HIV infection has become a manageable chronic condition with the advent of antiretroviral therapy (ART), but it remains associated with a range of neurological complications, including cognitive decline, stroke, and other cerebrovascular diseases. Cerebral hemorrhage in HIV-positive individuals, though less frequently reported, has been identified as a potentially under-recognized complication of both the HIV infection itself and its treatment [1]. HIV-associated cerebrovascular disease (HIV-CVD) includes a variety of vascular abnormalities, ranging from small vessel disease to larger arterial occlusions and hemorrhagic events. In recent years, there has been growing recognition of how HIV-related factors, such as immune dysregulation, direct viral invasion of the central nervous system, and antiretroviral medications, may contribute to an increased risk of cerebrovascular events [2]. While much of the focus has been on ischemic strokes in HIV patients, hemorrhagic strokes have also been noted, with a complex interplay of factors that complicate the clinical presentation and management. This case report provides an autopsy examination of an HIV-positive patient who presented with symptoms suggestive of cerebrovascular disease and was ultimately found to have cerebral hemorrhage. The aim is to explore the potential role of HIV in predisposing individuals to such events, the diagnostic challenges that arise, and the broader implications for managing cerebrovascular risk in HIV-infected populations [3, 4]. Through this case, we highlight the importance of early identification, the potential need for more refined screening tools, and the need for vigilant monitoring in patients with HIV at risk for cerebrovascular complications.

Case presentation: A 54-year-old HIV-positive male patient with a known history of poorly controlled HIV infection was found to have suffered a fatal cerebral hemorrhage. The patient had experienced recent neurological symptoms including headache, confusion, and focal neurological deficits. Despite initial management, his condition deteriorated rapidly, leading to death [5]. The autopsy was performed to elucidate the underlying causes of the hemorrhage and to explore any potential HIV-related pathophysiological factors.

Autopsy findings: The autopsy revealed a significant cerebral hemorrhage localized to the left frontal lobe. The hemorrhage was characterized by. There was evidence of endothelial cell injury and disruption of the blood-brain barrier in the vicinity of the hemorrhage.

Histopathological examination: The examination revealed a pattern of cerebral vascular damage, including hypertrophy and proliferation of smooth muscle cells in the small and medium-sized arteries [6]. There was evidence of fibrin deposition and hemosiderin accumulation, indicating chronic hemorrhagic events and repeated bleeding.

Special Stains and immunohistochemistry: Immunohistochemical staining for HIV proteins (p24 antigen) was performed. The results demonstrated the presence of HIV antigens in the brain parenchyma, confirming the involvement of HIV in the pathogenesis. Staining for markers of endothelial dysfunction (e.g., von Willebrand factor) showed evidence of endothelial injury consistent with HIV-related cerebrovascular disease [7].

Discussion

Cerebral hemorrhage in HIV-positive patients is a rare but serious complication that can arise from various mechanisms associated with HIV infection. The autopsy findings in this case highlight several key aspects:

HIV-Associated Cerebrovascular Disease: HIV infection can contribute to cerebrovascular pathology through several mechanisms, including chronic inflammation, endothelial dysfunction, and direct viral invasion [8]. The presence of HIV antigens and the evidence of endothelial injury in this case support the role of HIV in vascular damage. The disruption of the blood-brain barrier and endothelial cell injury are critical factors in the pathogenesis of cerebral hemorrhage. HIV-related inflammatory processes can exacerbate endothelial dysfunction, leading to increased susceptibility to bleeding [9]. The chronic inflammatory response observed in the autopsy is consistent with ongoing HIV infection and its effects on the central nervous system. Inflammation can contribute to vascular damage and enhance the risk of hemorrhagic events.

Management and prevention: Proper management of HIV infection, including effective antiretroviral therapy and regular monitoring of neurological health, is crucial in preventing HIV-related cerebrovascular complications [10]. Early recognition and treatment of HIV-associated cerebrovascular disease can improve patient outcomes and reduce the risk of severe events such as cerebral hemorrhage.

Conclusion

This autopsy case provides valuable insights into the complex relationship between HIV infection and cerebral hemorrhage. The findings underscore the importance of considering HIV-related cerebrovascular disease in patients with neurological symptoms and highlight the need for comprehensive management strategies. Future research should focus on elucidating the precise mechanisms by which HIV contributes to cerebrovascular pathology and developing targeted interventions to mitigate these risks. By advancing our understanding of HIV-related cerebral hemorrhage, we can improve diagnostic, therapeutic, and preventative approaches for affected patients.
