Sacroiliitis as a mask of neoplasms in childhood: analysis of a clinical case series

The paper presents a clinical case series that includes 12 children with pelvic bone neoplasms mimicking sacroiliitis, which led to the initial misdiagnosis of enthesitis-related arthritis. It discusses the features of the clinical manifestations and radiation imaging of the tumors and characterizes osteoid osteoma and Hodgkin’s lymphoma, which are located in the sacroiliac joints.
