75Open Journal of Modern Neurosurgery contrast (83.3%). In most of the patients (85.2%) there were no organisms separated in the culture. 8/54 patients had positive cultures, 7/8 were bacterial and only one (1/8) was fungal. Most patients received antibiotics for 45 days postoperatively in both craniotomy and burr hole groups. When both groups were compared, those operated with craniotomy were found to have a relatively higher length of hospital stay, however, no significant difference was found between both groups. Also, it was found that those operated on with craniotomy had a high cure rate and less recurrence in comparison with burr hole group. Deterioration and death were significantly higher among craniotomy group. Only CT brain was used as the imaging modality of choice for follow-up in both groups for 4 months' duration and it was noted that complete evacuation was significantly higher among craniotomy group while remnants were higher among burr hole group. Conclusion: Brain abscess is still a challenging condition for neurosurgeons in Sudan. The limited number of Sudanese neurosurgeons, neurosurgical centers and diagnostic facilities contributed to delay in diagnosing brain abscess in most patients. It is important to design a strict protocol and precautions for any neurosurgical operation or bedside procedure to prevent infection and subsequent brain abscess development. CT brain with contrast is a good imaging tool for assessing the size, site and stage of brain abscesses. No significant difference between craniotomy or burr hole for clearance from brain abscess in terms of antibiotic used or duration of hospital stay. However, burr hole aspiration is associated with higher rates of recurrences. On the other hand, craniotomy and excision have relatively higher neurologic morbidity postoperative with expectantly higher post-operative hospitalization but no differences in the final outcome. Therefore, the selection of surgical technique should be individualized in each case based on the abscess site size source patient fitness for surgery and neurosurgeon's preference.
