OBJECTIVE: To evaluate whether positron emission tomography/computed tomography using fluorine-18 fluoro-deoxyglucose ((18)F-FDG PET-CT) predicts bone marrow involvement (BMI) in pediatric Hodgkin's lymphoma (pHL) with sufficient accuracy to supplant routine staging bone marrow biopsy (BMB), and to assess the clinical importance of marrow disease by comparing the prognosis of stage IV HL with BMI versus that without BMI. METHODS: Data were retrospectively analyzed for all cases of pHL between July 2010 and June 2015 referred for staging (18)F-FDG PET-CT scan and BMB...

PURPOSE: Primary bone lymphoma (PBL) is one of the rarest primary bone malignancies. Very limited data are available on the role of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in PBL. PATIENTS AND METHODS: Overall, 16 relevant patients had F-FDG PET/CT for staging or staging/restaging PBL. The cases with extraskeletal lesions such as lymphadenopathy or with osseous involvements in disseminated lymphoma were excluded on the basis of the definition of PBL. F-FDG PET/CT findings were correlated to pathologic and/or anatomic image information...

Chronic lymphocytic leukemia (CLL) is a low-grade B-cell proliferative disease with a generally indolent course. In a few cases, it undergoes transformation and becomes a more aggressive malignancy, such as diffuse large B-cell lymphoma (DLBCL). This process, which is called Richter transformation (RT), is often detected too late and is associated with a poor prognosis. There are multiple molecular diagnostic approaches to detect RT in preexisting CLL. Metabolic imaging using 18-fluorine fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT) can be a very useful tool for early detection of RT and which can hence allow for timely intervention, thereby improving the patient's chances of survival...

Bleomycin is an antineoplastic agent causing fatal pulmonary toxicity. Early diagnosis of bleomycin-induced pneumonitis is crucial to prevent irreversible damage. Pulmonary function tests are unreliable for identifying risk of bleomycin toxicity. Fluorodeoxyglucose PET/CT scanning can reveal inflammation secondary to pneumonitis but is not sufficiently specific for diagnosis. We retrospectively analyzed scans from 77 patients with Hodgkin lymphoma (median age 41 years, mean bleomycin dose 134 mg) to evaluate bleomycin-induced pneumonitis...

An 84-year-old man with a history of diffuse large B-cell lymphoma in remission who had completed chemotherapy 3 years previously was referred for imaging evaluation of disease recurrence. Abnormal accumulation in the left scrotum was demonstrated on F-FDG PET/CT. Subsequent ultrasonography showed a nodular mass lesion in the left epididymis. He then underwent left orchiectomy. Histopathological examination of the mass diagnosed smooth muscle hyperplasia/hamartoma of the left epididymis. Epididymal smooth muscle hyperplasia/hamartoma should be included as a differential diagnosis for malignant scrotal tumor...

The introduction of hybrid PET/MRI imaging using integrated systems into clinical practice has opened up the possibility of reducing the radiation dose from hybrid imaging by eliminating the contribution from computed tomography. Studies comparing the possibilities of PET/CT and PET/MRI imaging demonstrated it is possible to use the advantages of the high contrast resolution of magnetic resonance for soft tissue and bone marrow along with PET records in a quality comparable to PET/CT imaging. The significant feature for PET imaging in Hodgkińs lymphoma is that it is a tissue with high levels of radiopharmaceutical accumulation, which decreases proportionally after successful therapeutic effect, the effect of therapy is assessed using Deauville score system on interim examinations...

RATIONALE: Positron Emission Tomography/Computed Tomography (PET/CT)-ascertained bone marrow involvement (BMI) constitutes the single most important reason for upstaging by PET/CT in Hodgkin lymphoma (HL). However, BMI assessment in PET/CT can be challenging. This study analysed the clinico-pathological correlations and prognostic meaning of different patterns of bone marrow (BM)-Fluorodeoxyglucose (FDG)-uptake in HL. PATIENTS AND METHODS: 180 newly diagnosed early unfavourable and advanced stage HL patients, all scanned at baseline and after 2 Adriamycin-Bleomycin-Vinblastine-Dacarbazine (ABVD) courses with FDG-PET, enrolled in two International studies aimed at assessing the role of interim PET scan in HL, were retrospectively included...

PURPOSE: We performed a retrospective analysis to evaluate the usefulness of positron-emission tomography/computed tomography (PET/CT) findings in the classification and management of anterior mediastinal tumors. METHODS: Between 2006 and 2015, 105 patients with anterior mediastinal tumor received PET/CT. (18)F-fluorodeoxyglucose ((18)F-FDG)-PET images were obtained 60 minutes after the injection of (18)F-FDG. RESULTS: The histological classifications were as follows: thymoma (n = 49), thymic carcinoma (TC) (n = 19), malignant lymphoma (ML) (n = 8), teratoma (n = 7), thymic cyst (n = 14), and others (n = 8)...

Primary effusion lymphoma (PEL) is a rare type of non-Hodgkin's lymphoma presenting as a lymphomatous effusion and absence of a solid tumor mass. Extracavitary PEL (EC-PEL) is a subtype of PEL with the absence of an effusion but presence of solid tumor. PEL and EC-PEL share the same histopathologic and immunophenotypic features. Kaposi sarcoma-associated herpesvirus (KSHV) positivity is seen universally in these malignancies and is a requisite for diagnosis. Most cases are seen to occur in HIV positive individuals...

Positron emission tomography-computed tomography (PET/CT) is widely used for initial staging and monitoring treatment responses in Hodgkin and diffuse large B-cell lymphoma. However, its prognostic value in extranodal natural killer (NK)/T-cell lymphoma (ENKL) remains unclear. Here, we conducted a retrospective study to determine the impact of PET/CT in ENKL. Fifty-two patients newly diagnosed with ENKL were enrolled. Baseline maximum standardized uptake values (SUVmax), whole-body metabolic tumor volume (WBMTV) and whole-body total lesion glycolysis (WBTLG) were recorded...

Evaluation of bone marrow involvement (BMI) is paramount in diffuse large B-cell lymphoma (DLBCL) for prognostic and therapeutic reasons. PET/CT scanner (PET) is now a routine examination for the staging of DLBCL with prognostic and therapeutic implications. This study evaluates the role of PET for detecting marrow involvement compared to bone marrow biopsy (BMB). This monocentric study included 54 patients diagnosed with DLBCL between 2009 and 2013 and who had FDG PET/CT in a pre-treatment setting. A correlation analysis of the detection of BMI by PET and BMB was performed...

OBJECTIVE: The purpose of this study is to analyze the (18)F-FDG PET/CT features of solid renal masses detected in patients with lymphoma and to evaluate the ability of PET/CT to differentiate renal cell carcinoma (RCC) from renal lymphomatous involvement. MATERIALS AND METHODS: Thirty-six patients with solid renal masses on PET/CT performed for staging or follow-up of lymphoma were evaluated retrospectively. The features recorded for each renal mass included the following standardized uptake values (SUVs) on PET/CT: the maximum SUV (SUVmax), the mean SUV (SUVmean), the ratio of the SUVmax of the tumor to that of the normal kidney cortex, the ratio of the SUVmean of the tumor to that of the normal kidney cortex, the ratio of the SUVmax of the tumor to that of the normal liver, and the ratio of the SUVmean of the tumor to that of the normal liver...

In Part 1, we reviewed the role of interim positron emission tomography (PET)/CT scans in Hodgkin lymphoma. In advanced Hodgkin lymphoma, interim PET is a useful prognostic tool that can be used to implement risk-adapted therapy with potential benefits for both patients who have negative interim scans and those whose scans are positive. Interim PET/CT has not shown as encouraging results in diffuse large B-cell lymphoma (DLBCL), with the exception of germinal center B-cell DLBCL. Thus, quantitative methods of interpreting interim PET scans have been pursued in an effort to improve their predictive value...

Bruce D Cheson, Lale Kostakoglu
Interim positron emission tomography (PET)/CT has shown encouraging results when used as a prognostic tool early in the course of treatment of advanced Hodgkin lymphoma, allowing for a reduction in treatment for patients with favorable characteristics, while suggesting a benefit from changing therapy for those with a positive scan. For patients with limited disease, a negative scan allows for a decrease in treatment; however, the benefits for those patients whose scans are positive are less certain. Here we critically analyze the role of PET/CT in the early assessment of Hodgkin lymphoma...

PURPOSE: In early-stage classical Hodgkin lymphoma, fluorodeoxyglucose positron emission tomography (PET)-computed tomography (CT) scans are performed routinely after chemotherapy, and the 5-point Deauville score is used to report the disease response. We hypothesized that other PET-CT parameters, considered in combination with Deauville score, would improve risk stratification. METHODS AND MATERIALS: Patients treated for stage I to II Hodgkin lymphoma from 2003 to 2013, who were aged ≥18 years and had analyzable PET-CT scans performed before and after chemotherapy, were eligible...

An asymptomatic 26-year-old man received an annual medical check-up, and chest X-ray showed a protrusion of the aortopulmonary window. Chest computed tomography (CT) revealed an anterior mediastinal tumor and cysts with thin wall and septum enhancement. The preoperative diagnosis was cystic thymoma or malignant lymphoma. We performed total resection of the tumor through a median sternotomy. The pathological findings revealed seminoma, positive for c-kit stain, and multilocular thymic cysts. Cysts were lined by normal squamous epithelium and no seminoma cells were located on their surface...
