摘要：
Introduction. - The osteoid osteoma is a major bone benign tumors in children. It is more common in boys. The femoral and tibial locations account for 50% of cases. 'Clinically, it is revealed by nocturnal pain relieved by aspirin. The pain may precede by several months the radiographic abnormality. The purpose of our work is to elucidate the contribution of SPECT/CT in addition to the planar bone scintigraphy in the diagnosis and treatment of osteoid osteoma about two cases. Case report. - Clinical case No. 1: a 10-year-old child who presented a limp nocturnal pain in the left hip evolving for 4 months. The radiograph of the pelvis showed bone condensation subtrochanteric left femur. SPECT/CT showed an image for an osteoid osteoma. Surgical resection of the home revealed in the histological study an osteoid osteoma of the left femoral neck. The evolution was marked by an immediate pain relief and full recovery of the left lower limb mobility. Clinical case No. 2: an 11-year-old child who had a limp nocturnal pain at the upper end of the left femur evolving for 2 months. The pain was paroxysmal, relieved by salicylates. The X-ray of the pelvis showed a metaphyseal image with peripheral condensation and thickening of the cortex. SPECT/CT showed an image for an osteoid osteoma. The intervention was a tumor excision resection. Histopathological examination revealed a small nidus consistent with an osteoid osteoma. The evolution was marked by an immediate pain relief and normalization of the mobility of the left lower limb. Discussion. - The SPECT/CT can increase the sensitivity and specificity of planar bone scintigraphy. It confirms the location of osteoid osteoma and defines its anatomical relationships in order to optimize surgical management. Conclusion. - The SPECT/CT contributes significantly to the diagnosis of osteoid osteoma when radiological images are atypical or unusual clinical expression. (C) 2013 Elsevier Masson SAS.
