The purpose of this article is to review imaging findings and to discuss the optimal imaging methods for craniosynostosis. The discussion of imaging findings are focused on ultrasonography, plain radiography, magnetic resonance imaging and computed tomography with 3-dimensional reconstruction. We suggest a strategy for imaging work-up for the diagnosis, treatment planning and follow-up to minim...

The reported incidence of lumbar pedicle screw malpositioning is between 5 and 40%. Post-operative neural deficits related to screw misplacement have been reported at rates between 3 and 11%. Radiography alone is an unreliable tool for determining pedicle wall violation due to malpositioned screws, whether by intra-operative fluoroscopy, plain X-ray, imageguided surgery systems based on radiogr...

Superior dislocation of the patella with intact patellar tendon is a rare condition. Most cases in literatures were diagnosed by clinical examination and plain radiography; however there are many cases that were misdiagnosed as patellar tendon rupture. In this case, we demonstrate the use of ultrasound for diagnosis of superior dislocation of the patella in the emergency department. We also inc...

We present the case of a child with abdominal cramping found to have radiopaque matter in his gastrointestinal tract on plain radiography. The parents denied ingestion of a foreign substance but specific questioning revealed a visit for dental care the previous day. This may serve to illustrate the benefits of taking a careful goal-directed history as opposed to the often recommended open-ended...

Kienböck disease is a condition characterized by avascular necrosis of the lunate bone. Advanced imaging can aid in the diagnosis and staging of Kienböck disease. Magnetic resonance imaging (MRI) is an important adjunct to diagnosis. In particular, MRI is helpful early in the disease when plain radiographs may not reveal abnormalities. A 17-year-old man with Kienböck disease who underwent radio...

Limy bile is a relatively rare condition, in which a radiopaque material is visible in the gallbladder on plain radiography or computerized tomography. Cases of complicated hyperparathyroidism are extremely rare. We report a patient with right upper quadrant and epigastric pain and extremity weakness in whom abdominal tomography showed limy bile in the gallbladder and laboratory values showed h...

In the past, dental disease and lesions involving the jaw were either evaluated by plain radiography or tomography. The advent of spiral computed tomography (CT) and DentaScan is changing the imaging trend. It is now not only used for pre-implant assessment but also in the diagnosis of lesions affecting the jaw. This pictorial review discusses the role of DentaScan in the various abnormalities ...

A 48-year-old diabetic woman presented to the United Christian Hospital with fever of acute onset and right loin pain. Physical examination revealed tenderness with a ballotable right kidney. Clinically, the patient was septic with blood pressure on the low side. Laboratory data revealed leukocytosis with a left shift and an elevated creatinine level. A plain kidney, ureter, and bladder (KUB) r...

Chondroid lipoma is a rare and unusual benign soft tissue lesion. Although there have been several reports of the imaging findings of chondroid lipoma, very few described the radiographic calcification or ossification in a chondroid lipoma. We present a case of chondroid lipoma with adipose tissue and ossified components on plain radiography and MRI images. Correlation of imaging findings and p...
