Artifactual spinal metastases imaged by PET/CT: a case report.
نویسندگان
چکیده
A 55-y-old patient with multiple myeloma presented for restaging after chemotherapy and radiation. The patient had undergone vertebroplasty of multiple thoracic vertebrae because of painful compression fractures. The 18F-FDG PET images showed increased activity at the T8 and T10-T12 vertebral bodies. Comparison of the attenuation-corrected and non-attenuation-corrected images demonstrated that the activity was due to an artifact of attenuation correction. The CT scan correlated the sites of vertebroplasty to the 4 foci of increased uptake of 18F-FDG. The increasing use of vertebroplasty for malignant spinal fractures warrants vigilance for this artifact.

The role of FDG PET/CT in the evaluation of treatment response in a case of calcified ovarian metastases
Evaluation of calcified metastatic lesions by conventional imaging can be challenging. Ovarian cancer metastases can present with calcification which might increase in size and number following therapy. It is not entirely clear whether these calcifications are associated with tumor response or disease progression. Calcified lesions which do not change in size or configuration are particularly p...
متن کاملF-18 FDG PET/CT Imaging of Eccrine Sweat Gland Carcinoma of the Scrotum with Extensive Regional and Distant Metastases
Eccrine carcinoma is an extremely rare malignant skin cancer arising from eccrine sweat glands with a high metastatic potential. It mainly occurs in the elderly, with equal incidence in both sexes. It usually spreads to regional lymph nodes, with liver, lungs, and bones being the most common sites of distant metastasis. Because of tumor rarity, little is known about the value of F18- FDG PET/CT...

Management of locally advanced colon cancer metastases is challenging and operation carries an increased risk of morbidity and mortality. The knowledge of exact sites of involvement can aid the surgeon to make a decision regarding complete resection or palliative therapy. PET/CT scan is an advantage in this setting because metabolic alterations often precede the anatomic changes; moreover, it c...
متن کاملUtility of F-18 FDG PET/CT for Detection of Bone Marrow Metastases in Prostate Cancer Patients Treated with Radium-223
A 76-year-old man with symptomatic bone metastases from castrationresistant prostate cancer underwent Radium-223-dichloride (Ra-223) therapy. Before Ra-223 therapy, he had normal peripheral blood cell counts. Ra-223 therapy relieved his shoulder and low back pain. The elevation of the serum prostate-specific antigen (PSA), doubling every month during Ra-223 therapy, suggested a PSA flare or rel...

FDG PET/CT as a molecular imaging modality detected spinal cord metastases in a patient with medulloblastoma. Increased FDG uptake was reported as negatively correlated with survival in medulloblastoma in the literature. Although, spinal cord metastases associated with medulloblastoma detected with FDG-PET/CT imaging is a rare condition. To the best of our knowledge, this is the first report on...
