Abstract

Introduction: Bone Island is an asymptomatic lesion located in cancellous bone. Can be encountered in many places on the skeleton is rarely observed in the vertebral bodies. In this case giant cortical bone island was located in L2 vertebral body. Case52 years old male patient was consulted from urology clinic due to incidentally discovered large sclerotic lesion at L2 vertebral body on urinary x-ray imaging. CT and MRI demonstrated a large cortical bone island filling the left half of the L2 vertebral body. Since lesion was completely asymptomatic, no further diagnostic evaluation or treatment was made. After 2 years follow up, no sign of progression was noted. Discussion: Bone island is an asymptomatic benign tumoral lesion which characterized by formation of cortical bone in cancellous bone usually involves long bone epiphysis and metaphyses and pelvis. Vertebral body is a rare location for bone islands. Care should be taken for enlarging and scintigraphically active lesions.
