A case of primary gastric undifferentiated high-grade pleomorphic sarcoma diagnosed with chief complaint of fever: a case report and literature review.

Background: Undifferentiated high-grade pleomorphic sarcoma in gastrointestinal tract is extremely rare, and its prognosis is poor.

Case Presentation: An 82-year-old man visited a previous hospital complaining of fever, general fatigue, and shaking chill, for which he received antibiotics therapy. As the fever continued, he was referred to our hospital, where computed tomography and upper gastrointestinal endoscopy showed a 6-cm gastric tumor.

Determinants of extraaortic arterial 18F-FDG accumulation in asymptomatic cohorts: sex differences in the association with cardiovascular risk factors and coronary artery stenosis.

Unlabelled: The objective of this study was to evaluate extraaortic arterial (18)F-FDG accumulation in asymptomatic cohorts by sex and to clarify the association between extraaortic arterial (18)F-FDG accumulation and cardiovascular risk factors (CRFs) and coronary artery stenosis (CAS).

Methods: Five hundred twenty-one asymptomatic individuals (351 men and 170 women) who underwent cancer and CAS screening were enrolled. We evaluated extraaortic arterial (18)F-FDG accumulation in the carotid artery (CA) and iliofemoral artery (IFA) and classified the accumulation patterns into 3 types.

Assessment of FDG retention differences between the FDG-avid benign pulmonary lesion and primary lung cancer using dual-time-point FDG-PET imaging.

Purpose: The aim of this study was to clarify FDG retention differences between FDG-avid benign pulmonary lesions (BPLs) and primary lung cancers (PLCs), and between tuberculous and non-tuberculous BPLs using dual-time-point FDG-PET imaging.

Methods: Thirty-four BPLs and 47 PLCs with a maximal standardized uptake value (SUVmax) >2.5 and a maximal axial diameter >10 mm were enrolled.

FDG-PET/CT findings of peritoneal lymphomatosis.

Peritoneal lymphomatosis (PL) is an extensive lymphomatous infiltration of the intraperitoneal portion of the subperitoneal space, which is a rare presentation of lymphoma. Using CT or MRI findings alone, it is difficult to differentiate between lymphomatosis, carcinomatosis, and other pathological entities.We experienced two PL cases and herein report the FDG-PET/CT findings.

Protein-losing gastropathy with hypertrophic gastric folds: endosonographic findings.

We present a case of protein-losing gastropathy with hypertrophic gastric folds. A 38-year-old man was hospitalized for severe epigastric pain suggestive of hypoproteinemia. Endoscopic and radiologic examination revealed enlarged gastric folds on the greater curvature of the stomach.
