Favourable Outcome in a 33-Year-Old Female with Acute Haemorrhagic Leukoencephalitis.

Background: Acute haemorrhagic leukoencephalitis (AHLE) is a rare and rapidly fatal disease of unknown aetiology. There is a paucity of literature on the presentation and management of this rare disease.

Case Description: We report the case of a 33-year-old female presenting with headache and left-sided apraxia. Imaging revealed a right-sided white matter lesion with extensive cytotoxic oedema. Pathology was suggestive of AHLE. She underwent an open excisional biopsy and was treated with high-dose corticosteroids. Three months since symptom onset she remains clinically well with resolving apraxia and radiological appearance.

Conclusion: This case may represent a milder spectrum of AHLE, which responded favourably to corticosteroids.
