"Multimodality imaging of the extrapleural space lesions".

Clin Imaging 2021 Nov 16;79:64-84. Epub 2021 Apr 16.

Department of Radiology, Cardiothoracic Division, University Hospitals Cleveland Medical Center, Cleveland, OH, USA. Electronic address:

Extrapleural space (EPS) is a potential space between the outer layer of the parietal pleura and the inner layer of the chest wall and the diaphragm. Many different pathologies including chronic inflammatory conditions, infections, trauma, neoplastic disease (both benign and malignant) as well as many infiltrative disorders can involve the EPS. It is one of the frequently overlooked entity on imaging due to relative lack of understanding of the anatomy and the imaging appearances of the diseases localized to this space. Read More

Staging and Classification of Primary Musculoskeletal Bone and Soft-Tissue Tumors According to the 2020 WHO Update, From the Special Series on Cancer Staging.

AJR Am J Roentgenol 2021 11 14;217(5):1038-1052. Epub 2021 Apr 14.

Mayo Clinic College of Medicine, Rochester, MN.

Staging of primary musculoskeletal bone and soft-tissue tumors is most commonly performed using the AJCC and the Enneking or Musculoskeletal Tumor Society (MSTS) staging systems. Radiologic imaging is integral in achieving adequate musculoskeletal neoplastic staging by defining lesion extent and identifying regional lymph node involvement and distant metastatic disease. Additional important features in surgical planning, though not distinct components of the staging systems, include cortical involvement, joint invasion, and neurovascular encasement; these features are optimally evaluated by MRI.

Semin Ultrasound CT MR 2021 Apr 29;42(2):194-200. Epub 2020 Aug 29.

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

Imaging evaluation of soft tissue masses is essential for diagnosis, preoperative staging, and post-treatment follow-up. Magnetic resonance imaging plays the major role because of its superior resolution that helps in better tissue characterization, and its multiplanar imaging capability in evaluation of soft tissue masses. Additional imaging techniques, such as radiographs, computed tomography, positron-emission tomography-CT, radionuclide scintigraphy and ultrasonography, also play vital roles by providing additional information required in management of soft tissue masses.

Composite PEEK/carbon fiber rods in the treatment for bone tumors of the cervical spine: a case series.

Eur Spine J 2020 12 20;29(12):3229-3236. Epub 2020 Jul 20.

IRCCS Istituto Ortopedico Rizzoli, Bologna, Italy.

Introduction: Radiotherapy (RT) is frequently applied as an adjuvant therapy during spinal tumors treatment. Metallic implants can interfere with RT planning and execution, as it is known that metallic implants produce a backscattering effect that can limit RT accuracy and their presence can be associated with unwanted dose increase. PEEK/carbon fiber implants are designed to reduce these problems but their application in the cervical spine is limited, due to the reduced number and types of implants, the screw dimensions and the absence of lateral mass screws.

18F-FDG PET/CT in the Staging and Management of Breast Cancer: Value in Disease Outcome and Planning Therapy.

Clin Nucl Med 2017 Mar;42(3):191-192

From the *Unidad PET/TC, CETIR-ERESA, C/J Anselm Clave, Esplugues, Barcelona; and †Servicio Oncología, Hospital Sant Pau i Santa Tecla, Tarragona, Spain.

In hormone receptor-positive locally advanced breast cancer, endocrine therapy becomes an integral part of the therapeutic strategy. There are now significant numbers of available hormonal directed compounds, including selective aromatase and mTOR inhibitors, which allow an important therapeutic advance in these patients. Sequential F-FDG PET/CT studies provided essential information regarding response to different treatments, including targeted therapies, and adverse therapeutic effects that helped to better define the right moment to implement each therapeutic approach.
