Primary cardiac tumors are rare with angiosarcoma being the most common among malignant cardiac tumor. We present a case of 30-year-old female patient in whom F-18-fluorodeoxyglucose positron emission tomography/computed tomography demonstrated a necrotic mass in right atrium with multiple fluorodeoxyglucose avid lesions in both upper and lower alveolus, liver, multiple bones, and bilateral lun...

A 40-year-old Japanese man with acquired immunodeficiency syndrome was diagnosed with Kaposi sarcoma (KS) on the basis of the results of skin lesion biopsies. In addition, 18F-fluorodeoxyglucose-position emission tomography-computed tomography revealed abnormal fluorodeoxyglucose uptake in KS lesions, whereas gallium-67 scintigraphy did not show uptake of gallium. These findings indicate that c...

INTRODUCTION Hodgkin's disease is highly curable by radiotherapy and/or chemotherapy, but refractory disease or early relapses are rarely cured by conventional salvage therapy. CASE PRESENTATION We report a case of a 20-year-old Caucasian man, with a biopsy-proven intrapulmonary relapse of Hodgkin's disease, for whom salvage chemotherapy was administered. During salvage chemotherapy intense i...

We report two cases of young women with a solid pseudo-papillary tumor of the pancreas which having cystic and hemorrhagic components with marked calcification on computed tomography and magnetic resonance imaging. F-18 fluorodeoxyglucose positron emission tomography revealed abnormally increased accumulation of F- 18 fluorodeoxyglucose in the pancreas tail tumors, especially in the non-calcifi...

We treated a patient with inflammatory pseudotumor of the mediastinum that exhibited high uptake of fluorodeoxyglucose on positron emission tomography. A 69-year-old male patient was diagnosed with a mass measuring 70 mm in diameter in the anterior mediastinum as revealed by computed tomography. The lesion showed strong uptake of 18-fluorine fluorodeoxyglucose with a maximum standardized uptake...

INTRODUCTION 18-Fluorodeoxyglucose positron emission tomography can detect the pulmonary involvement of intravascular lymphoma that presents no abnormality in a computed tomography scan. CASE PRESENTATION We report the case of a 61-year-old Japanese man who had pulmonary intravascular lymphoma and no computed tomography abnormality. We were able to make an antemortem diagnosis of pulmonary in...

OBJECTIVE To correlate the quantitated tumor vascularity of implanted murine tumors as depicted by contrast-enhanced sonography with estimates made with magnetic resonance imaging and with estimates of the percentage of viable (metabolically active) tumor as depicted by fluorodeoxyglucose autoradiography. METHODS Implanted tumors in 10 mice were imaged with contrast-enhanced sonography, magne...

Askin tumor is a rare disease which had previously been reported as being thallium-201 and gallium-67 avid. Varying data regarding 18F- fluorodeoxyglucose metabolism has been described with Ewing family of soft tissue tumors. In this case, we present a patient found to have an Askin tumor of the left chest wall which demonstrated indium-111 pentetreotide and technetium-99m MIBI avidity. The les...

Introduction: Pulmonary hamartomas are the most common benign tumors of the lung. It usually shows no FDG uptake and has a low risk for malignant transformation. We present a rare case of pulmonary hamartoma with low Fluorodeoxyglucose uptake to call attention to the low malignancy potential of this benign tumor. Case presentation: 67-year old male patient on the preoperative evaluation for his...

BACKGROUND Fluorine-18-fluorodeoxyglucose uptake on positron emission tomography is reported to have prognostic significance in patients after resection of lung adenocarcinoma. However, its relationship with histopathologic features remains unknown. METHODS We conducted a retrospective analysis of 205 patients who had undergone surgical resection of primary lung adenocarcinoma (> 1.0 cm) afte...
