[Coronary angiography with multislice computed tomography].

Echocardiography allows visualization of the origin of the coronary arteries and their proximal trajectory but evaluation of the middle and distal portions of these vessels is limited. Invasive coronary angiography is currently the procedure of choice to evaluate coronary anatomy. New imaging techniques have recently been developed that allow coronary structures to be visualized. One of these techniques is multislice or multidetector computed tomography (MSCT) which provides a static image of the final distribution of contrast in the vascular tree. We report a patient in whom a differential diagnosis between myopericarditis and myocardial ischemia was being considered. MSCT coronary angiography allowed the coronary tree to be visualized and anomalies in this location to be ruled out. The main limitations of MSCT coronary angiography in children are elevated cardiac frequency, making high quality images difficult to obtain, and irradiation. Although the use of MSCT coronary angiography to evaluate coronary arteries in the pediatric population currently presents considerable limitations, this procedure can be useful in selected children with suspected congenital anomalies, aneurysms or coronary fistulas who are not considered suitable candidates for conventional invasive coronary angiography.

[Non-dystonic torticollis. A report of a case secondary to retropharyngeal abscess].

INTRODUCTION: There are many causes of acquired non-dystonic torticollis: cervical bony anomalies, nasopharyngeal infections, tumours of the spinal cord, and posterior fossa, ocular, vestibular and gastrointestinal disorders. In children, non-dystonic is commoner than dystonic torticollis, except for in adverse reactions to drugs. Palatopharyngeal lesions due to a rigid object being impacted in the mouth (pencil-injury) are common in childhood. Many are not dangerous and require no specific treatment, although there is a risk of perforation of the pharyngeal wall and of a retropharyngeal abscess. CLINICAL CASE: We report the case of a 9 year old boy who was seen in the Emergency Department complaining of fever present for four days and progressive cervical rigidity for the past two days which did not improve with myorelaxant drugs. A lateral X-ray of the spine showed prevertebral air and on the oesophagogram a fistula tract was seen. On further questioning the boy admitted that a stick he had had in his mouth had caused damage the day before his fever started. CT showed the extent of the abscess. After a week of treatment with antibiotics and corticosteroids the clinical features disappeared, and on CT after two weeks it was seen that the abscess had resolved. CONCLUSIONS: We suggest that a lateral radiograph of the neck should be done in cases of acquired torticollis, even though there is no suspicious clinical history. Early diagnosis and treatment of retropharyngeal abscesses is essential to prevent extension to adjacent structures, and atlanto-axoid subluxation secondary to the oedema and tension of the ligaments caused by the abscess (Grisel's syndrome).
