BACKGROUND We hypothesized that postural instability and cognitive decline in patients with Richardson’s syndrome could be a consequence of reduced thalamic and frontal metabolism. Severe Parkinsonian signs in patients with progressive supranuclear palsy-parkinsonism may be reflected by alterations in putaminal metabolism. METHODS Eleven patients with Richardson’s syndrome, 8 patients with pr...

Adrenal angiomyolipoma is an extremely rare tumor, although computed tomography (CT) or magnetic resonance imaging findings of adrenal angiomyolipoma have been reported, there are no reports regarding integrated fluorine-18-fluorodeoxyglucose positron emission tomography and computed tomography ((18)F-FDG PET/CT) imaging. We report a case of adrenal angiomyolipoma showing a significantly high u...

CONTEXT An intraductal oncocytic papillary neoplasm is a rare pancreatic tumor with the potential of developing invasive carcinoma. Its differentiation from other cystic-like neoplasms of the pancreas, such as intraductal papillary mucinous neoplasms, is a challenge for pancreatic imaging. CASE REPORT We present the case of a 76-year-old male with painless jaundice caused by an intraductal on...

We report a case of ganglioneuroma with abnormal 18F-fluorodeoxyglucose (FDG) uptake. A 26-year-old woman presented to the hospital with a slowly growing abdominal tumor without symptoms. She was diagnosed with neuroblastoma in childhood and treated by surgery and chemotherapy. Computed tomography (CT) revealed huge retroperitoneal tumors and fused 18F-fluorodeoxyglucose positron emission tomog...

The routine use of (18)F-fluorodeoxyglucose-positron emission tomography (PET)/computed tomography scans for staging and assessment of treatment response for cancer has resulted in a large number of thyroid abnormalities being detected as incidental findings ("incidentalomas"). Since most PET/CT scans are performed in the setting of a known nonthyroid malignancy, the need for "incidentalomas" t...

We tested the hypothesis that extent of severe hypometabolism measured by fluorodeoxyglucose PET has a U-shaped (nonlinear) relationship to IQ in children with unilateral Sturge-Weber syndrome. Thirty-five consecutive children (age range: 30-153 months) with Sturge-Weber syndrome and unilateral brain involvement were enrolled in the study. Participants underwent cognitive assessment and interic...

Atherosclerotic burden has become the focus of cardiovascular risk assessment. PET/computed tomography (CT) imaging with tracers 18F-fluorodeoxyglucose and 18F-sodium fluoride shows arterial wall inflammation microcalcification, respectively. Arterial uptake both is modestly age dependent. consistently associated factors more easily measured in heart. Because extremely high sensitivity, ultrash...

in this report, we have presented 18fdg-pet findings of organized hematoma of the maxillary sinus (ohms) that showed an increased fdg uptake in the peripheral rim of the mass with central photopenia. to our knowledge, this is the first case report in the literature reporting fdg-pet/ct findings of ohms. careful interpretation of metabolic (fdg-pet/ct) and anatomic (ct and mri) images should be ...

Fluorodeoxyglucose (FDG) whole body positron emission computed tomography (PET-CT) detects clinically occult malignancy. The aim of this study was to assess the prevalence and significance of focal thyroid 18F - fluorodeoxyglucose uptake. A retrospective review of all patients who had FDG PET-CT examinations, in a single tertiary referral centre was performed. PET scan findings and the final pa...
