Bone cystic angiomatosis is a disease with only 200 cases described, based on angiomatous nonmalignant proliferation, in bone tissue and viscera. It focuses on pelvis, long bones and scapular waist. Clinical evolution ranges from self-limiting forms to massive aggressive osteolysis (Gorham-Stout).Its diagnosis is of exclusion, with nonspecific clinical, radiological (lytic images) and histopathological findings. Our study is based on the clinical case of a 14-year-old man diagnosed with bone cystic angiomatosis, with disseminated bone involvement, who came to our center for pain and functional impotence in the right hip, diagnosing a pertrochanteric fracture. It was operated by open reduction and osteosynthesis with four-hole VERSA sliding plate screw. An allogeneic graft of cancellous bone was used from femoral head. The evolution was satisfactory, with ambulation at full load per month without requiring analgesic medication and control X-ray at eight months that showed signs of complete integration of the graft. The analgesic pain scale (visual analogue scale) showed a score of 2/10 per month. There is controversy regarding the treatment of these fractures by osteosynthesis with bone graft. We are facing a case without serious clinical criteria, but with multiple foci of osteolysis. It was decided not to intervene prophylactically the contraleteral hip, since it is asymptomatic and there are different patterns of evolution described in the literature and risks in surgery.
