a seven year-old boy with several painless masses on the ribs and shoulder was referred to our hospital. the masses were so prominent that they prevented the child’s sleep. since the patient had been ridiculed by his friends due to the rib prominences, he had refused to attend school. after clinical and radiological evaluations, the masses were diagnosed as hereditary multiple exostoses of the ...

The object of this paper on tumors of the rib is three-fold. First, to point out that many of them are not metastatic, secondly, that primary malignant tumors are not more frequent than benign tumors, and thirdly, to present some exemplary conditions one should consider in the differential diagnosis of rib tumors. The present review covers the contributions on primary rib tumors through 1953 an...

BACKGROUND To evaluate the incidence of chest wall toxicity after lung stereotactic ablative radiotherapy (SABR) and identify risk factors for the development of rib fracture. METHODS Thirty-nine patients with 49 lesions underwent SABR for primary or metastatic lung tumors using Cyberknife® with tumor tracking systems. Patient characteristics, treatment factors and variables obtained from dos...

Hemangioma of the rib is a rare benign tumor that is often difficult to distinguish from malignant bone tumors. Rib hemangioma often shows bony disruption with a slight cortical disruption, extraosseous lesion, and expanded bone on computed tomography (CT). We report the case of a 68-year-old man with atypical rib hemangioma with a slight cortical disruption and no expanded bone. The tumor show...

An aneurysmal bone cyst (ABC) is a benign tumor of the skeletal system, which most frequently occurs in long bones. An ABC arising from the rib is extremely rare and it is difficult to distinguish from other types of rib tumors. The present study describes an unusual case of a large ABC in the rib of a 17-year-old male. The entity is discussed with particular emphasis on the clinicopathological...

BACKGROUND Hemangiomas are one of the common primary benign tumors of the intraosseous and soft tissue compartments in humans. Vertebral hemangiomas being the most common of all are seen in daily radiological practice. Hemangioma of the rib is rarely seen. CASE REPORT We reported on a case of a rib lesion which had a classic imaging pattern of hemangioma. We highlighted the use of pre-operati...

-We describe a system of computer algorithms that finds the rib cage in chest radiographs. Our algorithms link the dorsal and ventral portions of the rib contours such that each rib is identified and can be displayed individually. In a preliminary application of our system to five adult chest radiographs, about 90)o of the ribs were found, and ca. 15% of the computed rib contours were false. Pa...

Introduction Anatomical variations of human ribs have been well documented [1–3]. Common variations include asymmetric ribs, cervical or lumbar ribs, fusion of rib 1 and 2 and the absence of rib 1 [2, 3]. Unusual variants include fibrous tissue replacing costal cartilage, ribs bifurcated at the sternal insertion, two adjacent ribs articulating at their costal cartilages by a diarthrosis, synart...
