Cerebral Myiasis Secondary to Burr Hole Evacuation: A Rare Illustrative Case Report.

Myiasis (maggot infestation) is a condition in which fly maggots feed off and develop in the tissues of living organisms. Most common in tropical and subtropical regions, human myiasis, is prevalent among individuals in close association of domestic animals and those inhabiting the unhygienic conditions. We, hereby, describe a rare case of cerebral myiasis (17th in the world, 3rd in India) that presented to our institution in Eastern India secondary in the operated site of craniotomy and burr hole few years back. Cerebral myiases are exceedingly rare conditions, especially in high-income countries with only 17 previously published cases with the reported mortality as high as 6 out of 7 cases dying of the disease. We additionally also present a compiled review of previous case literatures to highlight the comparative clinical, epidemiological features and outcome of such cases. Although rare, brain myiasis should be a differential diagnosis of surgical wound dehiscence in developing countries where conditions do exist in this country that permit myiasis. This differential diagnosis should be remembered, particularly when the classic signs of inflammation are not present.
