Nontraumatic bilateral subdural hematoma: Case report.

A subdural hematoma (SDH) is a type of bleeding in which a collection of blood gathers between the inner layer of the dura mater and the arachnoid mater of the meninges surrounding the brain. Although most cases reported of subdural hematoma are due to traumatic brain injury, to the best of our knowledge this is a rare case of nontraumatic subdural hematoma. A 31 year-old-Male presented to the emergency department with a severe headache for 3 weeks, with the presence of oculomotor disorders. There is no history of major trauma, minor trauma or fights. Also, no history of hypertension, or Haematological diseases. Magnetic resonance imaging (MRI) showed bilateral subdural hematoma. The right-sided hematoma was treated conservatively and the Left-sided was treated by surgery. Follow-up for three months revealed no recurrence. Nontraumatic subdural hematoma is one of the challenging cases that neurosurgeons face. We presented a patient with idiopathic spontaneous subdural hematoma. Computed tomography (CT) is the first step for diagnosis and Magnetic resonance imaging (MRI) is considered an excellent imaging investigation to evaluate such patients. Symptomatic subdural hematomas require an emergent treatment by identifying and controlling sites of bleeding conservatively or by surgery. Subdural hematoma with no history of trauma should be treated emergently and evaluated strictly. Follow-up is essential in patients with neural symptoms. Massive symptomatic subdural hematoma (SDH) should be treated with surgery to control the bleeding.
