Neurofibromatosis (NF) is divided into two types, NF type 1 and NF type 2. Optic nerve gliomas have a high degree of association with NF type 1. NF 2, less commonly seen, is a complex of cutaneous and deep neural tumors. It is an autosomal dominant familial disorder in which CNS is affected in about 15% of the cases. Bilateral acoustic neuromas are pathognomonic of NF type 2 which may be associ...

Orbital hypertelorism is an increased distance between the bony orbits and can be caused by frontonasal malformations, craniofacial clefts, frontoethmoidal encephaloceles, glial tumors or dermoid cysts of the root of the nose, and various syndromic or chromosomal disorders. We report a series of 7 cases of hypertelorism that were treated in our hospital. The underlying causes in our series were...

Bone hemangiomas are extremely rare in the ribs, with only a handful of cases reported in the literature. A case of a rib hemangioma is presented in which the pre-resection diagnosis was an aggressive chest wall tumor. The plain film, CT, MRI and bone scan features of the lesion were reviewed with the pathological correlation. On imaging, the lesion was expansile and lytic, and it also had fine...

Aneurysmal bone cyst is a rare benign tumor of the bone that can be difficult to distinguish from malignant tumors, especially when it presents in an unusual location. Herein, we report a six-year-old girl with a primary aneurysmal bone cyst in an uncommon location. It originated from the 4th rib and she presented with a huge chest wall mass. Despite the large size of the cyst, the only symptom...

When the abdomen in quadriplegic subjects is given a passive mechanical support, the expansion of the lower rib cage during inspiration is greater and the inward displacement of the upper rib cage is smaller. These changes have traditionally been attributed to an increase in the appositional force of the diaphragm, but the mechanisms have not been assessed. In this study, the inspiratory interc...

Isothermal forging is an effective method for forming and manufacturing large-scale titanium alloy components with multi-rib. However, successive filling of the rib-grooves reverse flow material are prone to occur during process, which makes those difficult be filled then resulting in disturbed excessive die loading. The variability billet sizes fluctuation uncertain parameters process have gre...

This study presents the differential diagnosis of metastatic tumors of the pleura vs. primary pleural malignancies in a male patient whose diagnosis was multiple myeloma with pleural involvement and confirmed by bone marrow aspiration and pleural biopsy. Computed tomography (CT) manifestations of this case were retrospectively analyzed, and compared with those of primary pleural malignancies. T...

Rib fractures are a common injury resulting from blunt chest trauma. The most important complications associated with rib fractures include death, pneumonia, and the need for mechanical ventilation. The development of new osteosynthesis materials has stimulated increased interest in the surgical treatment of rib fractures. Surgical stabilisation, however, is not needed for every patient with ri...
