Imaging appearance of pre-osseous and osseous phase of fibrodysplasia ossificans progressiva: A rare entity

This is the authors' abstract. We don't add key points for this paper.

Fibrodysplasia ossificans progressiva (FOP) is an infrequent autosomal dominant disorder, characterized by progressive heterotopic ossification of soft tissues including skeletal muscles, tendons, ligaments, fascia, and aponeuroses. Clinically and radiologically, it may be misdiagnosed a soft-tissue neoplasm or inflammatory/infective myositis. The knowledge and awareness of early imaging appearances, soft tissue, and skeletal deformities can lead to early diagnosis before ossification starts to occur, leading to dedicated treatment and prevention of unnecessary biopsies/iatrogenic trauma. We describe a rare case of clinically and radiologically diagnosed fibrodysplasia ossificans progressiva (FDOP) in a 5-year-old girl. This report highlights the radiological findings and the implications of this disorder.
