In March of 2009, due to headache and behavioural alterations, a cerebral magnetic resonance imaging (MRI) was performed and showed an intracranial extra-axial expansive lesion in the anterior cranial fossa measuring 2,7 x 2,7 x 3,3 cm of transversal, cranial-caudal, and anterior-posterior diameters, respectively, suggestive of olfactory groove meningioma (Figure 1). In March of 2011, within 1 month of allo-HSCT, the meningioma-like lesion was revaluated by MRI and there was a significant increase in its dimensions (5,5 cm x 3,8 cm cranial-caudal and transversal diameters), associated with oedema and mass effect (Figure 1). The meningioma-like lesion was reassessed by MRI, which showed an increase in size (4,5 x 4,8 x 5,9 cm of major diameters), in relation to intratumor hemorrhage, worsening of oedema, and mass effect (Figure 1).
