Reliability and accuracy in radiographic measurements of musculoskeletal tumors.

Tumor size and growth are important parameters when evaluating bone and soft tissue neoplasms. There are no reports comparing the intra- and interobserver reliability among physicians in their evaluation of musculoskeletal (MSK) tumor imaging. This study investigates the accuracy and precision of measurements made by orthopedic and radiology physicians in different stages of training.

Intrapancreatic Accessory Spleen Diagnosed As Neuroendocrine Tumor: The Dangers of False Positives and Their Implications in Subsequent Management.

This case serves as a reminder to consider ectopic splenic tissue in the differential diagnosis of pancreatic masses. The literature shows a lack of awareness and overtreatment of this condition due to clinical and radiologic concern for malignancy, namely neuroendocrine tumors (NETs) identified on positron emission tomography (PET)-CT NETSPOT. Given the vast difference in management and prognosis of ectopic splenic anomalies and malignant neoplasms involving the pancreas, accurate diagnosis is imperative to avoid unnecessary invasive procedures such as Whipple or distal pancreatectomy and splenectomy, which are associated with increased morbidity and mortality.

Association of Chondrocalcinosis in Knee Joints With Pain and Synovitis: Data From the Osteoarthritis Initiative.

Objective: To evaluate the relationship between chondrocalcinosis and pain or synovitis in knee joints by examining data from the Osteoarthritis Initiative (OAI).

Methods: Data were obtained from the OAI public-use data sets. The relationship between chondrocalcinosis on baseline knee radiograph and pain at baseline and at 4 years was examined.

Adult intramedullary ewing sarcoma of the proximal hip.

Ewing sarcoma of bone is classically a permeative lesion in the diaphysis of long bones in children. While they occur primarily in children and adolescents, they can be seen in young adults in their 20s, but these are typically seen in flat bones. The permeative nature of the lesion can elicit new bone formation creating a partially sclerotic appearance, cortical expansion presenting as a "Codman triangle," or have an "onion-skin" type of aggressive periosteal reaction/periostitis.
