Head CT on admission shows multiple annular nodules in the left thalamus, and the edema is obvious (A). The chest CT shows a space-occupying lesion in the cavity in the upper lobe of the right lung (B). The head MRI on May 12 showed that scattered multiple signals can be seen in the bilateral cerebral hemispheres, thalamus, and brainstem, which were low signal on the T1 weighted image and high signal on the T2 weighted image and diffusion-weighted imaging (C-E). Magnetic Resonance Spectroscopy (left thalamus) showed that the Cho peak, Cr peak, and NAA peak decreased, the Cho/Cr ratio was 0.709, the Cho/NAA ratio was 0.847, and the LL peak increased significantly (F). Brain abscess was significantly enhanced (G-I).

On the day of admission, the patient had difficulty breathing and was given mechanical ventilation with tracheal intubation (Figure 1).
CT after 2 months of treatment. The size of the lesion and the degree of edema improved significantly (A). The patient's upper right pneumonia is better than before (B). The patient MRI in August 2021 showed that the abscess was significantly absorbed and improved (C-F).

The 3-month follow-up head MRI showed that the brain abscess had basically disappeared (Figure 2).
