[Factitious disorder revealed by polymicrobial septic arthritis of a lumbar facet joint diagnosed by percutaneous biopsy].

Septic arthritis of a lumbar facet joint is rare with few reports in the literature. Clinically, septic arthritis of a lumbar facet joint can mimic spondylodiscitis. Imaging is usually required for diagnosis.

Exogenous lipoid pneumonia with unusual CT pattern and FDG positron emission tomography scan findings.

We report a case of an exogenous lipoid pneumonia that appeared as a spiculated calcified mass on CT scan in which a positron emission tomography (PET) scan was performed before histological analysis. The F-18 fluoro-deoxy-D-glucose (FDG) PET showed a pattern highly suggestive of malignancy which, to our knowledge, has not yet been described. Similar to inflammatory and infectious lung diseases, lipoid pneumonia may be a false-positive case of F-18 FDG uptake.

[Imaging of osteoarticular tuberculosis].

Purpose: and methods. To perform an illustrated and educational review of musculoskeletal tuberculosis.

Results: As the incidence of musculoskeletal tuberculosis still increases, a review appears justified.
