body skeletal scintigraphy performed with 20 mCi (740 Mega Becquerel) of Technetium-99m Methylene DiphosPhonate (MDP) revealed diffusely increased tracer uptake over body of sternum and manubriosternal junction suggestive of neoplastic process. A focal area of benign uptake was also seen over left 2nd costochondral junction (Fig. 3). Contrast enhanced CT study revealed mixed sclerotic and lytic...

Background Sternal fracture is uncommon injury following blunt chest trauma. They are usually caused by direct blunt trauma to the sternum, or most frequently car accident, including steering wheel direct blunt trauma to the sternum. Sternal fracture should be regarded as a hallmark of severe multiple injuries until proven otherwise. The purpose of this study was to describe general features co...

Sternum is formed from bilateral mesenchymatous condensations, sternal plates, which begin in the dorsolateral region of body wall. These plates undergo chondrification, move ventrally towards each other from both sides, and they eventually fuse together across the midline in a craniocaudal direction. Mesosternum (body) ossifies from 4 sternebrae. Sternal foramen, of varying size and form, may ...

A 59-year-old man who underwent radiation therapy (41 Gy) to the mediastinum through the anterior chest for Hodgkin's disease presented with a painful anterior chest wall tumor 18 years later. The tumor originated from the left parasternal region and was excised with the sternum. Chest wall reconstruction was performed. The tumor measured 45 x 45 mm and invaded the sternum. The pathologic diagn...

Background/Introduction In this study we propose to investigate the effect of the neovascularisation and blood flow to the sternum and surrounding tissues in diabetic & non-diabetic patients by using a laser Doppler imager. The reasons for the delayed healing are not entirely clear, but are thought to include both mechanical factors such as poor wiring of the breastbone during surgery, and biol...

We report a rare case of giant cell tumor (GCT) of the sternum in a 55-year-old man. He presented with a bony mass in the body of the sternum that had been slowly growing over 6 months. The patient was treated by surgical curettage and cementation. Histological study showed typical GCT findings with cytogenetic abnormalities of many telomeric associations of chromosomes, predominantly the 19q arm.

We report the case of a 74-year-old female patient diagnosed with a giant cell tumor of the sternum. The clinical and radiological presentation was indicative of a primary tumor of the sternum. The patient underwent complementary tests and surgery. The pathological examination confirmed the diagnosis. Commonly observed in the long bones of the appendicular skeleton, this type of tumor is charac...

Fig. 1. This 44-year-old male, who had a history of aortic root replacement for acute aortic dissection 9 years ago, suffered impending rupture of dissecting aneurysm in the distal aortic arch. He underwent replacement of the aortic arch and stent graft implantation into the descending aorta. Two weeks later, the sternum was dehisced, but the cut end of the snapped wire was remote from the aort...

tion of the heart, and particularly of the right ventricle, when the heart is in its correct central position. If during intra-uterine life the heart is not central and during development lies to the left side, leaving the mediastinum empty, there will be no positive force to elevate the sternum, but rather a negative pressure which will suck it in. The ribs and sternum ossify early, but the co...

Osteosarcoma (osteogenic sarcoma: OS) is the most common primary malignant bone tumor of long bones, whereas primary osteosarcoma of chest wall, especially in sternum, is extremely rare. We report a 57-year-old man with an immobile slow growing mass located in the middle of the sternum. The patient had no significant pain or tenderness and the past medical history was not remarkable. CT-scan sh...
