A 14 year old boy, said to have had multiple transfusions during infancy, was brought to the hospital for complaints of pain over right thigh for one week duration. MRI reveals multiple osteolytic lesions with enhancing hyperintense bone marrow lesions over iliac bones, right acetabulum and lumbar vertebral bodies and enlarged para-aortic, iliac and inguinal lymph nodes. CT of the whole body revealed osteolytic lesions on skull, mandible, right scapula, head of both humeri, L1 and L4 vertebrae, 5(th) and 10(th) ribs, both acetabulum and ala of sacrum along with enlargement of cervical, axillary and mesenteric, iliac and inguinal nodes. HIV ELISA was positive. Viral load was 141,700 copies/ml. CD4 count was 226 cells/mm(3). Multiple biopsy from the lesions and bone marrow revealed no evidence of tuberculosis and malignancy. Now the boy is on ART (ZDV + 3TC + EFV) since August 2013. His CD4 count improved and viral load became undetectable and he gained weight within 5 months of ART. Due to the rarity of its presentation, this case report is being reported.
