Abstract
In this study, 30 patients complaining of benign bone tumor and tumor like klesions are presented to the MDCT unit in Minia university hospital .Many of these tumors are discovered accidentally
Once a skeletal abnormality has been detected, the next objective of imaging is to attempt to characterize the lesion and, in doing so, indicate an appropriate differential diagnosis to the referring clinician. At this stage important maxims that should be appreciated include not overrtreating a benign lesion, not under-treating a malignant lesion and not misdirecting the approach to biopsy that might prejudice subsequent surgical management
In drawing up a differential diagnosis for a particular case the radiologist must first have knowledge of the different pathologies that may arise in the musculoskeletal system. While an understanding of the microscopic features is not required, it is clear that an entity will not appear in the differential diagnosis if the radiologist involved is unaware of its existence.
The vast majority of primary bone tumors are benign and since many are non-symptomatic they remain undetected or are detected only incidentally at radiographic examinations for other reasons. The true incidence of benign bone tumors has therefore been difficult to determine
Bone lesions are frequently missed or overlooked on the initial radiograph. The approach to the radiographic diagnosis of bone tumors consists of analyzing the lesion in an organized fashion, with attention paid to several specific radiographic features. While these features were originally described
can also be applied to computed tomographic images. This reflects the fact that both are radiographic techniques relying on the attenuation of an X-ray source.
