Figure 1: Brain computed tomography (CT) and magnetic resonance imaging (MRI) of the patient with intracranial GS. (a) CT scan of the brain revealed an irregular high-density occupying lesion in the frontoparietal region. (b) T1-weighted MRI showed the irregular mass lesion appeared as iso-T1 signal. (c) T2-weighted MRI showed the tumor appeared as iso-T2signal. (d) Contrast-enhanced MRI revealed the tumor was visible inhomogeneous enhancement, an irregular long-T1 lamellar signal was found in the lesion. It was approximately 4.2x4.5x5.2 cm in size
