It is understood that subdural hematoma is the result of rupture in bridging veins (mostly due to head trauma) and hemorrhage between dura matter and arachnoid, leading to subdural hematoma, or rupture of small cortical atreries and hemorrhage into the space between dura matter and arachnoid, leading to subdural hematoma or intracranial hypotension (mostly due to lumbar punctue) and traction of bridging veins which leads to subdural hematoma. Genes involved in the pathogenesis of subdural hematoma include ADPKD, osteogenesis imperfecta, fabry's disease, mucopolysaccharidosis IIIB, and type B Niemann–Pick disease. On gross pathology, crescentic shape blood in the subdural potential space are characteristic findings of subdural hematoma. On microscopic histopathological analysis, blood in subdural space is characteristic findings of subdural hematoma.
