Extensive avid FDG Lymphadenopathy

William Makis, Mark Palayew, Christopher Rush, Stephan Probst
A 60-year-old female with no significant medical history presented with hematuria. A computed tomography (CT) scan revealed extensive lymphadenopathy with hypodensities in the liver and spleen, and she was referred for an 18 F-fluorodeoxyglucose (18 F-FDG) positron emission tomography/CT (PET/CT) study to assess for malignancy of unknown primary. PET/CT revealed extensive 18 F-FDG avid lymphadenopathy as well as innumerable intensely 18 F-FDG avid lung, liver and splenic nodules, highly concerning for malignancy...

A 44-year-old man presented with fever (low to high grade) for 2-month duration despite treatment with oral antibiotics and antipyretics. Further, enquiry did not yield any potentially explanatory clues to a diagnosis. Physical examination revealed only left axillary lymphadenopathy, but was otherwise unremarkable. A number of diagnosis included tuberculosis, malignancy, lymphoma, connective disease disorder and infective endocarditis. Further evaluation revealed severe anaemia due to iron deficiency which was supported with blood transfusion and oral iron supplementation...

Mental nerve neuropathy is usually due to local trauma or dental causes, but may be a manifestation of malignancy. A patient with virologically controlled human immunodeficiency virus (HIV) infection presented with a 'numb chin' on the background of long-standing night sweats, malaise and weight loss, worsening respiratory symptoms, and lymphadenopathy. Burkitt non-Hodgkin lymphoma was diagnosed from histology of a lymph node. Imaging (magnetic resonance imaging and 18 fluorodeoxyglucose [FDG]-positron emission tomography-computed tomography [PET-CT]) showed abnormal intracranial enhancement of the right mandibular nerve and extensive 18 FDG-avid lymphadenopathy above and below the diaphragm, focal lesions in the spleen and within the right mandible...

Chronic nonbacterial osteomyelitis is a rare entity of unknown etiology and most likely an autoinflammatory disease. A 45-year-old man complained of a growing painful mass of the right chest wall. FDG PET/CT demonstrated a large destructive rib lesion with intense uptake and extensive FDG avid lymphadenopathy, which mimicked a malignant or metastatic disease. Both CT guided core-needle and excisional biopsies showed reactive/regenerative/granulomatous changes coupled with focal neutrophils and marrow atrophy, consistent with chronic osteomyelitis...

SESSION TITLE: Cancer Student/Resident Case Report Posters IIISESSION TYPE: Medical Student/Resident Case ReportPRESENTED ON: Tuesday, October 28, 2014 at 01:30 PM - 02:30 PMINTRODUCTION: Primary pulmonary leiomyosarcomas (PPPLS) are exceptionally rare tumors and constitute only 0.2-0.5% of the total lung cancers. Sarcomas metastasizing to brain or heart are rare and PPPLS, with metastases to both have never been reported to our knowledge . Here, we present a case of high-grade PPPLS with brain and cardiac metastases...

Endometrial cancer is the most common gynecologic and the fourth most common malignancy in women in the United States. Cross-sectional imaging plays a vital role in pretreatment assessment of endometrial cancers and should be viewed as a complementary tool for surgical evaluation and planning of these patients. Although transvaginal US remains the preferred examination for the screening purposes, MRI has emerged as the modality of choice for the staging of endometrial cancer and imaging assessment of recurrence or treatment response...

BACKGROUND: [18F]Fluorodeoxyglucose (FDG) positron emission tomography (PET) is a powerful tool for the imaging of various lymphomas. Despite its high FDG avidity, there is little data on PET in follicular lymphoma (FL). In this work, we present findings concerning PET at staging and posttreatment evaluation in FL. PATIENTS AND METHODS: A total of 181 PET scans were evaluated in 117 patients with FL in a retrospective study. Positron emission tomography-based results were compared with conventional staging in 82 patients...

A patient who presented with weight loss and recurrent left lower lobe pneumonia was diagnosed with endobronchial carcinoid. Chest CT scan demonstrated extensive mediastinal and hilar lymphadenopathy suggesting stage IIIB disease, but radionuclide imaging with In-111 pentetreotide and F-18 FDG PET diagnosed 2 distinct pathologic processes based on functional differences between neuroendocrine tumors (expressing somatostatin receptors) and sarcoidosis (intensely FDG-avid). The possible association of carcinoid with sarcoidosis and sarcoid-like reactions in regional lymph nodes should always be considered, and the staging process should include both anatomic and functional imaging and biopsy confirmation of suspected metastatic lesions...
