What is subdural hygroma?
Subdural hygroma consists of a cerebrospinal fluid-like subdural fluid collection with a low oncotic pressure in comparison with venous blood. Its etiology and pathophysiology, which may be different from other subdural fluid collections, are reviewed.
What causes hygroma in the brain?
Intracranial Hematoma or Hygroma An intracranial hematoma is a collection of blood within the skull, most commonly caused by rupture of a blood vessel within the brain or from trauma, such as a car accident or fall. The blood collection can be within the brain tissue or underneath the skull pressing on the brain.
What causes chronic subdural hematoma?
A subdural hematoma develops when bridging veins tear and leak blood. These are the tiny veins that run between the dura and surface of the brain. This is usually the result of a head injury. A collection of blood then forms over the surface of the brain.
Can you recover from chronic subdural hematoma?
In some cases, a subdural haematoma can cause damage to the brain that requires further care and recovery time. How long it takes to recover varies from person to person. Some people may feel better within a few weeks or months, while others may never make a full recovery even after many years.
Can hygroma be cured?
Your veterinarian may recommend draining the hygroma with a needle or treating your dog with cold laser therapy (also called photobiomodulation) to speed healing. Infected hygromas must be treated with antibiotics to resolve the infection.
What is subdural hygroma on CT scan?
Subdural hygroma is a cerebrospinal fluid accumulation in the subdural space. It is an epiphenomenon of head injury. CT is the preferred diagnostic imaging modality. Differential diagnosis has to be made with chronic subdural hematoma, and atrophy with enlargement of the subarachnoid space.
How is a differential diagnosis of subdural hygroma (SDH) made?
Differential diagnosis has to be made with chronic subdural hematoma, and atrophy with enlargement of the subarachnoid space. As time … Subdural hygroma is a cerebrospinal fluid accumulation in the subdural space. It is an epiphenomenon of head injury. CT is the preferred diagnostic imaging modality.
What causes acute subdural hygroma?
An acute subdural hygroma results from the acute accumulation of CSF within the dural border cell layer. This can result from an acute tear in both the arachnoid and the dural border cell layer, resulting in communication of these two spaces.
What is the role of CT in the diagnosis of subdural hemorrhage?
In the vast majority of cases, CT scans are sufficient to make the diagnosis and manage these patients. Contrast is sometimes helpful if there is the concern of subdural empyema, of the presence of a small isodense subdural, or to try and distinguish enlargement of the extra-axial CSF space from a chronic subdural hematoma.
