Acute isodense epidural hematoma on computed tomography.

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Computed tomography (CT) is a cornerstone in diagnosing craniocerebral injuries.
• Acute epidural hematomas typically present with a characteristic lenticular (lens-shaped) hyperdensity on CT, often over the cerebral convexity.

Observation:

• This case report details an unusual presentation of an acute epidural hematoma.
• The hematoma exhibited an isodense appearance, closely matching the density of the surrounding brain tissue on CT imaging.

Findings:

• The primary finding is an acute epidural hematoma that lacks the typical hyperdense appearance on CT.
• Isodensity with brain tissue can mask the presence of epidural hematomas, complicating diagnosis.

Implications:

• This case underscores the importance of considering atypical CT findings in diagnosing epidural hematomas.
• Radiologists and clinicians must be aware of isodense epidural hematomas to avoid diagnostic delays and ensure timely intervention.
• Further vigilance and consideration of differential diagnoses are crucial when CT findings are equivocal for traumatic brain injury.
