Spontaneous intracranial hypotension (SIH) is often associated with chronic subdural hematoma (CSDH). We report two cases of CSDH with a small amount of hematoma, which was not an indication for burr hole drainage; however, each case was assessed as requiring urgent imaging and received an epidural blood patch (EBP). Case 1 was a 66‒year‒old Japanese man who visited our hospital with a complaint of orthostatic headache. Head computed tomography (CT) showed disappearance of the basilar cistern, and an EBP was successfully applied to improve this condition. Case 2 was a 40‒year‒old Japanese man who also complained of an orthostatic headache. Head CT showed downward deviation of the cerebellar tonsil, and an EBP was successfully applied to improve this condition. These cases indicate that an EBP for patients with CSDH combined with SIH is a useful treatment that can improve symptoms while avoiding complications of burr hole drainage when the amount of hematoma is small.
