Abstract:
A case of traumatic orbital encephalocele following a "blow-in" fracture is presented. Computed tomography (CT) and magnetic resonance imaging (MRI) findings are shown. Although CT was useful for identifying the orbital roof fracture, bone fragments and soft tissue abnormalities, MRI was more sensitive to brain herniation and an intraorbital haematoma.
Insights
A traumatic orbital encephalocele case is detailed, highlighting imaging techniques. Magnetic resonance imaging (MRI) proved more sensitive than computed tomography (CT) for detecting brain herniation and intraorbital hematoma.
Area of Science:
- Neurosurgery
- Ophthalmology
- Radiology
Background:
- Orbital encephaloceles are rare, often resulting from congenital defects or trauma.
- Traumatic orbital encephaloceles, particularly from 'blow-in' fractures, present unique diagnostic challenges.
Observation:
- This case report details a traumatic orbital encephalocele secondary to a 'blow-in' orbital roof fracture.
- The patient's presentation involved complex orbital trauma requiring advanced imaging evaluation.
Findings:
- Computed tomography (CT) effectively identified the orbital roof fracture, bone fragments, and associated soft tissue abnormalities.
- Magnetic resonance imaging (MRI) demonstrated superior sensitivity in detecting brain herniation and intraorbital hematoma, crucial for surgical planning.
Implications:
- Accurate diagnosis of orbital encephaloceles relies on a combination of advanced imaging modalities.
- MRI is essential for evaluating the extent of brain herniation and associated vascular complications in traumatic orbital injuries.
