UNLABELLED Our objective was to evaluate the accuracy of PET/CT for the diagnosis of Richter's transformation of chronic lymphocytic leukemia (CLL) to diffuse large cell lymphoma. METHODS A retrospective study was performed of 37 patients with CLL who underwent 18F-FDG PET/CT at our institution between March 2003 and July 2005. All PET/CT scans were reviewed in consensus by 2 diagnostic radio...

A 57 years old man was diagnosed by histology of left axillary node as having diffuse large B cell lymphoma. Laboratory investigations revealed hypercalcemia with serum calcium level of 2.9mol/L (normal range: 2.08-2.60). Other blood examinations including complete blood count, coagulation markers, serum parathyroid hormone (PTH), liver and renal function and electrolytes other than calcium wer...

thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. multiple sites of thallium uptake correlated with the findings on serial bone scans and radiographs. bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.

Here we define two cases with a diffuse soft tissue uptake of I-131 in neck and mediastinum on post ablation scan. A diffuse uptake of I-131 in the soft tissue is very rare. In this case report we review the literature and discuss the mechanism of the uptake.

OBJECTIVES Painful disorders of the patellofemoral joint are one of the most frequent complaints in orthopaedic and sports medicine. The aims of this study were to determine whether bone scintigrams of patients suffering from patellofemoral pain syndrome (PFPS) show diffuse uptake and in what bony compartment of the knee uptake, if any, was localised. METHODS Fifty eight patients with chronic...

We present the case of a 60-year-old man with metastatic neuroendocrine tumor of the ileum following ileal resection, being evaluated for 177Lu-based peptide receptor radionuclide therapy. 68Ga-DOTANOC PET/CT showed focal increased tracer uptake in the scrotal region without any morphologic changes on the corresponding CT images. Similar increased tracer uptake was seen on...

INTRODUCTION Prostate cancer is known to have a tendency to metastasize to bone. Skeletal scintigraphy can be used to show multiple lesions. Diffuse metastasis, which is not infrequent in prostate cancer, can also be suspected on the basis of a 'super scan'. However, this phenomenon in nuclear medicine has several other causes that need to be considered. CASE PRESENTATION A patient with a his...
