A rare case of acute isodense extradural hematoma was identified in a 30-year-old woman. This study reviews the uncommon computed tomography finding and its underlying pathophysiology.

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Extradural hematomas (EDHs) are typically associated with specific imaging characteristics on computed tomography (CT).
  • Isodense EDHs present a diagnostic challenge due to their similar density to surrounding brain tissue.
  • Understanding the pathophysiology of EDHs is crucial for timely diagnosis and management.

Observation:

  • A 30-year-old female patient presented with an acute isodense extradural hematoma.
  • The computed tomography (CT) scan revealed an unusual isodense appearance of the extradural collection.
  • This finding deviates from the typically hyperdense appearance of acute EDHs.

Findings:

  • The case highlights the possibility of acute isodense extradural hematomas, an uncommon CT finding.

  • Discussion of the pathophysiology provides insights into the mechanisms leading to this specific imaging presentation.
  • Review of the literature emphasizes the rarity and diagnostic considerations of isodense EDHs.

    • Implications:

    • Accurate identification of isodense EDHs on CT is critical for appropriate neurosurgical intervention.
    • This case contributes to the understanding of the spectrum of extradural hematoma imaging findings.
    • Enhanced awareness among radiologists and clinicians may improve diagnostic accuracy for rare EDH presentations.
