Figure 7: A 59-year old male patient with a history of chronic hypertension who complained of headache and right hemiparesis. MRI examination 12 days after the onset of symptoms showed a left temporal space-occupying lesion. (a, b) Axial T2WI and T1WI: the lesion showed T2 hyperintense core surrounded by hypointense rim [large arrowheads on (a)], T1 hyperintense signal (late subacute hemorrhage). (c, d) Axial diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) map: the lesion displayed hyperintense signal with relative corresponding hypointensity on ADC image reflecting low ADC and restriction of diffusion (ADC = 0.6 × 10-3 mm2/s), still with preservation of the peripheral hypointense rim (hemosiderin, ferritin). Small arrowheads point to small foci of hemorrhage of variable chronological ages. Collectively, the imaging findings are matching with left intracerebral hematoma in late subacute stage with no underlying lesions identified. Follow-up assessment confirmed the diagnosis. |
