摘要:Congenital cyanotic heart disease patients have increased risk of brain abscess via haematogenous spread.We report the case of a middle aged Lady with Eisenmenger's complex suspected of having a cerebellar abscess clinically and radiologically.But intraoperatively found to have a Pilocytic astrocytoma.This case highlights the difficulty in differentiating between an abscess and tumour at times on imaging.To the best of our knowledge,no association between VSD and Pilocytic astrocytoma has been described in literature.
