Computed tomography in acute haemorrhagic leukoencephalitis

Area of Science:

• Neurology
• Neuroimaging
• Pathology

Background:

• Acute haemorrhagic leukoencephalitis (AHLE) is a rare, severe demyelinating disease.
• Early diagnosis is crucial for appropriate management and improved patient outcomes.

Observation:

• Three patients with biopsy-proven AHLE were analyzed.
• All presented with acute onset of focal neurological deficits, fever, and elevated white blood cell count.
• Two patients experienced impaired consciousness.

Findings:

• Computed tomography (CT) revealed hypodense white matter lesions in the cerebral hemispheres.
• One case showed central enhancement within the hypodense areas on CT.
• The characteristic clinical presentation and CT findings are highly suggestive of AHLE.

Implications:

• The study highlights the importance of integrating clinical and neuroimaging findings for diagnosing AHLE.
• Prompt recognition can guide timely therapeutic interventions.
• Further research into AHLE pathogenesis and treatment is warranted.
