Brain biopsy in patients presenting with subacute encephalopathyis never
straightforward and only undertaken when a 'treatable condition' is a realistic
possibility. This 63 year old right handed, immunocompetent Caucasian woman
presented with an 8 month history of rapidly progressive right-sided hearing
impairment, a 4 month history of intermittent headaches, tinnitus, 'dizziness',
dysphagia, nausea and vomiting, with the subsequent evolution of progressive gait
ataxia and a subacute global encephalopathy. The possibility of CJD was raised.
Brain biopsy was carried out. Western blot for prion protein was negative. She
died 9 days later and autopsy brain examination confirmed widespread subacute
infarction due to an EBV positive atypical NK/T-cell infiltrate with positivity
for CD3, CD56, granzyme B, perforin and EBER with absence of CD4, CD5 and CD8
expression. Molecular studies for T-cell clonality were attempted but failed due
to insufficient DNA quality. Serology was consistent with past EBV infection (EBV
VCA and EBNA IgG Positive). There was no evidence of disease outside the CNS.
Primary central nervous system NK/T-cell lymphoma is extremely rare. The rare
reported cases all present with a discrete intracranial mass, unlike the diffuse
infiltrative pattern in this case. Whilst the diffuse interstitial pattern is
reminiscent of chronic active EBV infection (CAEBV) seen in other organ systems
such as the liver and bone marrow, the clinical presentation and epidemiologic
profile are not typical for CAEBV.
