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...

  Introduction: Almost all malignant tumors have the potential to eventually produce bone metastasis. The aim of the current study was to report the distribution pattern and imaging characteristics of bone metastases detected by conventional whole body bone scintigraphy in patients with different types of malignancies and to assess their relationship with the complain...

Two cases of osteoid osteoma tumor (OO) are presented and our early experience with intraoperative gamma probing to localize OO during surgery is reported. The concept of radioguided surgery was developed 60 years ago and the gamma detection probe technology for radioguided biopsy and/or resection of bone lesions has been applied since the early 1980s. Bone scintigraphy is very important for in...

BACKGROUND Active spondylolysis is an acquired lesion in the pars interarticularis and is a common cause of low back pain in the young athlete. OBJECTIVES To evaluate whether the one-legged hyperextension test can assist in the clinical detection of active spondylolysis and to determine whether magnetic resonance imaging (MRI) is equivalent to the clinical gold standard of bone scintigraphy a...

Skeletal scintigraphy is, in addition to plain radiography, the most important method for diagnosing inflammatory skeletal disease. It is important for the localisation of inflammation as well as for its highly negative, predictive value. The patients reported in this study were examined by three-phase scintigraphy by which the inflammatory process was detected in soft tissue (hyperaemia) in th...

The present case demonstrates a diffuse intense hepatic and, to a lesser degree, spleen, Tc-99m MDP uptake on a routine bone scintigraphy resembling liver-spleen imaging. A 49-year-old female with a history of anaplastic plasma cell tumor and suffering from bone pain was referred for bone scintigraphy to evaluate possible bone metastases. The bone scintigraphy showed diffuse hepatic and spleen ...

Detection of bone metastases in patients with lung cancer has important clinical significance and therapeutic implications, since it causes relevant changes in the patients’ treatment. This study compared the efficacies of 18F-fludeoxyglucose positron emission tomography (18F-FDG PET)/CT, and 99mTc bone scintigraphy [planar and single photon emission CT (SPECT))for detection of bone metastases ...

We studied bone lesion alterations in three patients with diffuse cutaneous leishmaniasis (DCL) by imaging exams (radiography and scintigraphy) and histopathology. Two patients had bone lesions of distal extremities of hands and feet, and one infiltrating plaques in the skin. The study was conducted at three specialized centers (Presidente Dutra Hospital/Nucleus of Tropical Pathology, UFMA-MA; ...

the features of hypertrophic pulmunary osteoarthropathy (hpoa) on radionuclide bone scintigraphy have been well described in case reports and small series of patients. the aim of this study was to investigate prospectively the prevalence and distribution of hpoa in a large series of patients with carcinoma of the lung. two hundred and eleven patients aged 31-89 years (average age 66 years) male...
