ultrasound-guided aspiration of intracranial abscesses in infants and older children.

Materials and Methods: Five children (four infants aged 2 to10months, all of whom were females, and a 14-year old male) with various intracranial abscesses had surgical evacuation after detailed clinical and radiological evaluation. One had multiple burrholes for evacuation of multiple abscesses, but did not survive; two had initial burrhole evacuation followed by ultrasound-guided evacuation for recurrent or residual abscess. The remaining two had ultrasound-guided evacuation for both the initial evacuation and the follow-up procedure for evacuation of recurrent or residual abscesses.

Results: One of the infants had multiple burrholes for drainage of 600mls of pus as the first and only procedure. She died after 48hours. The other four had two-staged procedures involving either burrhole or ultrasound-guided evacuation as initial procedure, followed by ultrasound-guided evacuation alone as second procedure for recurrent or residual abscesses. The latter improved and were discharged without further neurological deficits.

Conclusion: Ultrasound-guided aspiration of intracranial abscesses under local anesthesia is a quick, safe, and cost-effective means of evacuating multiple abscesses in infants and older children. This is useful in settings with limited resources especially for patients who may be too ill for general anaesthesia.
