Abstract

LEON CASTELLON, Roberto et al. ^99mTc-MIBI Brain SPECT to discriminate between tumor infiltration and brain abscess in cases of computed tomography and magnetic resonance unconvincing. Case Presentation. Acta Neurol Colomb. [online]. 2016, vol.32, n.1, pp.48-53. ISSN 0120-8748.

The differentiation between brain abscess and brain metastasis in patients with some grade of immune suppression and hematological neoplasm is difficult in some situations. Functional studies like Single-Photon Emission Tomography (SPECT) and Positron Emission Tomography (PET) are useful for this purpose. We present the case of a patient with diagnosis of chronic myelogenous leukemia in blast crisis that a diagnosis of brain abscess was made. The diagnosis had a base in 99mTc - MIBI brain SPECT did not show MIBI uptake and the good treatment response to antibiotics when brain CT scan and MRI were not conclusive. Attending to the SPECT result, chemotherapy was postponed because of probably fatal complications in this patient with brain abscess.

Keywords : Brain abscess; Brain SPECT; ^99mTc - MIBI.
