Acute Spontaneous Subdural Hematoma in a Middle-Aged Adult: Case Report and Review of the Literature.
Acute spontaneous subdural hematomas (ASSDH) occur by a variety of pathological processes and are less common than trauma-related acute subdural hematomas (SDH). Both types are usually seen in the elderly, and only 22 cases of ASSDH in patients aged < 40 years have been reported in the medical literature. ⋯ Given the rarity of SDH in nonelderly patients, this case suggests a broader differential diagnosis for nontraumatic headaches to include arterial and even neoplastic origins. Our literature review confirms the paucity of reported incidences of ASSDH, yet reminds medical providers to closely monitor for developing neurological symptoms and initiate prompt medical intervention when necessary.

ReviewAcute subdural hematoma from bridging vein rupture: a potential mechanism for growth.
Most acute subdural hematomas (ASDHs) develop after rupture of a bridging vein or veins. The anatomy of the bridging vein predisposes to its tearing within the border cell layer of the dura mater. Thus, the subdural hematoma actually forms within the dura. ⋯ Thus, the ASDH enlarges via a positive feedback mechanism. Enlargement of an ASDH would cease as blood within the hematoma cavity coagulates. This would stop the dissection of the dural border cell layer, and pressure within the hematoma cavity would equalize with that in the torn bridging vein or veins.

Sphenoid and Subdural Hemorrhage as a Presenting Sign of Ruptured Clinoid Aneurysm.
Aneurysm rupture presenting as an isolated or pure subdural hematoma (SDH) without subarachnoid hemorrhage is an extremely rare radiographic presentation. We present a case of a ruptured internal carotid artery aneurysm with a pure SDH and concurrent sphenoid sinus hemorrhage. ⋯ Acute subdural hematoma may be due to a ruptured clinoid carotid aneurysm. Acute hemorrhage into the sphenoid sinus can be an important clue.

ReviewSurgical management of traumatic acute subdural hematoma in adults: a review.
Traumatic acute subdural hematoma (ASDH) is a major clinical entity in traumatic brain injury (TBI). It acts as a space occupying lesion to increase intracranial pressure, and is often complicated by co-existing lesions, and is modified by cerebral blood flow (CBF) changes, coagulopathy, and delayed hematomas. Because of its complicated pathophysiology, the mortality of ASDH is still remaining high. ⋯ Since Glasgow Coma Scale (GCS) scores, age, papillary reaction, and computed tomographic findings are strongly correlated to outcome, each factor has been investigated as an indicator of salvage ability. None of them, however, has been defined as such one. In future studies, epidemiological changes as population ages, management of delayed pathophysiology, superiority of each surgical procedures, and salvage ability should be addressed.

Acute subdural hematoma without subarachnoid hemorrhage or intraparenchymal hematoma is rare. ⋯ Ruptured intracranial aneurysm should be considered as a cause of nontraumatic subdural hematoma. Immediate subdural hematoma removal after aneurysm coiling can be performed in such patients, even those in poor neurological condition.
