Background: Acute spontaneous subdural hematoma is rare. For patients under 40 years of age, we found only five previous reports. Here, we have presented a sixth case study.
Case description: A 27-year-old male initially presented with a high-intensity headache without any neurological deficits. The brain computed tomography revealed a left frontoparietal lesion, consistent with an acute epidural hematoma. However, the bone window examination showed no fracture, and at surgery, this lesion proved to be an acute subdural hematoma. Additional studies, including cerebral angiography, brain magnetic resonance imaging, and a complete coagulation work-up, were all negative.
Conclusion: This case report and literature review focused on the rarity of acute idiopathic/spontaneous subdural hematomas.
