[An Uncommon Cerebral Lesion in Computed Tomography].

Area of Science:

• Neurology
• Traumatic Brain Injury
• Neuroimaging

Background:

• The septum pellucidum is a thin partition within the brain.
• Traumatic head injuries can affect various brain structures.
• Accurate diagnosis of brain lesions is critical for patient management.

Observation:

• An 84-year-old male sustained a hematoma of the septum pellucidum following a fall.
• Computed tomography (CT) alone may not reliably differentiate septal lesions in trauma cases without prior imaging.
• The lesion's proximity to the interventricular foramina raises diagnostic challenges.

Findings:

• The case highlights a rare traumatic injury to the septum pellucidum.
• Distinguishing traumatic septal hematomas from other lesions on CT can be difficult.
• Magnetic resonance imaging (MRI) may be necessary for definitive diagnosis.

Implications:

• Understanding the pathomechanisms of head injury involving the septum pellucidum is important.
• Advanced neuroimaging techniques are crucial for accurate diagnosis in complex head trauma.
• This case underscores the need for careful radiological assessment in elderly patients with head injuries.
