Department of Paediatric Dentistry, Glasgow Dental Hospital, Glasgow, UK.

Study models are frequently used in orthodontics and are a key part of both initial assessment and treatment planning. They are an important part of comprehensive orthodontic records; furthermore, study models are an essential diagnostic aid that can be studied in detail without the patient being present. We present a case of a 14-year-old boy with an abnormal palatal swelling detected by his specialist orthodontist after review of study models taken at the initial appointment. Read More

Imaging of Fibrous Dysplasia Protuberans, an Extremely Rare Exophytic Variant of Fibrous Dysplasia.

Diagnostics (Basel) 2021 May 31;11(6). Epub 2021 May 31.

Department of Radiology, Nuclear Medicine Division, Naval Medical Center San Diego, 34800 Bob Wilson Drive, San Diego, CA 92134, USA.

This paper details the case report of a 26-year-old man who presented with a growing right-sided skull mass evaluated with ultrasound, non-contrast CT, contrast-enhanced MRI and Tc-MDP whole body bone scan with SPECT/CT.

Excision of fibrous band and application of tension band plating in focal fibrocartilaginous dysplasia: A case report and literature review.

Acta Orthop Traumatol Turc 2021 Mar;55(2):184-188

Department of Orthopaedics and Traumatology, Hacettepe University, School of Medicine, Ankara, Turkey.

Focal fibrocartilaginous dysplasia (FFCD) is a rare disease that can cause angular deformities of long bones. The common pathologic finding is a thick fibrotic band extending from epiphysis to metaphysis on one side of the bone. The tethering effect of the fibrotic band around the growth plate is thought to be the main etiology for the development and progression of the deformity. Read More

Semin Ultrasound CT MR 2021 Apr 29;42(2):150-163. Epub 2020 Aug 29.

Department of Musculoskeletal Imaging, The University of Texas MD Anderson Cancer Center, Houston, TX.

We will provide an imaging-focused discussion of 3 benign bone tumors that do not fit in the categories of cartilaginous tumors or osteoid tumors. We have chosen giant cell tumor of bone, unicameral bone cyst, and fibrous dysplasia. All 3 of these entities are common enough that one does not have to be a musculoskeletal radiologist in a cancer hospital to encounter them occasionally, but none of them should be seen frequently.

Diagnostic performance of Ga-DOTATOC PET/CT in tumor-induced osteomalacia.

Ann Nucl Med 2021 Mar 13;35(3):397-405. Epub 2021 Feb 13.

Department of Diagnostic Imaging and Nuclear Medicine, Graduate School of Medicine Kyoto University, 54 Shogoinkawahara-cho, Sakyo-ku, Kyoto, 606-8507, Japan.

Objective: Tumor-induced osteomalacia (TIO) is caused by typically small tumors that secrete fibroblast growth factor 23 (FGF23). As tumor resection is the only effective treatment for TIO, it is important to detect the culprit tumor. We aimed to assess the utility of Gallium-DOTA-D-Phe(1)-Tyr(3)-octreotide (Ga-DOTATOC) PET/CT in TIO and the correlation between biochemical parameters and the PET/CT results. Read More

Clinical assessment of cemento-osseous dysplasia based on three-dimensional diagnostic imaging: A case report.

Aust Endod J 2021 Apr 1;47(1):105-112. Epub 2021 Feb 1.

Department of Oral and Maxillofacial Radiology, School of Dentistry, Aichi Gakuin University, Aichi, Japan.

Cemento-osseous dysplasia (COD) is a lesion in which periapical bone is replaced by fibrous tissue, including osseous or cementum-like tissue. In the initial stage of COD, radiolucencies are noted at the root apex on periapical radiography, which can be confused with apical periodontitis. Understanding of correct pathological condition and careful assessment of COD is critical to avoid unnecessary endodontic interventions in healthy teeth. Read More
