Enthesitis related arthritis (ERA) is a specific type of juvenile idiopathic arthritis (JIA) and ERA typically begins with enthesitis and peripheral arthritis in the lower extremities, progressing later in the disease to sacroiliitis and spinal involvement. The condition has a strong relationship with the HLA-B27 and primarily affects boys between the ages of 13 and 16 years. We describe an unusual presentation of ERA in a young boy with pubic pain and fever, describing its quintessential magnetic resonance imaging (MRI) findings.

To study the clinical, imaging, and computed tomography (CT)-guided biopsy pathology of patients with infectious sacroiliitis (ISI). We retrospectively analysed 135 patients diagnosed with ISI between 2008 and 2020, comprehensively evaluating clinical characteristics, laboratory test outcomes, pathological examination results, and magnetic resonance images (MRI). Among the 135 patients with ISI, 90 (66.

We wished to compare the diagnostic performance of texture analysis (TA) against that of a visual qualitative assessment in identifying early sacroiliitis (nr-axSpA). A total of 92 participants were retrospectively included at our university hospital institution, comprising 30 controls and 62 patients with axSpA, including 32 with nr-axSpA and 30 with r-axSpA, who underwent MR examination of the sacroiliac joints. MRI at 3T of the lumbar spine and the sacroiliac joint was performed using oblique T1-weighted (W), fluid-sensitive, fat-saturated (Fs) T2WI images.

Department of Radiology, Selcuk University Medical Faculty, Konya, Turkey.
Background: Piriformis syndrome, an often-overlooked cause of sciatica, commonly presents as chronic gluteal pain and poses a diagnostic challenge, particularly in patients with axial spondyloarthritis (axSpA).
Purpose: To examine piriformis muscle abnormalities on sacroiliac magnetic resonance imaging (MRI) and their association with clinical outcomes in patients with axSpA.
Material And Methods: This cross-sectional study included 100 axSpA patients (50 radiographic [r-axSpA], 50 non-radiographic [nr-axSpA]), classified by the 2009 ASAS Axial Spondyloarthritis criteria, who underwent MRI evaluations of the sacroiliac joints over a 6-month period.
Recent Advances in Managing Ankylosing Spondylitis with Andersson Lesion: A Clinical Overview and Case Report.

Introduction: Ankylosing spondylitis (AS) is a chronic inflammatory disorder that primarily affects the spine and sacroiliac joints, leading to pain, stiffness, and progressive thoracolumbar kyphotic deformity. A key complication in advanced AS is the development of Andersson lesions (AL), degenerative vertebral lesions resulting from the disease's progression. These lesions can cause significant mechanical pain, often mistaken for the chronic discomfort associated with AS.
