Intracranial hypotension headache complicated by retroclival subdural hematoma: clinical insights and literature review

RcSDH is considered an uncommon complication of SIH, potentially resulting from venous rupture in the retroclival subdural space due to reduced CSF pressure. SIH should be considered in cases of rcSDH. The treatment is typically focused on addressing the underlying etiology, with early diagnosis and timely intervention being essential for achieving favorable outcomes. In cases of severe brainstem compression, hematoma evacuation should be performed in conjunction with EBP.
