MRI examinations of a 5-year-old post-allogenic HSCT patient presenting with convulsions. a, b and c Initial MRI examination: axial T1WI (a), axial T2WI (b), and post-contrast axial T1WI (c) sequences revealed left temporal intra-axial SOL showing high T1WI signal, heterogenous T2WI signal, and heterogeneous post-contrast avid enhancement with related mild meningeal enhancement. Subsequent mass effect is noted evident as effacing the overlying sulci, compressing the ipsilateral temporal horn. The patient was initially diagnosed as a case of left temporal intra-parenchymal hematoma. Marked deterioration of the patient required follow-up MRI examination after 3 weeks. d, e, and f Axial T1WI (d), axial T2WI (e), and post-contrast axial T1WI (f) sequences revealed a rather stationary course of the previously noted SOL with markedly evident related meningeal enhancement and newly developed right temporal lobe meningeal enhancement (blue arrow). Pathology after temporal lobectomy revealed relapsed B cell non-Hodgkin lymphoma
