Abstract
The clinical course, neuro-imaging features and neuropathologic findings in a child
with para-infectious acute cerebellar swelling are described. Reversible transtentorial
and transforaminal herniations occurred and required emergency posterior fossa decompression
with external ventricular drainage. Neuropathologic examination of a cerebellar biopsy
demonstrated a subacute pathogen-free cerebellitis.
Following neurosurgical intervention and steroid therapy, symptoms and signs resolved
and the patient is well 3 years later. Acute para-infectious cerebellar swelling is
potentially fatal unless recognised and treated early in its evolution.
Key words
