Brain and lung CT examination of the patients with AIDS-associated T. marneffei central nervous system infection. a Bilateral lateral ventriculomegaly: the bilateral lateral ventricles were dilated, and the brain parenchyma was slightly compressed bilaterally (arrow). b Patchy low-density shadow in the right cerebellar hemisphere in contrast enhanced CT: flaky low-density shadow on the right cerebellar hemisphere with unclear boundaries; the lesion was approximately 2 cm in size. There was no enhancement of the lesions after the use of contrast media (arrow). c Multiple intracranial infectious lesions with cerebral edema: parenchymal swelling in the left frontal lobe, insula and basal ganglia, cerebral sulcus thinning, extensive edema in the white matter parenchyma of the frontal lobe, showing low density (arrow). d Left pulmonary nodules with voids: high-density nodules in the dorsal segment of the left lower lobe, approximately 2 cm in diameter, with unclear boundaries and a cavity within the lesion (arrow). e Interstitial pneumonia: diffuse ground-glass opacity of bilateral lungs, patchy high-density shadow of the subpleural area in the posterior segment of apex of left lung, with thickening of the adjacent pleura
