Desmoid-type fibromatosis: imaging features and course
AbstractDesmoid-type fibromatosis (DF) is a soft tissue tumor characterized by infiltrative growth and a tendency toward local recurrence, while it exhibits self-limiting behavior and shows spontaneous regression. With its unpredictable behavior, a change in treatment strategies from initial surgery to nonsurgical management has been proposed, and active surveillance is currently widely chosen as the initial treatment strategy for DF. We reviewed the imaging features of DF regarding its clinical course, focusing on regression cases, postoperative cases, and imaging changes after systemic treatment. (Source: Skeletal Radiology)

Venous thrombosis: a mimic of musculoskeletal injury on MR imaging
AbstractClinical signs and symptoms of venous thrombosis and musculoskeletal pathologies frequently overlap. Sometimes, patients with venous thrombosis undergo MR examinations under an equivocal suspicion of muscle, tendon or articular injury. A low pretest clinical suspicion and lack of familiarity with the conventional MR imaging signs of venous thrombosis may result in failure to diagnose venous thrombosis, delaying treatment and raising morbimortality. In MR imaging, thrombosis presents as venous ectasia with intraluminal heterogeneous content. Small vein thrombosis is often identified as having a branching aspect. Per...

Ewing sarcoma of Hoffa fat pad in the knee: a case report and review of the literature on primary intraarticular sarcomas and Hoffa fat pad masses
We describe a unique case of intraarticular Ewing sarcoma arising in Hoffa fat pad of knee in a woman. The patient was treated successfully with chemotherapy and left knee arthroplasty; however, the tumor recurred after 3 years.We review the literature on primary intraarticular sarcomas and Hoffa fat pad masses in the knee.

Concurrent intraosseous cartilaginous lesions in patients with multiple osteochondromas identified on total-body MR imaging
ConclusionIntraosseous chondroid lesions (enchondroma and ACT) appear to occur more frequently in MO patients than in the general population. TB-MRI allows to detect these, besides the identification of OC with suspicious features. (Source: Skeletal Radiology)

MRI findings of growth plate fractures of the knee: are there age- and fracture-dependent differences?
ConclusionIntraarticular physeal fractures were more common with older children, associate with chondromalacia, and underdo surgical intervention when compared to extraarticular fractures of the knee. While MRI findings of physeal instability were common, no significant differences were found between fractures based on anatomic location or fracture pattern. (Source: Skeletal Radiology)

Relationship between lumbar spinal stenosis and cauda equina movement during the Valsalva maneuver
ConclusionCauda equina movement in cine MRI during the Valsalva maneuver is occasionally observed in patients with severe LSS, and may be associated with pathogenesis of redundant nerve roots. (Source: Skeletal Radiology)

Intravascular papillary hemangioendothelioma disguised as a peripheral sheath tumor of median nerve at the wrist: a case report and literature review
ConclusionCarpal tunnel syndrome, in exceedingly rare occasions, can result from an IVPH. MRI findings may be confused with more common entities. Histopathological confirmation remains necessary for conclusive diagnosis. (Source: Skeletal Radiology)

Intra-labral pigmented villonodular synovitis: a rare case in two adult patients
This article discusses two rare cases of intra-labral pigmented villonodular synovitis (PVNS) of the hip. The hip joint represents the second most common location of pigmented villonodular synovitis, second to the knee [1]. The majority of hip PVNS cases either diffusely involve the synovium or are focal lesions within the joint. The lesions and synovium show foci of low signal intensity related to hemosiderin deposition, a finding that differentiates PVNS from other causes of synovial proliferation. Our case report presents two rare manifestations of PVNS lesions localized within the hip labrum. This presentation could ea...

Detection of bone marrow metastases in children and young adults with solid cancers with diffusion-weighted MRI
ConclusionBone marrow metastases in children and young adults can be equally well detected onb = 50 s/mm2 and 800 s/mm2 images, but ADC values can be misleading. (Source: Skeletal Radiology)

Update of pediatric bone tumors —notochordal tumors, chondrogenic tumors, and vascular tumors of the bone
AbstractThere are numerous bone tumors in the pediatric population, with imaging playing an essential role in diagnosis and management. Our understanding of certain bone tumors has rapidly evolved over the past decade with advancements in next-generation genetic sequencing techniques. This increased level of understanding has altered the nomenclature, management approach, and prognosis of certain lesions. We provide a detailed update of bone tumors that occur in the pediatric population with emphasis on the recently released nomenclature provided in the 5th edition of the World Health Organization Classification of Soft Ti...
