Diffusionsvaegtet magnetisk resonans-skanning kan skelne abscesser fra tumorer i hjernen
Sammanfattning
Early diagnosis of cerebral abscess, which is decisive for the prognosis, is often complicated by the lack of clinical signs. Conventional computed tomography and magnetic resonance imaging cannot always differentiate a cystic or necrotic tumor from an abscess. An abscess is therefore sometimes misdiagnosed as e.g. a glioblastoma or metastasis. Unfortunately, this is sometimes seen at our department and could maybe have been prevented. Diffusion-weighted imaging and apparent diffusion coefficient facilitate differentiation between cerebral tumor and abscess with a sensitivity of 95.2% (76.2-99.9%) and a specificity of 95.7% (78.1-99.9%).
