Overview
The CT scan is the gold standard test for the diagnosis of epidural hematoma. Among patients with head trauma CT scan is indicated for detecting epidural hematoma and other kind of intracranial hemorrhages in patients with: age > 60 years, glasgow Coma Scale under 15, Headache, Vomiting, Loss of consciousness, Amnesia, alcohol or drug intoxication. Screening for cervical spinal hematoma by CT scan is recommended among patients with acute onset of hemiparesis, specially when they are associated with neck pain.
Diagnostic Study of Choice
Study of choice
The CT scan is the gold standard test for the diagnosis of epidural hematoma.
Diagnostic results
The following finding(s) on performing CT scan are confirmatory for epidural hematoma:
- Bi-convex (or lentiform) shaped hematoma in epidural space which can cross the dural reflections unlike a subdural hematoma but it does not cross skull's suture lines where the dura tightly adheres to the adjacent skull.
- Depending on the size of hematoma, secondary features of mass effect may be present which include:
- Midline shift
- Subfalcine herniation
- Uncal herniation
Sequence of Diagnostic Studies
The [name of investigation] should be performed when:
- The patient presented with symptoms/signs 1, 2, and 3 as the first step of diagnosis.
- A positive [test] is detected in the patient, to confirm the diagnosis.
Diagnostic Criteria
- Here you should describe the details of the diagnostic criteria.
- Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for the diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
- Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
- Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
- Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.
- To view an example (endocarditis diagnostic criteria), click here
- If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
- You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
- [Disease name] is mainly diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].
- There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].
- [Disease name] may be diagnosed at any time if one or more of the following criteria are met:
- Criteria 1
- Criteria 2
- Criteria 3
IF there are clear, established diagnostic criteria:
- The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
- The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].
- The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].
IF there are no established diagnostic criteria:
- There are no established criteria for the diagnosis of [disease name].
Indication of CT scan in diagnosis of epidural hematoma
- Among patients with head trauma CT scan is indicated for detecting epidural hematoma and other kind of intracranial hemorrhages in patients with:[1][2][3][4]
- Age > 60 years
- Glasgow Coma Scale under 15
- Headache
- Vomiting
- Loss of consciousness
- Amnesia
- Alcohol or drug intoxication
- Screening for cervical spinal hematoma by CT scan is recommended among patients with acute onset of hemiparesis, specially when they are associated with neck pain.
