A 25-year-old patient with osteosarcoma of the right distal femur underwent a bone scintigraphy with Tc-99m methylene diphosphonate (MDP). Whole-body bone scan revealed extensive metastatic disease in the abdominal region. Abdominal computerized tomography confirmed the presence of ascites and calcified masses on the greater omentum and peritoneal surfaces. Here we describe a case of unusual me...

department, Tri-Service General Hospital, Taiwan, with diffuse abdominal pain for one day in April 2012. Her abdomen was distended, hypoactive and tender without palpable masses. Abdominal plain radiograph showed intestinal obstruction (Fig. 1). The computed tomography (CT) of abdomen demonstrated incarceration of the small bowel into the left obturator foramen (Fig. 2). An obturator hernia wit...

INTRODUCTION A 55-year-old woman with a 3-month history of abdominal pain presented to the emergency department with chief complaints of worsening abdominal pain and per os intolerance since 3 days ago. Her medical history was noteworthy for watery diarrhea without fever, loss of appetite, weight loss, and nausea and vomiting. Examination revealed abdominal tenderness over right and left lower ...

The probabilistic Noisy OR model has been widely used as a means of reducing the amount of probabilistic information that is needed to specify the interaction between groups of variables. Motivated by our work on the diagnosis of faults in satellite subsystems , which required a similar synthesis of partial possibilistic information on interactions , we consider a number of ways of gener-alisin...

Endoscopic ultrasound gives high resolution images of the mediastinum and abdominal organ improves visualization for obtaining tissue sample cytology. In our study 112 subjects underwent EUS guided FNAC, out them 51 were diagnosed as carcinoma (45.5%), 15 tuberculosis (13.39%), reactive adenitis is 13 (11.6%), other benign disease 27 (24.1%). So overall diagnosis we made in (106/112) (94.6%). 6...

Desmoid tumor (DT) is a locally invasive form of fibromatosis, comprising only 0.03% of all tumors. DTs occur more frequently in patients with familial adenomatous polyposis and Gardner's syndrome, as intra-abdominal or anterior abdominal wall tumors, whereas sporadic DTs are more likely to be extra-abdominal (only 5% of sporadic DTs are intra-abdominal). There is also an association of DTs wit...

A 57-year-old woman was admitted to our hospital with abdominal pain and vomiting. Her abdomen was distended, and obstructive bowel sounds were discovered on examination. Diffuse abdominal tenderness was present, but no palpable masses were apparent. Abdominal computed tomography confirmed a large gallstone obstructing the small bowel. Colonoscopy revealed a large gallstone lodged at the termin...

A 34-year-old black woman was being evaluated for vaginal bleeding as an outpatient when abnormal findings on chest roentgenogram were noted (Fig 1). She complained only of vague abdominal discomfort and had no respiratory complaint. Her past medical history was significant for menometrorrhagia in 1981 which resulted in an abdominal hysterectomy. The ovaries were left intact. She was receiving ...

Desmoplastic small round cell tumors (DSRCTs) are rare and aggressive malignant tumors. The aim of the present study was to analyze computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FDG-PET)/CT imaging features of intra-abdominal desmoplastic DSRCT, and investigate the association of these features with histopathological results. The present study was a retrospective...

Primary ovarian lymphoma as the initial manifestation is rare. A 27-year-old woman presented to our hospital with the symptoms of lower abdominal fullness and pollakisuria. CT scan and MRI revealed bilateral ovarian tumors, which showed heterogeneous masses. 18F-FDG PET revealed strong uptake by the abdominal masses, and the maximum standardized uptake value (SUVmax) was 12.5. Abnormal uptake w...
