Abstract: When “common things are common,” the discovery of a subdural hemorrhage in an adult is most likely to be due to trauma. When the subdural hemorrhage is associated with an intraparenchymal hematoma, statistically speaking, the subdural hemorrhage is likely the result of a hypertensive hemorrhage that has ruptured into the subdural space or trauma that resulted from a collapse to the ground following hypertensive intra-axial bleeding. However, “common things” do not always explain the source of a subdural hemorrhage or intraparenchymal hematoma. In this case, an adult woman presented to the hospital obtunded and was diagnosed with a subdural hemorrhage (with mass effect) and intraparenchymal hematoma as the result of a ruptured dural arteriovenous fistula/malformation. This case highlights an unusual source of intracranial bleeding that resulted in death.
