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...

STUDY DESIGN A variety of interbody implants were imaged by computed tomography and plain radiography within cadaveric spines to evaluate their basic imaging characteristics. OBJECTIVES Sources of interpretation error by both computed tomography and plain radiography of interbody implants were investigated. SUMMARY OF BACKGROUND DATA Lucencies have been reported around bone dowel implants i...

STUDY DESIGN Prospective study. PURPOSE The main purpose of this study was to clarify the range of magnification errors on digital plain radiographs and to determine if there is a correlation between the body mass index (BMI) of a patient and the magnification error. OVERVIEW OF LITERATURE Most clinicians currently use digital plain radiography. This new method allows one to access images a...

A 45-day-old male infant presented with signs of acute intestinal obstruction for two days. Abdominal examination revealed a mass in the right lower abdomen. Ultrasound showed a cystic mass measuring 4x3 cm, in the right lower quadrant at the level of lower pole of right kidney. The plain abdominal radiograph showed haziness in the middle and lower third with bowel loops pushed to upper third o...

A case of a 63-year-old man with small bowel ischemia six weeks after transplantation surgery is presented. Plain abdominal radiograph obtained several days after ingestion of barium shows the sign of prolonged barium coating indicating severe mucosal damage. Abdominal CT scan demonstrates small bowel wall thickening as well as pockets of peritoneal fluid collections. Most critically, CT allows...

Neonatal acute gastric volvulus is rare and often associated with diaphragmatic anomalies. Patients usually present with vomiting and respiratory distress, but excessive salivation, failure to pass a nasogastric tube beyond 20 cms and the presence of a space occupying thoracic lesion should also prompt a search for the entity. The authors describe a case presenting with these atypical findings ...

Osteoblastoma is a rare benign tumor of the calvarium. We present the case of a 20-year-old female with occipital osteoblastoma and discussion of imaging modalities of calvarial osteoblastoma. To our knowledge, this is the ninth reported case of occipital osteoblastoma. Imaging characterization of osteoblastoma may vary. Plain radiograph, CT, MRI, and CT angiography establish osteoblastoma char...

Foreign bodies in lower urinary tract may present in a different number of ways. We report four cases of such unusual presentation. Physical examination and plain radiograph was sufficient enough to confirm our diagnosis in all cases. The cases belonged to different age groups and three out of four cases were managed by open surgical approach. One foreign body was removed using cystoscope. Prom...
