We present a 77-year woman with a size of 9.5x9x7cm giant ancient schwannoma located in the lower arm. Increased activity accumulation in the tumor was seen on the Tc-99m-methylene diphosphonate bone scintigraphy. After excision of the tumor, Pathologic diagnosis could be illustrated as an ancient schwannoma. Previous studies reported that Schwannoma could be demonstrated with increased Tc-99m-...

Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...

 Parathyroid adenoma involving a single parathyroid gland is the underlying cause of 80-85% of primary hyperparathyroidism (PHPT). Skeletal system is significantly affected by PHPT. Brown tumors are known to have affinity for 99mTc-MIBI. We report a rare case of PHPT presenting with diffuse bony pain, high calcium level and significantly elevated alkaline phosphatase level. 99m<...

Visualization of the kidneys during hepatobiliary scintigraphy using technetium-99m(Tc) labeled N -substituted iminodiacetic acid agents is often the consequence of severe hepatic dysfunction or biliary tract obstruction {}-3). We report a case of delayed renal visualization seen during hepatobiliary imaging with [Tc]diisopropyl-iminodiacetic acid (DISIDA) where no evidence for severe hepatic d...

Meckel's diverticulum is a common congenital disorder which may result in Gl bleeding. For definite diagnosis before surgery, radiographic procedures such as small intestine barium studies are not greatly successful; on the other hand Tc-99m-Pertechnetate imaging is a physiologic and noninvasive method with high sensitivity and specificity. In this report, three patients with rectorrhagia...

BACKGROUND In this study, we sought to identify definitive biomarkers associated with disease activity in primary Sjögren's syndrome (pSS). METHODS Serum protein concentrations in pSS patients and healthy controls (HCs) were comprehensively screened using high-throughput proteomic analysis, and differentially expressed proteins were extracted. Correlation between differentially expressed prot...

INTRODUCTION Ileal duplications are encountered infrequently in adults, because symptoms including abdominal pain, intussusception, hemorrhage, and perforation usually present in early childhood. In this report, we present an adult case of ileal duplication that was revealed by double-balloon endoscopy (DBE). CASE DESCRIPTION A 73-year-old Japanese man presented with anemia and melena. Anal D...
