Tumefactive fibroinflammatory lesion of the lower extremity: a case report.

We report a case of tumefactive fibroinflammatory lesion located in the anterior, extracapsular part of the right knee, not responding to the conservative treatment. We discuss about the difficulty of the clinical diagnosis of this lesion. In the present case, only the histopathological characteristics confirmed the presence of fibroadipose and inflammatory tissue with lymphocytes and inflammatory cells.

Relationship between alterations of the lumbar spine, visualized with magnetic resonance imaging, and occupational variables.

Although the effect of physical workload on the occurrence of low back pain (LBP) has been extensively investigated, few quantitative studies have examined the morphological changes visualized via magnetic resonance imaging (MRI) in relation to occupational variables. The relationship between the severity of some abnormalities such as lumbar spinal stenosis or spondylolisthesis and physical or psychosocial occupational risk factors has not been investigated previously. In this cross-sectional study patients fulfilled the following inclusion criteria: (1) long-standing (minimum 1-year) LBP radiating down the leg (or not); (2) age more than 40 years; (3) willingness to undergo an MRI of the lumbar spine; and (4) ability to speak Italian.
