A 25-year-old patient with osteosarcoma of the right distal femur underwent a bone scintigraphy with Tc-99m methylene diphosphonate (MDP). Whole-body bone scan revealed extensive metastatic disease in the abdominal region. Abdominal computerized tomography confirmed the presence of ascites and calcified masses on the greater omentum and peritoneal surfaces. Here we describe a case of unusual me...

Whole-body magnetic resonance imaging (WB-MRI) is an method without ionising radiation that can provide WB coverage with a core protocol of essential contrasts in less than 40 minutes, and it be complemented sequences to evaluate specific body regions as needed. In many cases, WB-MRI surpasses bone scintigraphy computed tomography detecting characterising lesions, evaluating their response ther...

Lewy body-related disorders are characterized by the presence of Lewy bodies and Lewy neurites, which have abnormal aggregations of α-synuclein in the nigral and extranigral areas, including in the heart. (123)I-metaiodobenzylguanidine (MIBG) scintigraphy is a well-known tool to evaluate cardiac sympathetic denervation in the Lewy body-related disorders. MIBG scintigraphy showed low uptake of M...

osteopoikilosis is a rare benign osteosclerotic bone disorder that may be misdiagnosed as skeletal metastases. here we describe a case of coincidental breast cancer and osteopoikilosis mimicking skeletal metastases. a 41-year-old woman underwent right modified radical mastectomy in april 2007. twenty-eight months after initial treatment, the patient complained of bilateral knee and foot pain. p...

leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. a retrospective review  was performed of the hospital records of 9 children, 6 boys and 3 girls, aged  from 2.5 to 15 years with all initially referred to nemazee hospital nuclear medicine center for whole body bone scanning between 2000 and 2002. bone marrow pathology established all (l1) in two and all (...

Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

Ubiquicidin (UBI) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. We aimed to assess diagnostic value of 99mTc-UBI [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. Nine patients suspected for orthopedic implant infection, all ...
