Subdural and epidural hematomas are both types of traumatic brain injuries that involve bleeding inside the skull. These two conditions can be differentiated on a CT scan based on their location, shape, and appearance. Subdural hematomas typically occur between the dura mater (the outermost layer of the brain) and the arachnoid mater (the middle layer), while epidural hematomas occur between the dura mater and the skull. On a CT scan, subdural hematomas often appear crescent-shaped and can cross suture lines, while epidural hematomas are typically lens-shaped and do not cross suture lines. Additionally, subdural hematomas are usually associated with more diffuse brain injury and can cause midline shift, while epidural hematomas are more localized and may not cause midline shift. In cases of uncertainty, other imaging modalities such as MRI or angiography may be used to confirm the diagnosis. Understanding the differences between subdural and epidural hematomas on CT scans is crucial for appropriate management and treatment of patients with traumatic brain injuries.
What does a hematoma look like on CT scan?
On the CT imaging, the hematoma typically looks like a lenticular, ellipsoid, perihepatic collection with a density that on the non-enhanced exam depends on the “age” of the hematoma. Acute hematomas are typically hyperdense (40-60 HU), due to the high protein content [8].
What does a subdural hematoma look like on a CT scan?
Post-traumatic acute subdural hematomas generally appear hyperdense on a computed tomography scan. In the hyperacute stage, a subdural hematoma in rare cases appears heterogeneous with isodense images. This can pose a diagnostic problem and compromise patient care.
How can you tell the difference between subdural hematomas?
Patients with an epidural hematoma can remain conscious with minimal symptoms, can become drowsy, or can progress to a coma immediately following their injury based on the size of the hematoma. A subdural hematoma occurs when the bleeding exists inside the dura, but still outside the brain.
What classic CT findings appear on a head CT for a subdural hematoma?
The classic appearance of an acute subdural hematoma is a crescent-shaped homogeneously hyperdense extra-axial collection that spreads diffusely over the affected hemisphere. As the clot starts to retract the density increases typically to >50-60 HU and is thus hyperdense relative to the cortex 4.
How much can you sue for personal injury in Texas?
