We report a case of esophageal intramural pseudodiverticulosis associated with an inflammatory esophageal mass with high F-fluorodeoxyglucose (FDG) uptake. A 48-year-old man presented with dysphagia caused by an esophageal stricture. Positron emission tomography/magnetic resonance imaging showed an FDG-avid lesion in the lower esophagus. Due to suspected malignancy, the patient underwent subtotal esophagectomy. Histological examination confirmed the diagnosis of an inflammatory tumor associated with esophag...
A 61-year-oldman presentedwith a chief complaint of abdominal pain. Enhancedcomputed tomography andmagnetic resonance imaging showeda left adrenal mass with a diameter of 7 cm with heterogeneous enchancement. He was referredto our hospital for further treatment. No endocrinological abnormality was detected. The tumor showed abnormal uptake on fludeoxyglucose positron emission tomography scan. Preoperative diagnosis was left adrenocortical carcinoma (cT2N0M0). Tumor excision was performedandpathological find...
A 35-year-old man wasreferred to our hospital for treatment of a right adrenal tumor detected by ultrasonography during a physical check-up. Contrast-enhanced abdominal computed tomography revealed a poorly enhanced 74 mm tumor situated adjacent to the upper pole of the right kidney. The tumor consisted of fat with peripheral calcification. Magnetic resonance imaging also revealed a right retroperitoneal tumor with fatty contents and well-circumscribed capsule. The endocrine examination revealed the tumor a...
Distinguishing adrenal incidentalomas (5% of all abdominal CT scans) from metastasis is a frequent diagnostic challenge in primary malignancies with a propensity for adrenal spread, such as lung cancer. Adrenal myelolipoma and adenoma can be definitively characterized as benign by demonstrating gross and microscopic fat, respectively, on CT and MRI and an absence of abnormal uptake on PET. Unfortunately, adrenal sampling is frequently necessary in indeterminate cases for adequate staging of extra-adrenal pr...
This study investigated the relationship of fluorine-18-fluorodeoxyglucose (F-FDG) uptake of bone marrow (BM) on PET/computed tomography (PET/CT) with clinicopathologic factors and survival in patients with colorectal cancer.
Increased FDG uptake in morphologically normal adrenal glands on PET-CT is a diagnostic challenge with major implications on treatment. The purpose of this retrospective study was to report our experience of CT-guided percutaneous core biopsy of morphologically normal adrenal glands showing increased FDG uptake in a context of lung cancer.
Previous studies have shown that the majority of patients with PMR have increased 18F-fluorodeoxyglucose (FDG) uptake around the shoulders, hips and processes of the cervical and lumbar spine on PET. The specificity of these findings for PMR is, however, not known.
Purpose To examine the effect metabolic burden (tumor and/or cardiac myocyte uptake) has on fluorine 18 fluorodeoxyglucose (FDG) distribution in organs and tissues of interest. Materials and Methods Positron emission tomographic (PET)/computed tomographic (CT) scans at the Ann Arbor Veterans Affairs hospital from January to July 2015 were reviewed. A total of 107 scans (50 patients; mean age, 64.3 years ± 13.2 [standard deviation]) had metabolic tissue burden assessed by using total lesion glycolysis (TLG)...
F-18 fluorodeoxyglucose (FDG) PET/CT has several advantages in diagnosis of cancer of unknown primary with reported incremental diagnostic value. In this study, we evaluated the patients who were presented with multiple brain metastasis and unknown primary tumor.
Lymph node stage prior to treatment is strongly related to disease progression and poor prognosis in non-small cell lung cancer (NSCLC). However, few studies have investigated metabolic imaging features derived from pre-radiotherapy 18F-fluorodeoxyglucose (FDG) positron-emission tomography (PET) of metastatic hilar/mediastinal lymph nodes (LNs). We hypothesized that these would provide complementary prognostic information to FDG-PET descriptors to only the primary tumor (tumor).
Pancreatic neuroendocrine tumors are rare. Treatment includes aggressive local management of the primary lesion and metastases, and systemic somatostatin. This is the first report of an isolated metachronous metastasis to the adrenal gland from a pancreatic neuroendocrine tumor that presented 90 months after the primary tumor.
Black adrenal adenoma (BAA) is a rare, benign adrenal lesion with a black or brown appearance. This is the first report of this lesion in a patient with a synchronous esophageal cancer and highlights the importance of considering a false positive finding on a Positron Emission Tomography (PET) scan, which might otherwise preclude resection.
Adrenal gland volume is associated with survival in septic shock. As sepsis and post-cardiac arrest syndrome share many pathophysiological features, we assessed the association between adrenal gland volume measured by computerized tomography (CT)-scan and post-cardiac arrest shock and intensive care unit (ICU) mortality, in a large cohort of out-of-hospital cardiac arrest (OHCA) patients. We also investigated the association between adrenal hormonal function and both adrenal gland volume and outcomes.
Tumor thrombosis is a relatively uncommon complication of renal cell carcinoma (RCC), and its diagnosis has therapeutic and prognostic implication. Computerized tomography (CT) is the primary imaging modality for staging RCC, but it has low sensitivity to differentiate between tumor thrombus and bland or benign thrombus. 18-fluorodeoxyglucose positron emission tomography/CT (PET/CT) has a limited role in diagnosis and staging of RCC, but its diagnostic accuracy is considerably high for detection of metaboli...
To determine whether intraprocedural fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) is predictor of local tumor progression after percutaneous ablation of colorectal liver metastases.In this IRB-approved prospective study, 39 patients (19 males, 20 females; median age 56 years) underwent split-dose FDG PET/CT-guided ablation followed by immediate biopsy and contrast-enhanced CT imaging of the ablation zone. Binary categorization of biopsy tissues was performed based on pr...
Most solid tumors are hypoxic in nature due to the limited supply of oxygen to internal tissues. Hypoxia plays an important role in metabolic adaptations of tumors that contribute significantly to cancer pathogenesis. Among the several metabolic alterations induced by hypoxia, hypoxia-mediated increased glucose uptake serves as the hallmark of metabolic reprogramming. Hypoxia-mediated stabilization of hypoxia-inducible factor-1 alpha (HIF-1α) transcription factor leads to altered expression of several gl...
To analyze our experience in retroperitoneal laparoscopic adrenalectomy (RLA) with transient renal artery occlusion for large adrenal tumors (≥8 cm) and to explore the safety and feasibility of this surgical procedure.
Congenital adrenal hyperplasia (CAH) patients are at risk for life-threatening adrenal crises. Management of illness episodes aims to prevent adrenal crises.
A high prevalence of insulin resistance (IR) has proven to manifest in patients with adrenal incidentalomas (AI). It has been demonstrated that an increase in IR is related to the size of tumourous masses; additionally, luteinizing hormone (LH) dependent adrenal pathologies are well documented in patients with LH responsive adrenal tumours occurring under conditions of physiologically elevated LH. We hypothesized that an association between LH and insulin might play a role in adrenal tumourigenesis and ster...
This study investigated the prognostic value of diffuse splenic uptake on F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) in gastric cancer (GC) patients.
The accumulation, dissemination and clearance of monoclonal antibody-based therapeutics or imaging reagents targeting tumor associated antigens is governed by several factors including affinity, size, charge, and valency. Tumor targeting antibody fragments have distinct advantages over intact monoclonal antibodies such as enhanced penetration within the tumor and rapid accumulation but are subject to rapid clearance. Polyethylene glycol (PEG)-modified antibody fragments can provide a way to balance tumor pe...
To determine if there are differences in overall survival (OS) or event-free survival (EFS) in patients with and without concomitant extra-adrenal metastases undergoing adrenal metastasectomy.
A 62-year-old man with recently diagnosed prostatic adenocarcinoma was referred for a whole-body Ga-prostate-specific membrane antigen (PSMA) PET/CT scan for staging. Although the scan did not reveal metastatic disease, it did reveal a PSMA-avid lesion in the upper abdomen located between the liver and the stomach. Histopathologic examination demonstrated a gastrointestinal stromal tumor. The lesion demonstrated increased uptake in the margins of the tumor with a central photopenic area, which we consider t...
Capsinoids activate brown adipose tissue (BAT) with increased energy expenditure associated with subthreshold 18-fluorine fluorodeoxyglucose uptake in BAT-positive humans confirmed by positron emission tomography scan.
Capsinoids are reported to increase energy expenditure (EE) via brown adipose tissue (BAT) stimulation. However, imaging of BAT activation by capsinoids remains limited. Because BAT activation is a potential therapeutic strategy for obesity and related metabolic disorders, we sought to prove that capsinoid-induced BAT activation can be visualized by 18-fluorine fluorodeoxyglucose (18F-FDG) positron emission tomography (PET).
