intravascular large b-cell lymphoma (ivlbcl) is a rare and aggressive subtype of systemic extranodal non-hodgkin diffuse large b-cell lymphoma (dlbcl). we report a rare case of ivlbcl who showed diffuse 18f-fluorodeoxyglucose (fdg) uptake in the lung in fdg-positron emission tomography/computed tomography (pet/ct) without respiratory symptoms or chest ct abnormalities. serum biochemical studies...

Eccrine carcinoma is an extremely rare malignant skin cancer arising from eccrine sweat glands with a high metastatic potential. It mainly occurs in the elderly, with equal incidence in both sexes. It usually spreads to regional lymph nodes, with liver, lungs, and bones being the most common sites of distant metastasis. Because of tumor rarity, little is known about the value of F18- FDG PET/CT...

Objective(s): The aim of this study was to analyze detection rates and effectiveness of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) cancer screening program for prostate cancer in Japan, which is defined as a cancer-screening program for subjects without known cancer. It contains FDG-PET aimed at detection of cancer at an early stage with or without additional screening tests ...

A 55-year-old man presented with upper abdominal discomfort. Abdominal computed tomography (CT) and a colonoscopic biopsy revealed non-Hodgkin lymphoma of the ileocecal region. An FDG-PET/CT scan performed three days after colonoscopy demonstrated intense FDG activity in the right abdomen on a maximal projection PET image (Picture 1). There were no other foci of abnormal FDG activity. The CT po...

Heterotopic ossification is the calcification of the soft tissues with increased calcium accumulation in that tissue. The imaging characteristics are well defined because it is a well-known documented entity. However the metabolic characteristics are less well known due to the relatively recent development of the PET/CT modality. Previous reports in tissues elsewhere the body confirms that the ...

(18)F-FDG PET/CT imaging is an established imaging modality for cancer staging and response assessment. Its role in identifying infective and inflammatory pathologies from malignancy is debated. Dual time - point imaging is a refined technique used to overcome this interpretational dilemma. We present a 59 year old male with an unknown primary malignancy who was referred for a (18)F-FDG PET/CT ...

FDG-PET has changed lymphoma management at staging and for response assessment due to its capability to improve disease characterization and treatment selection. New recommendations have been made by the ICML working group in 2014. FDG-PET is now recommended for staging in the vast majority of lymphoma since almost all types of lymphoma are FDG-avid. It has been shown recently that FDG-PET due ...

Kikuchi-Fujimoto disease (KFD) is a benign but self-limiting disorder. However, KFD is often misdiagnosed as a malignant disease. Although 18F-fludeoxyglucose (FDG) uptake on dual-time-point imaging (DTPI) positron emission tomography (PET)/computed tomography (CT) is useful in distinguishing malignant from benign disease, the latter sometimes mimics malignancy on DTPI PET/CT, resulting in a mi...

Objective(s): We aim to investigate the clinical impact of 18F-FDG PET/CT in managing patients with gynecological malignancies and pelvic or extrapelvic lymph nodes that are of equivocal significance on conventional imaging.Methods: We retrospectively evaluated 18F-FDG PET/CT scans of patients with gynecologic tumors who were referred to King Hussein Cancer Center from January 2010 to August 20...
