Subdural Hematoma
:
A subdural hematoma (SDH) is a collection of blood between the dura mater and the arachnoid membrane, usually resulting from tearing of bridging veins due to head trauma. It can be acute, subacute, or chronic, depending on the timing of symptom onset after injury.
:
• Headache, confusion, or altered mental status
• Focal neurologic deficits (e.g., weakness, speech disturbances)
• Drowsiness or loss of consciousness
• In infants: bulging fontanelle, irritability, seizures
• In chronic cases (especially in elderly): gradual cognitive decline, gait disturbance, or urinary incontinence — symptoms that may mimic dementia or normal pressure hydrocephalus .
:
• CT scan of the head is the diagnostic test of choice.
• Acute SDH: crescent-shaped, hyperdense (white) lesion.
• Chronic SDH: hypodense (dark) area due to liquefied clot.
• MRI is useful in subacute or isodense hematomas.
• Additional workup may include CBC, coagulation studies (PT, aPTT), and toxicology screening if trauma or abuse is suspected .
Diagnosis:
• Epidural hematoma
• Subarachnoid hemorrhage
• Intracerebral hemorrhage
• Stroke (ischemic)
• Brain tumor or metastasis
• Normal pressure hydrocephalus (especially in older adults) .
:
• Emergency neurosurgical evacuation for large or symptomatic hematomas.
• Burr-hole drainage or craniotomy may be required.
• Medical management for small, stable hematomas:
• Close neurologic monitoring
• Control of intracranial pressure
• Correction of coagulopathy
• Rehabilitation for cognitive and motor deficits after recovery.
-Up:
• Regular neuroimaging to confirm resolution or detect recurrence.
• Monitor for complications such as seizures, rebleeding, or persistent neurologic deficits.
• In elderly or alcoholic patients, preventive measures to reduce fall risk are essential.
