비골화성 섬유종 및 섬유성 피질골 결손의 새로운 진단적 소견 = New Diagnostic Clues of Non-ossifying Fibroma and Fibrous Cortical Defect

국문 초록 (Abstract)

비골화성 섬유종에서 피질골 관(cortical tract)과 개구관(opening tract), 섬유성 피질골 결손에서 피질골내 병소의 존재는 두 병소의 형태학적인 중요한 특징이며, 이 질환을 진단하는데 중요한 단서로 활용될 수 있으리라 사료된다.

다국어 초록 (Multilingual Abstract)

This study was performed to document the morphologic relationships between non-ossifying fibroma (NOF) and fibrous cortical defect (FCD), as well as to determine any new diagnostic clues. Eighteen patients with 21 NOFs and 14 patients with 15 FCDs found incidentally on radiography were included. The authors prospectively performed CT, MRI, or both on all subjects. The study included size, location, sclerotic property and contour of the periphery, as well as calcification of the matrix of the lesions and the distance from the lesion to the growth plate. The morphologic characteristics were thoroughly reviewed focusing on the presence of the cortical tract in the lesions. The size of the lesion and the distance from the growth plate were not correlated with the patient' age. The presence of the cortical tract was noted in 18(85.7%) out of 21 NOFs, and 10(66.7%) out of 15 FCDs. The presence of the cortical tract was correlated with the longitudinal length of the lesion and the distance from the growth plate. The presence of the cortical tract may be one of the important characteristics in NOF and FCD, and if the diagnosis of bony lesions is obscure by radiologic finding, its exsitence may be a good indicator of diagnosis for NOF or FCD.
