This article is a case-based review of the broad spectrum of tumors with musculoskeletal histology that can arise in the abdomen or pelvis and involve the soft tissues, muscle, and bone. In this article, pathology-proven cases are presented with a focus on radiographic, computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography findings. The imaging features that differentiate tumors with musculoskeletal histology from more common abdominal tumors are discussed. Representative cases include malignant fibrous histiocytoma, chondrosarcoma, Ewing sarcoma, hemangiopericytoma, desmoplastic fibroma, neurofibrosarcoma, osteosarcoma, intimal sarcoma, liposarcoma, leiomyosarcoma, synovial sarcoma, teratoma, and chordoma. A variety of tumors with musculoskeletal histology can arise in the abdomen and pelvis. In some cases, unique imaging characteristics allow a confident diagnosis, whereas other cases have a more nonspecific appearance. Recognition of imaging features that suggest a musculoskeletal tumor including direct extension from a bone or neural foramen, the presence of cartilaginous or osseous matrix, or macroscopic fat would allow the radiologist to suggest the proper diagnosis. Recognizing imaging characteristics of tumors with musculoskeletal histology is important clinically as management and prognosis differ from that of more common abdominal tumors.

Metastatic Neuroblastoma Masquerading as Ewing's Sarcoma on X-ray: An Imaging Puzzle in Pediatric Oncology.
J Orthop Case Rep

Department of Pathology, All India Institute of Medical Sciences Bhopal, Bhopal, Madhya Pradesh, India.
Introduction: Neuroblastoma is an embryonic tumor of the peripheral sympathetic nervous system. It is the most common extracranial solid tumor of childhood and accounts for up to 15% of all pediatric cancer fatalities. The manifestation of neuroblastoma is variable depending on the location of the tumor and the presence or absence of paraneoplastic syndromes.

Background: Ewing's sarcoma (EwS), a common pediatric bone cancer, is associated with poor survival due to a lack of therapeutic targets for immunotherapy or targeted therapy. Therefore, more effective treatment options are urgently needed.
Methods: Since novel immunotherapies may address this need, we performed an integrative analysis involving single-cell RNA sequencing, cell function experiments, and humanized models to dissect the immunoregulatory interactions in EwS and identify strategies for optimizing immunotherapeutic efficacy.
Axial spondyloarthritis.
Lancet
January 2025
Rheumazentrum Ruhrgebiet Herne, Ruhr-University Bochum, Germany.
Axial spondyloarthritis manifests as a chronic inflammatory disease primarily affecting the sacroiliac joints and spine. Although chronic back pain and spinal stiffness are typical initial symptoms, peripheral (ie, enthesitis, arthritis, and dactylitis) and extra-musculoskeletal (ie, uveitis, inflammatory bowel disease, and psoriasis) manifestations are also common. Timely and accurate diagnosis is challenging and relies on identifying a clinical pattern with a combination of clinical, laboratory (HLA-B27 positivity), and imaging findings (eg, structural damage on pelvic radiographs and bone marrow oedema on MRI of the sacroiliac joints).

Hospital de la Santa Creu i Sant Pau, Barcelona, Spain.
Background: Denosumab represents a valuable treatment option for unresectable giant cell tumors of the bone (GCTBs). However, no standardized protocols exist determining the length of administration, with few studies having been published on patients who reached the end of treatment.
Aims: To analyze the outcomes of patients diagnosed with GCTB and who had finished single treatment with denosumab.
Association between clinical and MRI-detected imaging findings for people with midfoot pain, a cross-sectional study.
J Foot Ankle Res
March 2025
Leeds Institute of Rheumatic and Musculoskeletal Medicine, University of Leeds, Leeds, UK.
Background: Midfoot pain is common but poorly understood, with radiographs often indicating no anomalies. This study aimed to describe bone, joint and soft tissue changes and to explore associations between MRI-detected abnormalities and clinical symptoms (pain and disability) in a group of adults with midfoot pain, but who were radiographically negative for osteoarthritis.
Methods: Community-based participants with midfoot pain underwent an MRI scan of one foot and scored semi-quantitatively using the Foot OsteoArthritis MRI Score (FOAMRIS).
