UNLABELLED Lumbosacral transitional vertebrae can alter the biomechanics of weight transfer at the affected spinal segment. Low-back pain may result. This study assessed what skeletal scintigraphy reveals about stress associated with a lumbosacral transitional vertebra in young patients with low-back pain. METHODS The study population included 48 patients (30 male, 18 female; age range, 6-19 ...

Osteoid osteoma (OO) is a relatively common skeletal neoplasm, frequently involves long bones. OO of rib is extremely rare, including 0.23-2% of OO cases. Most of them arose in posterior arc, frequently in its head or neck and might lead to painful scoliosis. Involvement of anterior aspect of a rib is extremely rare. Skeletal scintigraphy is highly sensitive for detection of OO. “Doubl...

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...

An enostosis or bone island is a benign bony lesion that is almost diagnosed based on clinical and radiologic defining characteristics. One of the known diagnostic procedures in the evaluation of enostosis is bone scintigraphy. Generally, we don’t expect to see increased uptake by enostosis in the bone scan. Herein we present a 52-year-old lady who was suffering from chronic low back pain that ...

The usefulness of bone marrow scintigraphy with 99mTc-HMPAO-labeled leukocytes (leukocyte bone marrow scintigraphy) in the diagnosis of skeletal metastases of cancers was investigated in 70 lesions in 27 patients with various types of cancer. The final diagnosis of skeletal metastases was based on one or more criteria consisting of histological confirmation, typical findings of metastases by bo...

BACKGROUND Endemic nasopharyngeal carcinoma (NPC) commonly metastasizes to the lungs, liver, and bones. This study aims to assess the efficacy of 4 distant metastasis staging modalities, namely (1) conventional work-up comprising chest X-ray, liver ultrasound, and skeletal scintigraphy, (2) CT of the thorax, abdomen, and skeletal scintigraphy, (3) (18)F-fluorodeoxyglucose positron emission tomo...

Skeletal scintigraphy, which has now been established as a useful and accurate method of detecting early skeletal metastases and assessing their response to treatment, has been investigated for its pathological basis. Histological examination of several hyndred necropsy specimens, from sixty-eight patients who died from malignant disease, showed a significant increase of osteoid and immature wo...

Thallium-201 scintigraphy was performed in 8 children with neuroblastoma, and uptake by the tumors was evaluated in comparison with the results of 123I-MIBG scintigraphy. No primary tumors or metastatic lymph nodes showed 201Tl accumulation, but in 4 cases of bone marrow metastases accompanied by focal cortical invasion, the metastatic lesion was demonstrated more clearly on the early image tha...
