RESUMO
Vertebral involvement in sarcoidosis is rare and its clinical and imaging features are non-specific. Indeed, because the lesions are hard to differentiate from metastatic disease based on imaging alone, a histological confirmation is advised. Fatty replacement is a well-known finding indicating stabilization and healing in both benign and malignant conditions. It can be used as an indicator of a favorable disease course and response to treatment. We report the case of a 43-year-old woman with multifocal vertebral sarcoidosis lesions and long-term follow-up showing progressive and gradual fatty involution on magnetic resonance imaging (MRI) during 4 years of steroid treatment with a final favorable outcome.

Posttraumatic carpal and carpometacarpal dislocations represent a heterogeneous group of disorders resulting from high-energy wrist trauma. Perilunate injury is the most common and best-known manifestation of carpal dislocation, typically occurring after hyperextension trauma. Other forms are very rare and have different causative mechanisms. Carpometacarpal (CMC) dislocations are also uncommon and may affect isolated or multiple CMC joints. These lesions are prone to wrist instability if not treated promptly. The aim of this article is to provide a systematic radiologic approach to the evaluation of wrist injury and to present two acute cases of rare CMC dislocations.
