Osteoid osteoma: multimodality imaging with focus on hybrid imaging.

Eur J Nucl Med Mol Imaging 2018 Oct 19. Epub 2018 Oct 19.

Department of Radiology and Nuclear Medicine, Cantonal Hospital Lucerne, Lucerne, Switzerland.

Osteoid osteoma is a painful, benign, osteoblastic lesion that occurs in younger patients and affects the extremities or the axial skeleton. While plain film findings may suggest the diagnosis, in complex anatomical regions such as the spine, pelvis, wrist and foot advanced imaging modalities are often required. A typical nidus surrounded by sclerosis or cortical thickening characterizes osteoid osteoma on plain radiography and CT. Read More

Self Limiting Sternal Tumors of Childhood: Two Case Reports.

Authors:
D Adri T Kreindel

Radiologia 2018 Sep 28. Epub 2018 Sep 28.

Servicio de Diagnóstico por Imágenes, Hospital Italiano de Buenos Aires, Ciudad Autónoma de Buenos Aires, Argentina.

Sternal tumours are rare in children. The differential diagnoses include a wide spectrum of benign (from bone cyst to osteoblastoma, osteochondroma and fibrous displasia) and malignant tumours (Ewing's sarcoma, chondrosarcoma rhabdomyosarcoma), inflammatory lesions and infectious processes. The SELSTOC (Self Limiting Sternal Tumours of Childhood) are entities of non-specific origin, they are self-limiting and characterised by a rapidly growing tumour that disappears spontaneously with no history of trauma or active infection.

Periostin expression in neoplastic and non-neoplastic diseases of bone and joint.

Clin Sarcoma Res 2018 5;8:18. Epub 2018 Sep 5.

1Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal and Sciences, Nuffield Orthopaedic Centre, University of Oxford, Oxford, OX3 7HE UK.

Background: Periostin is a matricellular protein that is expressed in bone and joint tissues. To determine the expression of periostin in primary bone tumours and to assess whether it plays a role in tumour progression, we carried out immunohistochemistry and ELISA for periostin in a range of neoplastic and non-neoplastic bone and joint lesions.

Methods: 140 formalin-fixed paraffin-embedded sections of bone tumours and tumour-like lesions were stained by an indirect immunoperoxidase technique with a polyclonal anti-periostin antibody. Read More

Cytological diagnosis of osteoblastoma of the talus: Case report with unusual presentation and diagnostic pitfalls.

Cytojournal 2018 27;15:20. Epub 2018 Aug 27.

Department of Orthopaedics, Himalayan Institute of Medical Sciences, Dehradun, Uttarakhand, India.

Osteoblastoma is a rare bone tumor mostly affecting the young adults and commonly involving the spinal cord and long bones. Talus is the uncommon site of presentation, and if involved, then the neck is more commonly involved than the body of talus. The cytological diagnosis of osteoblastoma is limited, and to the best of our knowledge, its fine-needle aspiration (FNA) in the talus has still not been reported in the literature. Read More

Department of Oral Pathology, Government Dental College and Hospital, St. George Hospital Campus, Near Chhatrapati Shivaji Terminus Area, Fort, Mumbai, Maharashtra 400001, India.

Radiolucent lesions of Temporomandibular Joint (TMJ) represent a diagnostic challenge and a treatment conundrum. Biopsy of the lesions is technically difficult owing to their complex anatomy. The Differential Diagnosis (DD) includes a wide array of lesions including Simple Bone Cyst, Ameloblastoma, Central Giant Cell Granuloma, Hemangioma, Osteoblastoma, Osteochondroma, Chondroblastoma, Chondrosarcoma, Neurofibroma and metastatic malignant lesions though none has a specific predilection for TMJ.

We reported the case of a 22 year-old boy who suffered a periosteal osteoblastoma of the distal fibula. The radiographic features of our case did not correlate with the majority of periosteal osteoblastomas of the long bones reported in the literature and were identical to a periosteal aneurysmal bone cyst. Periosteal osteoblastoma is a very rare tumor with a wide range of clinical and radiological features, showing in 15% of cases association with secondary aneurysmal bone cyst. Read More

Recurrent rearrangements of FOS and FOSB define osteoblastoma.

Nat Commun 2018 06 1;9(1):2150. Epub 2018 Jun 1.

Wellcome Trust Sanger Institute, Hinxton, Cambridgeshire, CB10 1SA, UK.

The transcription factor FOS has long been implicated in the pathogenesis of bone tumours, following the discovery that the viral homologue, v-fos, caused osteosarcoma in laboratory mice. However, mutations of FOS have not been found in human bone-forming tumours. Here, we report recurrent rearrangement of FOS and its paralogue, FOSB, in the most common benign tumours of bone, osteoblastoma and osteoid osteoma. Read More

Osteoblastomatosis (OBLT), also referred to as multifocal osteoblastoma (OB), is an unusual and recently described entity consisting of multifocal tumors histologically consistent with osteoblastoma and osteoid osteoma (OO) but radiologically mimicking a vascular bone lesion. OBLT treatment is based on aggressive procedures, such as amputation, en bloc resection, and chemotherapy. Only one previously reported case was successfully treated following a multimodal approach consisting of curettage, cryotherapy, intravenous bisphosphonates, and radiofrequency ablation. Read More

Department of Oral Pathology, Government Dental College and Hospital, Aurangabad, Maharashtra, India.

Introduction: Osteosarcoma is a malignant mesenchymal tumor whose cancerous cells produce osteoid matrix. It is a common primary malignant bone tumor, representing 23% of total head and neck malignancies. Osteosarcomas of the jaws are rare lesions, representing only 4-7% of all osteosarcomas. Read More

CT-guided radiofrequency ablation of spinal osteoblastoma: treatment and long-term follow-up.

Objective: Osteoblastoma (OB) is a painful, rare, benign bone tumour usually observed in young populations, and this condition involves the spine in up to one-third of cases. We sought to focus on the minimally invasive treatment of spinal OB with radiofrequency ablation (RFA) under computed tomography (CT) guidance. When performed near the spinal cord, surgery can lead to instability of the spine, sometimes requiring additional interventions to stabilise the segments involved, and can cause the precocious onset of arthrosis or other degenerative diseases.

Benign Bone Conditions That May Be FDG-avid and Mimic Malignancy.

Semin Nucl Med 2017 07 12;47(4):322-351. Epub 2017 Apr 12.

Department of Radiology and Nuclear Medicine, Deventer Ziekenhuis, Deventer, The Netherlands.

Positron emission tomography with the radiotracer F-fluoro-2-deoxy-d-glucose (FDG) plays an important role in the evaluation of bone pathology. However, FDG is not a cancer-specific agent, and knowledge of the differential diagnosis of benign FDG-avid bone alterations that may resemble malignancy is important for correct patient management, including the avoidance of unnecessary additional invasive tests such as bone biopsy. This review summarizes and illustrates the spectrum of benign bone conditions that may be FDG-avid and mimic malignancy, including osteomyelitis, bone lesions due to benign systemic diseases (Brown tumor, Erdheim-Chester disease, Gaucher disease, gout and other types of arthritis, Langerhans cell histiocytosis, and sarcoidosis), benign primary bone lesions (bone cysts, chondroblastoma, chondromyxoid fibroma, desmoplastic fibroma, enchondroma, giant cell tumor and granuloma, hemangioma, nonossifying fibroma, and osteoid osteoma and osteoblastoma), and a group of miscellaneous benign bone conditions (post bone marrow biopsy or harvest status, bone marrow hyperplasia, fibrous dysplasia, fractures, osteonecrosis, Paget disease of bone, particle disease, and Schmorl nodes).
