Abstract: The number of tuberculosis patients in China has increased year by year, AIDS patients with low immunity are more likely to be complicated with tuberculosis, which can worsen their condition and increase the likelihood of mortality. In recent years, there has been a rise in cases of intracranial tuberculosis among HIV patients. These cases are typically diagnosed using immunological tests and imaging techniques. Among them, imaging diagnosis is the first choice for diagnosis of AIDS complicated with intracranial tuberculosis. Through early diagnosis and timely treatment, HIV infection and its complications can be improved. AIDS complicated with intracranial tuberculosis includes, tuberculoma of the brain, and tuberculous brain abscess. Imaging results for HIV intracranial TB are closely linked to the patient's CD4⁺ T lymphocyte count.When the infected patient has a CD4⁺ T lymphocyte count below 100 cells/μl, the intracranial TB lesions are predominantly subcortical parenchymal lesions; each type of intracranial tuberculosis has characteristic imaging presentations at different stages. Complications of AIDS complicated with intracranial tuberculosis usually include hydrocephalus, vasculitis, and cerebral infarction. When the CD4⁺ T lymphocyte count in infected patients is above 100 cells/μl, there is no clear distinction between the presentation of intracranial TB and that caused by simple infection. The aim of this article is to review the advances in diagnostic imaging of intracranial tuberculosis infection in AIDS and to improve the diagnosis of this disease.
