Calcifying aponeurotic fibroma is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet in children and adolescents. We report an unusual case of a calcifying aponeurotic fibroma with diffuse intra-articular involvement of the carpal joints in a 59-year-old female. Radiographs and computed tomography scans revealed a large lobulated soft tissue mass with multiple stippled calcifications around the carpal joints and numerous erosions of the second to fifth carpometacarpal and intercarpal joints...

Imaging plays an important role in the diagnosis and therapeutic response evaluation of muscular diseases. However, one important limitation is its incapacity to assess the in vivo biomechanical properties of the muscles. The emerging shear wave sonoelastography technique offers a quantifiable spatial representation of the viscoelastic characteristics of skeletal muscle. Elastography is a non-invasive tool used to analyze the physiologic and biomechanical properties of muscles in healthy and pathologic conditions...

Tuberculous spondylodiscitis usually affects the dorso-lumbar spine, and its cervical location is a rare condition that can mimic other diseases and consequently cause treatment delays. We report a case of tuberculous spondylodiscitis of the lower cervical spine discovered under unusual circumstances in a patient with severe polytrauma involving a cranio-cerebral trauma, a non-displaced fracture of the two laminæ and the spinous process of the C6 vertebrae as well as fibular and tibial shaft fractures. The patient underwent static tibial nailing, and a collar with occipital and chin supports was applied...

Atypical lipomatous tumor/well-differentiated liposarcoma is the most common sarcoma of soft tissue in adults. We describe the clinical, radiologic, and pathologic features of an atypical lipomatous tumor arising within the soft tissue of the left hand of a 68-year-old female that underwent transformation to dedifferentiated liposarcoma and eventually metastasized. At initial presentation, imaging demonstrated an extensively calcified fatty soft tissue mass with displacement of the digits. Following biopsy and staged debulking, the patient subsequently developed local recurrence, dedifferentiation, and widespread metastases to the lungs, pancreas, bone, and soft tissues...

In this report, we present the case of an intra-articular synovial lipoma in a 58-year-old female with a coincident marked unilateral hip osteoarthritis. This patient suffered from right hip pain that developed gradually over 2 years. Physical examination noted decreased range of motion and evidence of impingement. MR and CT images showed an intra-articular fat-intense mass in the hip joint that was excised and confirmed as a synovial lipoma on histology. This case reveals that an intra-articular lipoma of the hip could be accompanied by pain or impingement and followed by hip osteoarthritis even in the absence of trauma...

OBJECTIVE: The purpose of this study was to develop quantitative T2 mapping methodology in asymptomatic shoulders for the entire mappable region of the glenohumeral cartilage in the coronal and sagittal planes, to assess the feasibility and limitations of the development of a diagnostic tool for future application in symptomatic patients. MATERIALS AND METHODS: Twenty-one asymptomatic volunteers underwent sagittal and coronal glenohumeral T2 mapping, as the spherical geometry of the humeral head obviates the need to evaluate the entire glenohumeral cartilage in a single plane...

A 32-year-old male presented with a right thumb lesion of 11-month duration. A clinical diagnosis of pyogenic granuloma was entertained but the lesion failed to respond to conservative therapy and eventually necessitated amputation of his thumb. MRI of the right thumb showed an ill-defined, heterogeneously enhancing, infiltrating mass within the dorsal soft tissues abutting the distal phalanx and measuring 4.2 × 2.4 × 0.7 cm. Histologically, the tumor was composed of a high-grade osteosarcoma with a chondrosarcomatous component localized within the underlying bone and a more superficial spindle cell component in the overlying soft tissue...

OBJECTIVE: Although many types of ankle fracture can be combined with syndesmosis injury, preoperative imaging studies rarely reveal instability of the syndesmosis. This study assessed the use of magnetic resonance imaging (MRI) for syndesmotic instability in patients with unstable ankle fracture. METHODS: A total of 74 patients who were treated for Lauge-Hansen supination external rotation/Weber B type fracture or pronation external rotation/Weber C type fracture and who underwent MRI for preoperative assessment were enrolled...

OBJECTIVE: To determine if intra-articular signal changes at the sacroiliac joint space on MRI have added diagnostic value for spondyloarthritis, when compared to bone marrow edema (BME). MATERIALS AND METHODS: A retrospective study was performed on the MRIs of sacroiliac joints of 363 patients, aged 16-45 years, clinically suspected of sacroiliitis. BME of the sacroiliac joints was correlated to intra-articular sacroiliac joint MR signal changes: high T1 signal, fluid signal, ankylosis and vacuum phenomenon (VP)...
