Extraosseous accumulation of bone-seeking agents is rare, but has been previously reported in pediatric sarcomas and neuroblastomas. We present an unusual case of a 5-month-old male with an abdominal mass observed clinically by his parents and referring pediatrician. Contrast abdominal computerized tomography confirmed the presence of a large pelvic mass that was diagnosed pathologically as emb...

INTRODUCTION To the best of our knowledge, we present for the first time the bone scintigraphy findings of a patient with Morquio's syndrome. CASE PRESENTATION A 46-year-old Caucasian man with Morquio's syndrome presented with lower back pain six weeks after a left total hip replacement. A whole body bone scan demonstrated an anthropomorphic skeletal pattern consistent with a mucopolysacchari...

UNLABELLED Bone scintigraphy, despite being non-specific, is a very sensitive and simple investigation for patients with active Paget's disease of the bone. Skeletal metastases and Paget's disease may co-exist in the elderly patients as both conditions are commonly seen in this age group. Clinical and radiological correlation may help to improve the diagnostic specificity of a bone scintigram. ...

Skeletal metastases are very common in prostate cancer and represent the main metastatic site in about 80% of prostate cancer patients, with a significant impact in patients' prognosis. Early detection of bone metastases is critical in the management of patients with recently diagnosed high-risk prostate cancer: radical treatment is recommended in case of localized disease; systemic therapy sho...

Malignant melanoma is a malignancy located predominantly in the skin and the incidence of melanoma increases. We compared the markers of bone metabolism - osteocalcin (OC), beta-carboxyterminal cross-linked telopeptide of type I collagen (β-CrossLaps, β-CTx) and tumour marker - human epididymis protein 4 (HE4) in the serum with finding during the entry examination and the check-up of whole-body...

Fibrous dysplasia (FD) is a benign fibroosseous bone disorder. It has poliostotic and monostotic patterns. Monostotic FD is frequently asymptomatic and is usually discovered incidentally by radiologic imaging performed for other reasons. Bone scintigraphy is valuable for identifying disease extent. Craniofacial FD (CFD) is a form of the disease where lesions are limited to contiguous bones of t...

INTRODUCTION Two-stage revision arthroplasty is today considered as the gold standard for control of chronic deep prosthetic infection. Although the revision arthroplasty should only be considered when infection is eliminated, the diagnosis of residual infection prior to the revision remains a challenging problem. MATERIALS AND METHODS We evaluated triple-phase bone scintigraphy as a useful d...

UNLABELLED To assess the cost-effectiveness of various strategies for the diagnostic management of clinically suspected scaphoid fracture, a decision-analytic model was built to evaluate three strategies and to compare them with a (clairvoyant) reference diagnostic management strategy. METHODS Evaluated strategies were: (A) repeated radiography up to 2 wk; (B) repeat radiography up to 6 wk; a...

UNLABELLED Imaging protocols for suspected scaphoid fractures among investigators and hospitals are markedly inconsistent. We performed a systematic review and meta-analysis to assess and compare the diagnostic performance of bone scintigraphy, MRI, and CT for diagnosing suspected scaphoid fractures. Twenty-six studies were included. Sensitivity, specificity, and diagnostic odds ratio were pool...

OBJECTIVE This study aimed to present seven cases of avascular necrosis of the sesamoid and report the role of bone scintigraphy in the diagnosis of these patients. METHODS Seven patients with clinical suspicion of avascular necrosis of the sesamoid underwent three-phase bone scintigraphy with 30 mCi of (99m)Tc-MDP. RESULTS Most of the patients were young female adults with complaints of li...
