Entheses are sites where tendons, ligaments, joint capsules or fascia attach to bone. Inflammation of the entheses (enthesitis) is a well-known hallmark of spondyloarthritis (SpA). As entheses are associated with adjacent, functionally related structures, the concepts of an enthesis organ and functional entheses have been proposed. This is important in interpreting imaging findings in entheseal...

Bone metastases from carcinomata are a medical and social issue. About one-half of all primary cancers tend to disseminate to the skeleton, which is the third most frequent site of metastatic spread after the lung and the liver. Epidemiological investigation has shown that of 1.2 million new cases of cancer each year in the USA, about 300 000 will eventually develop a bone metastasis. Tumours w...

Osseous sequestration has been recognized with increased frequency in South American camelids. In horses and cattle, sequestration is most commonly associated with traumatic events that lead to localized cortical ischemia and bacterial invasion secondary to loss of adjacent periosteal and soft tissue integrity and viability. In humans, osteomyelitis without prior trauma is rarely seen in adults...

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...

Boxfishes (superfamily Ostracioidea, order Tetraodontiformes) are comprised of 37 species within the families Aracanidae (13 sp.) and Ostracidae (24 sp.). These species are characterized by several dramatic reductive trends in their axial and appendicular skeleton, and by the presence of a carapace formed by enlarged and thickened scale plates. While strong support exists for the monophyly of b...

BACKGROUND Prophoca and Leptophoca represent the oldest known genera of phocine seals, dating from the latest early to middle Miocene. Originally, Prophoca rousseaui and Prophoca proxima were described based on fragmentary remains from the Miocene of Belgium. However, several researchers contested the union of Prophoca rousseaui and Prophoca proxima into one genus, without providing evidence. T...

Objective - The aims of this study were to determine the approximate radiographic closure time of the growth plates of the fore and hind limbs of Marghoz goat as a small breed of goat is distributed over the western and North-West of Iran near to the Turkey and Iraqi borders and to compare these closure times with those previously published.Design- Experimental studyAnimals- 20 heal...
