Intracranial subdural hematomas are rare complications of spinal anesthesia. This paper is a case report of a chronic subdural hematoma (cSDH) developing in a 32-year-old female six months after giving birth by cesarean section using spinal anesthesia. The patient came to the hospital six months after giving birth, complaining of a headache that did not respond to conservative treatments. Her neurological examination was normal. In the computed tomography (CT) and magnetic resonance imaging (MRI) on the left frontoparietal that were performed a prominent subdural hematoma shifting to the right was found. There was no history of trauma. The coagulation tests and MR-angiogram were normal. The patient was treated with burr-hole craniotomy and closed drainage.
