Managing the "big black brain" in low resource setting: A case report of early outcome after hinge craniotomy.

BACKGROUND

The big black brain (BBB) phenomenon is described as an infant's response to an acute subdural hematoma (SDH). It is characterized by hypodensity and swelling of the supratentorial compartment as a whole. Numerous factors may contribute to the formation of the BBB. Due to its high morbidity and mortality, the management of BBB is still debatable. In this report, we describe a 2-month-old boy who had bilateral hemispheric hypodensity and underwent hinge craniotomy.

CASE DESCRIPTION: The patient was referred to our hospital with decreased consciousness. The patient had a history of seizures and cardiopulmonary arrest. There is no history of trauma. The computed tomography revealed a subacute SDH on the left parietal and occipital lobe along with hypodensity in both hemispheres with preservation of posterior fossa, consistent with hemispheric hypodensity. We performed a hinge craniotomy for the emergency procedure and evacuated only the hemisphere with the bleeding side. The patient cried spontaneously 24 hours after the procedure and was discharged six days later.

CONCLUSION

Early outcomes of hinge craniotomy as an alternative procedure for treating the BBB were positive. However, long-term outcomes, particularly the infant's development, should be monitored.
