RESUMO
Background: Treatment of brain abscess is still a subject of controversy. Simple therapeutic approaches like twist drill/burr hole aspiration with or without insertion of a drain are also quite effective. There are reports of encouraging results following endoscopic treatment. We are reporting our results of endoscopic approach on 24 patients. Materials and Methods: This is a prospective study on 24 patients of brain abscesses treated between January 2004 and January 2007. All the cases except those with small abscesses (less than 1.0 cm in diameter) and multiloculated abscesses were included. Gabb 6-degree rigid endoscope was used. Repeat CT scan was done in all cases within 7 and 30 days after surgery. Ten patients (42%) had small residual abscess on 7 th post-operative day's CT scan, while 30 th post-operative day's CT scan did not show any significant lesion in all the cases. Results: There were 23 patients of chronic otitis media and one of congenital cyanotic heart disease. Glasgow coma score (GCS) was 3 in one patient, 13 in two cases, 14-15 in 21 cases. There were 14 cerebellar, 8 temporal and 1 frontal and thalamic abscess each. All the patients recovered completely except one who died (GCS 3). There was no procedure-related complication. Hospital stay ranged from 7 to 12 days with an average of 8.2 days. Follow-up ranged between 6 and 42 months. Conclusion: Endoscopic aspiration of brain abscess appears to be a safe and effective alternative method of treatment. There is direct visualization of abscess cavity, completeness of aspiration can be assessed, and perioperative bleeding can be controlled.
RESUMO
Pediatric intramedullary schwannoma without neurofibromatosis is extremely rare with only five cases reported so far. We present this rare finding in an 8-year-old boy who presented with a sudden onset of weakness in all limbs. An intraoperative diagnosis of schwannoma enabled us to carry out a total excision of the tumor, which resulted in near complete recovery at 18 months follow-up. Although rare, this diagnosis should be considered when a child presents with a solitary intramedullary tumor, since its total resection can be achieved improving surgical outcome.
