Imaging of Non-ossifying Fibromas: A Case Series.

Cureus 2021 Mar 25;13(3):e14102. Epub 2021 Mar 25.

Trauma and Orthopaedics, Addenbrooke's Hospital, Cambridge University Hospitals National Health Service Foundation Trust, Cambridge, GBR.

Non-ossifying fibromas (NOFs) are common lesions most frequently found in the growing bones of children and adolescents. Although NOFs are benign, their presence as incidental findings often triggers further investigation as they are sometimes mistaken for more sinister bone lesions such as aneurysmal bone cysts. NOFs can also pose an increased risk of pathological fractures. Read More

"Radiographic demonstration of association of ubernaculum Dentis (Gubernaculum tract) in odontogenic cysts and tumors"-A CBCT finding.

Indian J Radiol Imaging 2020 Jul-Sep;30(3):340-343. Epub 2020 Oct 15.

Department of Oral Pathology and Microbiology, Subharti Dental College, Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, India.

Spectrum of lesions that occur in the jaws have a cyst-like radiographic appearance. These lesions may be odontogenic or non-odontogenic and are often difficult to differentiate them on the basis of their clinical, radiographic features alone. Among odontogenic lesions without mineralization, ameloblastomas, odontogenic keratocysts, and dentigerous cysts can all appear as well-defined, unilocular, well-corticated, lucent lesions that can mimic with non-odontogenic cysts and tumors like nasopalatine duct cyst, aneurysmal bone cyst, central giant cell granuloma, hemangioma and so on.

FUS-NFATC2 or EWSR1-NFATC2 Fusions Are Present in a Large Proportion of Simple Bone Cysts.

Am J Surg Pathol 2020 12;44(12):1623-1634

Faculty of Medicine, University of Ljubljana.

A simple bone cyst (SBC) is a benign bone lesion of unknown etiology. It can be differentiated from an aneurysmal bone cyst (ABC) by radiologic and histopathologic features, as well as by the absence of fusions of the USP6 gene characteristic of an ABC. In an attempt to differentiate between ABC and SBC in a recurrent bone cyst, we performed targeted RNA sequencing and found an EWSR1-NFATC2 fusion and no fusion of the USP6 gene. Read More

Fluid-fluid Levels in Musculoskeletal Tumor Imaging.

Curr Med Imaging 2021 ;17(2):157-165

First Department of Orthopaedics, National and Kapodistrian University of Athens, School of Medicine, Athens, Greece.

Fluid-fluid levels result from the separation of two fluids of differing densities within a cavernous space with the boundary between the two layers running in a horizontal plane at 90 degrees to the direction of gravity. Magnetic resonance imaging is the most sensitive imaging modality to identify fluid-fluid levels. Although the most common bone lesions containing fluid-fluid levels are aneurysmal bone cyst and telangiectatic osteosarcoma, fluid-fluid levels can be observed in a wide variety of bone and soft tissue lesions.

Benign infiltrative myofibroblastic neoplasms of childhood with USP6 gene rearrangement.

Histopathology 2020 Nov 12;77(5):760-768. Epub 2020 Sep 12.

Department of Pathology and Laboratory Medicine, University of Tennessee Health Science Center, Memphis, TN, USA.

Bone Tumors: Benign Bone Tumors.

Yee Lam

FP Essent 2020 Jun;493:11-21

UNC Department of Family Medicine, 590 Manning Drive, Chapel Hill, NC 27599.

Primary benign bone tumors are uncommon and most often affect children and young adults. They typically are detected incidentally on imaging, though some patients present with pain, swelling, or other symptoms. The four main categories of benign bone tumor are: bone-forming (eg, osteoid osteoma, osteoblastoma, fibrous dysplasia, enostosis), cartilage-forming (eg, osteochondroma, enchondroma), connective tissue, and vascular; the latter two are rare.
