: In patients presenting with acute renal failure and known/suspected lymphoma, the diagnosis of diffuse renal involvement is important, as there is potential for rapid resolution with chemotherapy. Although FDG is excreted through the kidneys and focal renal disease may be difficult to identify, diffuse renal FDG is more easily recognized and is always abnormal. We report a patient presenting with acute renal failure and suspected lymphoma. F-18 FDG PET/CT study demonstrated diffuse increased FDG uptake in bilaterally enlarged kidneys. Following 1 cycle of chemotherapy, the renal function normalized. An interim F-18 FDG PET/CT demonstrated normal size and FDG uptake within both kidneys.

In the present communication, an unusual combination of scalp soft tissue and underlying brain involvement with intact skull bone coupled with bilateral renal involvement from a mediastinal diffuse large B cell lymphoma (DLBL) is presented. A 45-year-old man, a diagnosed case of mediastinal DLBL with bilateral lung involvement, was treated with conventional 6 cycles of chemotherapy and local external radiotherapy with initial good treatment response evidenced by considerable regression in mass s...

Abstract:Renal impairment secondary to lymphomatous parenchymal infiltration is uncommon. Early recognition of this cause of acute renal failure (ARF) is important as initiation of steroid therapy often results in rapid improvement in renal function. We highlight the usefulness of the functional asp

Abstract An 82-year-old female patient with hypothyroidism and Hashimoto's thyroiditis noted three years ago to have a small asymmetric goiter (left > right). Nevertheless, a rapid growth of the thyroid over 3-6 months caused dysphagia and shortness of breath. Ultrasound and a thyroid gammagram showed an image consistent with multinodular goiter with a hyperfunctioning nodule in the right lobe. Due to the history of Hashimoto's thyroiditis and a rapid increase in size of the thyroid gland, diagn...

Objective The kidney is a frequent site of involvement in lymphoproliferative disorders. The aim of this study was to demonstrate the prevalence and spectrum of morphologic appearances of renal involvement in patients with lymphoma on helical computed tomographic (CT) scan.

Abstract Diffuse large B cell lymphoma (DLBCL) is the largest subtype of non-Hodgkin's lymphomas (NHLs) and is characterized by relatively frequent extranodal presentation. In these cases, the most common extranodal localizations are stomach, CNS, bone, testis and liver. Simultaneous detection of multiple extranodal involvement at presentation is quite uncommon, with the majority of these cases characterized by gastric or intestinal disease localization. Retrospective analysis concerning multifo...

Summary Differences in genetic origin between nodal and extranodal diffuse large B-cell lymphomas (DLBCL) exist. Using population-based data from the registry of the Danish Lymphoma Group, the present study is the first to analyse clinical implications of nodal versus extranodal presentation of DLBCL. Of 4786 newly diagnosed non-Hodgkin's lymphoma patients in a 16-year period, 1575 (33%) had DLBCL. The annual incidence rate was 2·9 per 100 000; 40% were extranodal. The clinical profile of patien...

Renal lymphoma is most often seen in conjunction with multisystemic, disseminated lymphoma or as tumor recurrence. Renal lymphoma may also be seen in immunocompromised patients or, rarely, as primary disease. Computed tomography (CT) is the most sensitive, efficient, and comprehensive examination for evaluation of the kidneys in patients with suspected renal lymphoma. Helical CT in particular improves detection and characterization of lymphomatous renal involvement by optimizing contrast dynamic...

IN 1878 Sutton and Turner [1] presented to the Pathological Society of London their autopsy findings in nine patients with "Hodgkin's disease and allied conditions." Seven showed visceral involvement by the primary process . In five the kidneys were affected. Two of the latter patients, one a boy whose kidneys weighed 19 .5 and 19 ounces, respectively, had not shown any increase in the number of "colorless corpuscles" in the blood during life and were stated to be suffering from Hodgkin's diseas...

Abstract Renal involvement in Hodgkin lymphoma (HL) is rare, although extralymphatic disease is usually found. Acute kidney injury is a recognized presentation of non-Hodgkin lymphoma, with bilateral kidney involvement, promptly requiring specific treatment. Regarding to HL, this manifestation is extremely rare and lacks pathologic description and management experiences. Herein, we describe a case of HL with atypical presentation as well as its management, current evaluation by PET-scan and hist...

: A 30-year-old woman presented with lethargy, night sweats, and fever with raised inflammatory markers. Anti-neutrophil cytoplasmic antibody was negative. Abdominopelvic CT was unremarkable. Subsequently, she underwent FDG PET/CT showing globally enlarged kidneys with diffuse hypermetabolic activity within the renal parenchyma bilaterally. Renal biopsies showed morphologic features of an active necrotizing crescentic glomerulonephritis, which was confirmed clinically and treated. This case demo...

AbstractThe definition of primary extranodal lymphoma is rather controversial and often complicated by the variety of lymphoma types. Here we describe FDG PET/CT findings in 3 pediatric patients with diffuse large B-cell non-Hodgkin lymphomas dominated by extranodal lesions involving multiple organs

We report about the usefulness of F-FDG PET for the detection and therapy response evaluation of renal sarcoidosis. A 55-year-old woman presented with a condition diagnosed with pulmonary and ocular sarcoidosis 2 years before having anemia and acute deterioration of renal function. FDG PET revealed diffuse increased FDG uptake in both kidneys and the spleen. Histopathologic examination of a renal biopsy sample revealed granulomatous interstitial nephritis with sarcoidosis. After methylprednisolo...

There is an expanding and exciting repertoire of PET imaging radiotracers for urogenital diseases, particularly in prostate cancer, renal cell cancer, and renal function. Prostate cancer is the most commonly diagnosed cancer in men. With growing therapeutic options for the treatment of metastatic and advanced prostate cancer, improved functional imaging of prostate cancer beyond the limitations of conventional CT and bone scan is becoming increasingly important for both clinical management and d...
