Medical News: A growing body of medical evidence suggests that certain brain tumors may occur in people living with HIV even when their infection is well controlled. A recent medical case and literature review by researchers from the University of Medicine and Pharmacy of Craiova, the “Victor Babes” Hospital of Infectious Diseases and Pulmonology in Craiova, and the Bagdasar-Arseni Clinical Emergency Hospital in Bucharest, Romania, highlights how a type of brain tumor known as astrocytoma can appear in HIV patients despite stable immune function and effective antiviral therapy.
Researchers report a rare case showing that a brain astrocytoma can develop even in HIV patients with
well-controlled infection and stable immunity
A Rare Brain Tumor Appears in a Young HIV Patient
Astrocytomas are tumors that develop from astrocytes, star-shaped support cells found in the brain. These tumors belong to a broader group called gliomas, which are among the most common types of primary brain tumors. They can vary widely in severity, from slow-growing forms to highly aggressive cancers.
Doctors in Romania reported the case of a 34-year-old man living with HIV who began experiencing headaches, facial numbness on one side, and fatigue that slowly worsened over two months. Although his HIV infection had been diagnosed in 2021 and was well controlled with antiretroviral therapy, the neurological symptoms prompted further investigation.
Brain imaging revealed a suspicious lesion in the left temporal region of the brain measuring roughly 3.7 centimeters. MRI scans showed a diffuse infiltrating mass that appeared consistent with a low-grade astrocytoma.
Biopsy Confirms a WHO Grade 2 Astrocytoma
To determine the exact nature of the lesion, surgeons performed a neuronavigation-guided brain biopsy at the Bagdasar-Arseni Clinical Emergency Hospital in Bucharest. Tissue analysis confirmed the tumor was an astrocytoma classified as World Health Organization grade 2.
Detailed molecular testing revealed several important features. The tumor lacked a mutation commonly seen in less aggressive gliomas but showed abnormalities in genes linked to tumor development and progression. The presence of these molecular changes suggests the tumor could potentially behave more aggressively over time despite being classified as a lower-grade tumor.
The patient’s immune system remained relatively strong, with stable CD4 immune cell counts and suppressed HIV viral levels, indicating that the tumor developed even without severe immune suppression.
Why Brain Tumors May Occur in HIV Patients
Scientists still do not fully understand why astrocytomas sometimes occur in people living with HIV. However, several possible explanations have been proposed.
HIV infection can cause long-term inflammation in the brain and immune system. Even when antiviral therapy suppresses the virus, low levels of chronic immune activation may persist. This inflammatory environment may affect brain cells and potentially create conditions that allow tumors to develop.

In addition, viral proteins produced during HIV infection may influence the behavior of brain cells, including astrocytes, altering how they grow and divide.
Another factor is that modern antiretroviral therapy allows people with HIV to live much longer. As survival improves, doctors are increasingly observing cancers that were previously rare in this population.
Diagnosis Can Be Challenging
Brain lesions in people with HIV are often initially suspected to be infections or lymphoma, conditions that occur more frequently in immunocompromised individuals. Because of this, tumors like astrocytomas may sometimes be overlooked or diagnosed later than ideal.

Treatment and Patient Decisions
Doctors recommended surgical removal of the tumor followed by radiotherapy, which is considered standard treatment for many astrocytomas. However, the patient chose a conservative approach and declined surgery and radiation.
Instead, physicians initiated close monitoring with regular clinical evaluations and MRI scans. Early follow-up imaging showed the tumor remained stable in size.
Conclusions
This case highlights that astrocytomas can develop in individuals with well-controlled HIV infection, even when immune function appears stable. It also underscores the importance of considering brain tumors as part of the differential diagnosis in HIV patients presenting with persistent neurological symptoms. Early imaging, biopsy confirmation, and detailed molecular analysis remain essential to guide treatment decisions. Larger studies are still needed to determine whether HIV-related inflammation or other biological factors contribute to the development of gliomas and how best to manage these tumors in people living with HIV.
The study findings were published in the peer reviewed journal: Pathogens.
