Imaging features of soft-tissue infections.

Skin and soft tissues are among the most common sites of infections. Infections can involve the superficial epidermis to deep muscles and bones. Most infections spread through contiguous structures, although hematogenous spread can occur in the setting of an immunocompromised state and with atypical infections.

Spontaneous pancreatic pseudocyst - superior mesenteric vein fistula: A rare complication of chronic pancreatitis.

Pseudocyst formation is common in chronic pancreatitis. A rare subset of these patients may develop fistulization between the pseudocyst and the portal vein system. We report a case of spontaneous pancreatic pseudocyst - superior mesenteric vein fistula in a 61-year-old male with a history of chronic recurrent calcifying pancreatitis.

Soft-Tissue Infections and Their Imaging Mimics: From Cellulitis to Necrotizing Fasciitis.

Infection of the musculoskeletal system can be associated with high mortality and morbidity if not promptly and accurately diagnosed. These infections are generally diagnosed and managed clinically; however, clinical and laboratory findings sometimes lack sensitivity and specificity, and a definite diagnosis may not be possible. In uncertain situations, imaging is frequently performed to confirm the diagnosis, evaluate the extent of the disease, and aid in treatment planning.

Role of Optimal Quantification of FDG PET Imaging in the Clinical Practice of Radiology.

The combination of fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET) and computed tomography (CT) for dual-modality imaging (PET/CT) plays a key role in the diagnosis and staging of FDG-avid malignancies. FDG uptake by the tumor cells offers an opportunity to detect cancer in organs that appear normal at anatomic imaging and to differentiate viable tumor from posttreatment effects. Quantification of FDG uptake has multiple clinical applications, including cancer diagnosis and staging.

Suture slippage in knotless suture anchors resulting in subacromial-subdeltoid bursitis.

Rotator cuff repair using a suture bridge and knotless suture anchors is a relatively new, but increasingly used technique. The suture bridge technique creates an anatomically similar and more secure rotator cuff repair compared with conventional arthroscopic techniques and the use of knotless anchors eliminates the challenges associated with knot tying during arthroscopic surgery. However, previous in vitro biomechanical tests have shown that the hold of the suture in a knotless suture anchor is far lower than the pullout strength of the anchor from bone.

Vascular access graft and native arterial branch fistulous formation.

This is the first reported case of an unusual complication of upper extremity swelling of the arm in a patient with an arteriovenous (AV) graft for haemodialysis. A graftogram demonstrated an aberrant fistula formation between the native arterial branch and the AV graft (aberrant arterio-graft fistula). Inadvertent back wall laceration of the AV graft during haemodialysis cannulation was postulated to be the aetiology.

Utility of fluorodeoxyglucose-positron emission tomography in the identification of new lesions in lung cancer patients for the assessment of therapy response.

Purpose: Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) has added positron emission tomography (PET) as an optional complement for the detection of new lesions.

Proximal tibial osteophytes and their relationship with the height of the tibial spines of the intercondylar eminence: paleopathological study.

Objective: Tibial spiking (i.e., spurring of tibial spines), eburnation, and osteophytes are considered features of osteoarthritis.

Anterior ankle impingement and talar bony outgrowths: osteophyte or enthesophyte? Paleopathologic and cadaveric study with imaging correlation.

Objective: Bony "spurs" are a major component of anterior ankle impingement syndrome. The two major accepted hypotheses on the origin of these bony spurs are osteophyte formation due to repetitive microtrauma and enthesophyte development because of recurrent capsular or ligamentous traction. The purpose of this study was to provide a detailed evaluation of the bony outgrowths that arise on the anterior aspect of the talus and correlate them with the sites of capsular attachment.
