Acute subdural hematomas are frequently seen in brain trauma−injured patients. However, spontaneous subdural hematomas are uncommon, especially those localized in the posterior fossa, where fewer than 10 case reports have been described in the medical literature. We describe a patient who suddenly had a headache and progressed rapidly to coma and signs of brainstem compression. She was diagnosed with posterior fossa subdural hematoma after image examinations that were endorsed by surgical findings. A posterior fossa craniectomy was performed and was associated with blood drainage. The patient had a great outcome, with no neurologic deficits at hospital discharge and the 1-year follow-up. •Only 6 case reports have described spontaneous posterior fossa hematoma.•Only 2 patients have survived surgical treatment according to case reports.•Our patient had no history or signs of trauma, and a prompt investigation and diagnosis were performed.•With proper surgical treatment, she had a successful neurologic and clinical outcome through the 1-year follow-up.
