RESUMO
BACKGROUND: Inflammatory changes of the foot are comparatively rare and can be a challenge for radiologists with respect to the differential diagnosis, especially in cases with pre-existing degenerative changes of the foot skeleton. Comprehensive anamnesis and the use of contrast-enhanced MRI diagnostics are therefore often essential for diagnosis. OBJECTIVES: This review provides a cursory overview of the morphological characteristics of inflammatory changes of the foot and their differential diagnoses with a focus on osteomyelitis, joint infections, rheumatological diseases and tenosynovitis.

An osteoid osteoma is a benign bone-forming tumor which usually presents in childhood and adolescence and is characterized by extensive nocturnal pain. Computed tomography (CT) is used to reveal the typical radiolucent nidus surrounded by a sclerotic reaction and in magnetic resonance imaging (MRI) a nidal enhancement and perifocal edema can confirm the diagnosis. Having shown excellent success rates radiofrequency ablation has become the treatment of choice which allows minimally invasive and precise destruction of nidal tumor tissue. By using thermal protection techniques and multiple ablation positions successful therapy of perineural tumors and niduses with diameters of more than 2 cm are possible.
