Pelvic MRI findings of juvenile-onset ankylosing spondylitis

Ankylosing spondylitis (AS) is the most common clinical subgroup of sero-negative spondyloarthropathies. Radiographic and clinical signs of bilateral inflammatory involvement of sacroiliac joints are the gold standard for the diagnosis of juvenile AS. Although radiographic evidence of sacroiliitis is included in the definition, it is not mandatory for the diagnosis of juvenile AS. The aim of this study is to describe pelvic enthesitis-osteitis MRI findings accompanying sacroiliitis in a group of juvenile AS. Eleven patients suffering from low back pain underwent MRI of the pelvis and were enrolled in this retrospective study. The mean duration of symptoms was 12 months. The mean age of the 11 cases in our study was 12.18 years (range, 6-19). There were eight boys and three girls. Anteroposterior radiographs of the pelvis were obtained in all patients. Sacroiliac joint involvement was detected in all of the cases by pelvic MRI. Pathologic signal changes were detected in the pubic symphisis (osteitis pubis) in ten cases, trochanteric bursitis in six cases, coxofemoral joint in five cases, crista iliaca in three cases, and ischion pubis in three cases. There was increased T2 signal intensity in eight of the 11 cases (72.7%) relevant with soft tissue edema/inflammation. This high correlation between sacroiliitis and enthesitis suggests that enthesitis could be an important finding in juvenile AS

Sparing Surgery for an Epidermoid Cyst of the Testis: A Case Report and Literature Review

Epidermoid cyst of the testis is relatively rare and accounts for less than 1% of all testicular neoplasms. This condition usually occurs in young men and it is mostly detected by self-examination or routine physical examination. The case of a 27-year-old male with an epidermoid cyst of the testis is discussed. The diagnosis was based on ultrasonography and management was with testicular-sparing surgery. At 2-year follow-up, the patient had had no relapse or metastasis. In epidermoid cysts of the testis, high-frequency ultrasonography is a reliable diagnostic imaging method. Organ-preserving surgery is recommended in the management of these lesions

Wilson's Disease Presented with Severe Low Back and Hip Pain as Initial Symptoms and Subsequent Involuntary Movements: A Case Report

A forty-six-year-old male patient was admitted to the hospital with complaints of severe low back and hip pain as well as involuntary body and limb movements. Physical examination revealed left-sided hemiballismus, limited and painful movements of the low back, hip and sacroiliac joints, and Kayser-Fleischer ring on eye examination. Magnetic resonance imaging (MRI) findings of the cranium and lumbar spine were normal. MRI of the hip and sacroiliac joints demonstrated sacroiliac joint effusion, bone marrow edema in both femoral heads, and bilateral psoas bursitis. Hypometabolism was found in the right basal ganglia on Flourodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Hepatic and neurologic symptoms are the first manifestation of Wilson's disease in 30-40% of patients. Wilson disease is one of well known cause of arthropathy, however this is very rare condition. Wilson's disease should be kept in mind in patients with arthropathy and also hepatic or neurologic symptoms. Turk J Phys Med Rehab 2010;56:141-4

A case of brown tumor mimicking fibrous dysplasia in a patient with chronic renal failure

Renal osteodystrophy is one of the major causes of morbidity in patients receiving long-term dialysis treatment for renal failure and after transplantation. Its clinical implications include high-turnover bone disease, low-turnover bone disease, osteomalacia. osteosclerosis, and osteoporosis. A 13-year-old boy who had been on dialysis treatment for renal failure was admitted with a pathologic supracondylar femur fracture after a minor trauma. Radiological studies showed cystic lesions in the femoral supracondyle, left acetabular roof, and right proximal and distal tibia. Based on radiologic appearances of the lesions and on histopathologic findings of the lesion excised from the right distal tibia, brown tumor and fibrous dysplasia were considered in the differential diagnosis. Initially, serum parathyroid hormone level was slightly increased and calcium level was normal. but during follow-up, serum parathyroid hormone level increased significantly, enabling the diagnosis of brown tumor

Diagnostic value of magnetic resonance imaging and scintigraphy in patients with metastatic breast cancer of the axial skeleton: a comparative study

Purpose The goal of this study was to compare the sensitivity of MRI and scintigraphy for detecting metastatic bone disease involving the axial skeleton. Patients and Methods A total of 59 patients (58 women and 1 man, age range 28-83 years, mean age 53.0 years) with histopathologically proven breast cancer during a 15-month period (between April 2003 and January 2004) were included in the study. All the patients underwent scintigraphy and MRI examinations for staging, follow-up, or evaluation of bone pain. Results MR imaging revealed 59 metastases in 59 patients (sensitivity, 95%; specificity, 100%; positive predictive value, 100%). Four lesions detected by MRI were classified as of uncertain origin (grade 2) and 36 lesions were regarded as definitely benign (grade 1). Scintigraphy revealed 44 metastases in 59 patients (sensitivity, 70%; specificity, 94%; positive predictive value, 95%). A total of 29 lesions were considered as of uncertain origin (grade 2), and 26 lesions were regarded as definitely benign (grade 1). About five lesions were graded as grade 2 in scintigraphy, while MRI graded them as degeneration or benign compression (Grade 1). For 11 lesions the same grade was regarded in both MRI and scintigraphy. Two lesions graded as grade 3, and eleven lesions graded as grade 2 in scintigraphy demonstrated no pathological signal intensity in MRI. In total, 18 lesions with no activity in scintigraphy were graded as grade 3 lesions in MRI. Conclusion MRI is more sensitive than scintigraphy in the detection of bone metastases. MRI appears to be able to screen patients more effectively than scintigraphy if the spine and pelvis are included because metastases merely outside the axial skeleton are rare

Pain & resistance in patients with adhesive capsulitis during contrast material injection phase of MR arthrography

Background & objectives: Adhesive capsulitis of the shoulder is a condition of unknown aetiology that results in the development of restricted active and passive glenohumeral motion. It has been reported that magnetic resonance (MR) imaging is useful in diagnosing adhesive capsulitis. We carried out this study to assess how pain and/or resistance during contrast material injection affects the diagnosis of adhesive capsulitis on magnetic resonance (MR) arthrography
