OBJECTIVES: The objectives of this study were to evalute the metabolic characteristics of common malignant space-occupying lesions (SOL) of the brain and to determine the utility of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in differentiating between the common types of malignant brain SOL. PATIENTS AND METHODS: All patients with brain SOL who were referred for an F-FDG PET/CT scan by a multidisciplinary team were included in this retrospective study. The metabolic characteristics of the brain lesions in the form of maximum standardized uptake value (SUVmax) along with tumor-to-background activity ratios were determined and differences were compared using nonparametric statistical tests...

A 53-year-old man had a diagnosis of mucosa-associated lymphoid tissue lymphomas of the dura in the left tentorium. The patient underwent whole-body F-FDG PET/CT and C-methionine PET/CT in order to complete the staging of dural mucosa-associated lymphoid tissue lymphoma. C-methionine uptake was detected in multiple meningeal sites, including left tentorium, with no significant FDG uptake in the same regions.

A 67 year old woman with a 10 year history of rheumatoid arthritis (RA) treated with methotrexate and prednisone, presented with a 2 year history of worsening multiple cutaneous plaques of variable appearance. Two distinct skin lesions were biopsied to reveal a composite cutaneous lymphoma, possibly caused by long term methotrexate therapy. An [18F] fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) was performed to stage the malignancy, and was later repeated to evaluate response to chemotherapy, which guided subsequent management...

Fluorine-18 fluorodeoxyglucose ((18)F-FDG) PET-computed tomography (CT) plays a significant role in diagnosis, staging, therapy selection, and therapy assessment of multiple pediatric malignancies and facilitating precision medicine delivery in pediatric patients. In patients with Hodgkin lymphoma, interim fludeoxyglucose (18)F-FDG PET/CT is highly sensitive and specific for predicting survival and multiple trials with FDG PET/CT-based adaptive therapies are currently ongoing. It is superior to iodine-131 metaiodobenzylguanidine ((131)I-MIBG) scintigraphy and bone scintigraphy for detecting metastases in neuroblastoma patients and sarcoma patients...

Primary intravascular large B cell lymphoma (IVL) remains a diagnostic challenge because of non-specific clinical, laboratory and imaging findings. The aim of the study was to analyse the major characteristics of IVL with uterine involvement. We retrospectively collected features of IVL with uterine involvement that was proven histologically or demonstrated by significant (18)FDG uptake on (18)FDG-PET/CT. Findings were compared to a comprehensive literature review. Five patients were identified. All of them were admitted for fever of unknown origin (FUO), with haemophagocytic lymphohistiocytosis in three cases...

We present a case demonstrating the diagnostic work-up and follow-up of a patient with Chikungunya infection. An (18)F-FDG PET/CT performed four weeks after debut of symptoms revealed pathological (18)F-FDG uptake in enlarged lymph nodes on both side of the diaphragm, and inflammation of both shoulder and hip joints. Lymphoma and infection were the main differential diagnoses. Follow-up (18)F-FDG PET/CT scan in the patient performed 14 weeks after the abnormal scan, revealed almost complete resolution of the metabolically active disease...

A 24-year-old woman who had melena, dizziness, and fatigue and looked pale for 2 months was confirmed to have a microcytic hypochromic anemia in the local hospital. It was further revealed that the patient had splenomegaly and a small intestinal lump, and she was then referred to our hospital. The enhanced CT showed an ileal lesion with enhancement, which showed an increased F-FDG activity in further PET/CT scanning. Lymphoma was therefore suspected, and an uncomplicated surgical resection of the ileal lesion was then performed...

A 73-year-old man presented with fatigue and weight loss. He had CT-proven splenic mass with fistulous connection to the greater curvature of the stomach, which suggested abscess. FDG PET/CT confirmed gastrosplenic fistula in addition to active lymph nodes in the gastrohepatic ligament and epigastric region. Pathological examination after the biopsy of the spleen was consistent with diffuse large B-cell lymphoma. Chemotherapy was administered with close clinical follow-up and resulted in the resolution of fistula without requirement for surgery...

Positron emission tomography with computed tomography (PET-CT) using (18)F- fluorodeoxyglucose (FDG) is an essential part of the management of patients with lymphoma. Efforts to standardize PET acquisition and reporting, including the five-point 'Deauville scale', have enabled PET to become a surrogate for treatment success/failure in common lymphoma subtypes. This review summarizes the key evidence from clinical trials that supports PET-directed personalized approaches in lymphoma. PET-guided therapy has improved outcomes in Hodgkin lymphoma, using less chemotherapy and more selective radiotherapy...

INTRODUCTION: Sclerosing angiomatoid nodular transformation (SANT) of spleen is a new entity defined as a benign pathologic lesion. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) shows weak accumulation, thereby ruling out the malignancy in preoperative diagnosis is difficult. Herein, we reported a case of shrinking SANT with increased FDG accumulation during a 5-year follow-up period, which was treated by laparoscopic splenectomy. PRESENTATION OF CASE: A 64-year-old female had been referred to our hospital for the evaluation of a splenic tumor...

In order to investigate whether the SUVmax-liver-based interpretation could improve prognostic accuracy of interim (PET-4) and posttreatment PET/CT (PET-end), 115 patients with newly diagnosed DLBCL were recruited in the study. ROC analysis revealed the optimal threshold is 1.6-fold of SUVmax-liver for PET-4 and 1.4-fold of SUVmax-liver for PET-end. The SUVmax-liver-based interpretation had a perfect interobserver agreement, higher prognostic accuracy and positive predictive value than 5-point scale and %ΔSUVmax criteria in both PET-4 and PET-end...

A 55-year-old man with large B-cell lymphoma developed atraumatic left shoulder pain. F-FDG PET/CT revealed new left supraspinatus and infraspinatus muscle uptake while the initial disease resolved. Given the discrepancy between initial disease treatment response and new left shoulder findings, an MRI scan was performed. This demonstrated diffuse supraspinatus and infraspinatus muscle edema and enhancement with no focal lesion. Muscle biopsy was negative for lymphoma, but features of muscle denervation were seen...
