Plastination is an excellent tool for studying different anatomical and clinical questions. This technique is unique because it offers the possibility to produce transparent slices series that can be easily processed morphometrically. It is very difficult to recognize the subtle widening of the tibiofibular syndesmosis in less severe injuries of ...

The general presentation of osseous and soft-tissue neoplasms of the foot and ankle is not different from lesions encountered in other parts of the body and imaging features may be nonspecific. Some lesions, however, have a predilection for the foot and ankle and may have typical imaging features, such as ...

Mucolipidosis III (ML-III), or pseudo-Hurler polydystrophy, is an autosomal recessive Hurler-like disorder without mucopolysacchariduria. The diagnosis is challenging for rheumatologists since the musculoskeletal presentation is similar to some rheumatic diseases. We report a case of ML-III in a 16-year-old Taiwanese boy. The characteristic findings of sonography and magnetic resonance imaging ...

Involvement of the musculoskeletal system is common if not universal in the clinical course of systemic lupus erythematosus (SLE). Joint involvement on the whole does not cause major erosive disease, however, recent developments in musculoskeletal imaging show clearly the presence of significant bony and soft tissue involvement. It might well ...
