In research on intracranial vasculopathy in HIV patients by Thawani et al., the authors suggested that arteriopathies causing structural arterial disease in patients with HIV may result from opportunistic infection including viral (varicella-zoster virus, Epstein–Barr virus, hepatitis B virus, or cytomegalovirus) or bacterial (toxoplasmosis, pneumocystis, salmonella, and several other mycobacteria) entities.[1] Multi-factors may cause vascular inflammation by HIV-induced immunologic abnormalities and exposure to a variety of xenoantigens, such as HIV itself, other infectious agents, and drugs.[2] Lefeuvre et al. reported a case of intracranial arterial dissection in a HIV patient.[3] They also reviewed its histology which showed marked intimal proliferation and disruption of the internal elastic lamina. The new vessel proliferation observed in the adventitia may be similar to vasa vasorum rupture in large arteries. The new vessels seen in the adventitial layer of this patient's arteries may represent proliferating vasa vasorum. As the research reported above, we can presume that HIV may possibly induce vasculopathy by unknown mechanism. However, there is still no case about HIV with renal vein aneurysm reported. Even in our case, we did not examine the HIV infection, but the patient was still in healthy condition without any symptom/sign of immunodeficiency. Although HIV was still an important health problems in Taiwan, it is hard to do the examination of HIV due to human right and culture reason. However, it definitely provided a new aspect about renal vein aneurysm.
