Sickle Cell Disease Presenting as Extradural Hematoma: An Extremely Rare Fatal Crisis.

Sickle cell disease (SCD) is due to a gene mutation in the hemoglobin subunit beta gene, whose polymerization when deoxygenated disrupts the physicochemical properties of red blood cells, triggering pan-cellular activation and pathogenic processes such as hemolysis, vaso-occlusion, and ischemia-reperfusion, culminating in the disease's numerous and severe complication like hemorrhage. This case report highlights spontaneous extradural hematoma in a young adult with SCD as an acute neurological complication.
