Figure 1 Computed tomography scan viewed in the lung window. A: Infiltrates and ground-glass opacities on both lungs were seen 1 mo before admission; B: On admission day, an improvement was seen in those changes after outpatient treatment.

Figure 2 Magnetic resonance T2-weighted imaging. A: Sagittal scan showed a space-occupying a lesion with slightly hyperintense signal at the right cerebellopontine angle, cerebellar tonsil, and medulla oblongata without a clear boundary; B: Sagittal scan showing a space-occupying lesion with inhomogeneous enhancement; C: Transverse image showing a space-occupying lesion with slightly hyperintense signal at the right cerebellopontine angle and the cerebellar tonsil. White and black arrows indicate the space-occupying lesion of the cerebellum and brainstem.
