Osteonecrosis of the femoral head in HIV-infected patient
This is a cinematic rendering (cVRT) CT image of a 49-year-old male with a history of HIV infection and antiretroviral (ART) therapy for five years before this CT scan. Four years prior to this CT scan, he also had a history of T cell lymphoma and four-stage CHOP chemotherapy, consisting of: Cyclophosphamide, Doxorubicin Hydrochloride (Hydroxydaunomycin), Vincristine Sulfate (Oncovin) & Prednisone. On this CT scan, we see that the right femoral head has lost its sphericity with subchondral cystic changes. Subtle subchondral irregular, linear hypointensity seen parallel to the articular surface. Pelvic bone osteoporosis is also visible. A 64-slice CT scanner was used, with the thickness parameter set to 1 mm.
