‘]jlhe number of reports of pathologic processes involving the left pulmonary ligament (the triangular ligament) are few.’3 When present, such processes are frequently mistaken on chest x-ray films for other abnormal conditions. The pulmonary ligament produces no discernible shadow on either the posteroanterior or left lateral projection on a normal chest x-ray film. The radiographic significan...

Ameloblastoma is a benign but locally aggressive epithelial odontogenic neoplasm. It represents 1% of all tumours of the jaw bone. In 80% of cases, it is localized in the mandibular molar and ascending ramus area, mostly associated with an unerupted tooth. It occurs over a wide range of ages (mean age is in the 20s or 30s) and with equal frequency in men and women. Ameloblastoma may be discover...

Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinico-radiological and histological types. Apart from the most commonly encountered clinicopathologic models there are few variants, whose biological profile is unknown or not elicited. The reason for lack of understanding is the scarcity of case report published in th...

PURPOSE To evaluate the interference of radiographic factors in the appearance of sensory deficit related to inferior alveolar nerve (IAN) after third molars (3Ms) removal. METHODS A prospective, double-blind, observational, unicentric study was performed with 126 patients submitted to a surgical procedure of lower 3Ms removal in the period from March to October/2011. Collected data included ...

liquid at room temperature. It tends to form perfectly shaped minute spheres when in contact with air or water because of its high surface tension. Due to such a physical property, the injection of mercury into soft tissue produces a characteristic radiographic appearance. We report a case of mercury foreign bodies within the soft tissue of the arm with imaging findings, including MRI findings.

A 71 year old woman suffering from ankylosing spondylitis with aggressive peripheral joint disease for 46 years developed unusual radiographic features in the hips and knees. The pathogenic processes responsible are uncertain, and no histology is yet available. Although she had been treated with radiotherapy to the knees, there was no similar history to explain the hitherto unreported appearanc...

Ochronotic spondylarthropathy, a long-term musculoskeletal manifestation of alkaptonuria and involvement of joints may lead to a radiographic appearance similar to that of degenerative joint disease. We report the cases of two siblings with progressive familial ochronotic arthropaty treated with total hip arthroplasty.
