The purpose of this educational exhibit is to illustrate the radiological appearance of various ossified soft tissue lesions. The differential diagnosis is wide, with entities ranging from benign to malignant. Using instructive and interesting cases encountered at our department, this presentation will outline an approach to forming a differential diagnosis. Various teaching points will be highlighted. Pathological correlation will be included where available. The cases to be presented include: Myositis ossificans Fibrodysplasia ossificans progressiva Tenosynovial osteochondromatosis Dysplasia Epiphysealis Hemimelica Pseudohypoparathyroidism - Albright’s hereditary osteodystrophy Phlebolith in a vascular malformation Pilomatrixoma Heterotopic ossification Synovial Sarcoma This presentation will highlight the distinguishing imaging characteristics of each entity and help narrow the differential diagnosis for a radiologist when faced with a pediatric ossified soft tissue lesion.

<b>Purpose: </b>¹⁸F-FDG Positron Emission Tomography (PET-CT) has been shown to be superior to other imaging modalities in assessment of soft tissue involvement with Langerhans Cell Histiocytosis (LCH) and is now commonly included in the staging workup of LCH. Our purpose is to analyze the utility of skeletal survey in addition to PET-CT scan for detecting bone lesions in children with LCH and to evaluate if skeletal survey can be eliminated from the staging workup of LCH in order to reduce radiation exposure.
