Computed tomography of choanal atresia: special considerations of the unilateral type.

Seven cases of choanal atresia are presented: four cases with bilateral choanal atresia, and three cases with unilateral choanal atresia. The patients in three of these cases were born with the CHARGE association--an association of choanal atresia with coloboma, heart disease, retarded growth, genital hypoplasia, and ear anomalies. Diagnosis in all cases was confirmed. Computed tomography generally confirms the clinical diagnosis of bilateral choanal atresia. Unilateral choanal atresia, however, presents late, and both the clinical and radiographic manifestations may be subtle. In all our cases of unilateral choanal atresia, computed tomography demonstrated the definitive components accounting for this deformity. Computed tomography, because it so accurately defines the anatomic malformation, is now the imaging modality of choice in this entity.

Neonatal colonic atresia: ultrasound findings.

High resolution real-time ultrasound examination of the abdomen was performed in a neonate with abdominal distention. Dilated distal small bowel and a complex mass in the course of the ascending colon were noted. Ultrasound correctly suggested the diagnosis of mid-colonic atresia with a patent ascending colon twelve hours prior to the radiographic demonstration of gas in the obstructed right colon. The sonogram was also able to accurately exclude the presence of ascites or a renal or hepatic mass as the cause for abdominal distention.

Bronchial rupture in children following blunt chest trauma. Report of five cases with emphasis on radiologic findings.

We present five patients with fracture of the bronchus, in whom the diagnosis of bronchial rupture was first suggested because of persistent leakage of air, atelectasis of a segment of the lung or of the entire lung, mediastinal and deep cervical emphysema. In all patients the bronchoscopy was essential to confirm the diagnosis and to determine the full extent of injury.

Osgood-Schlatter's disease, an emphasis on soft tissue changes in roentgen diagnosis.

Osgood-Schlatter's disease is a well known entity affecting the adolescent knee. Radiologic examination of the knee has been an integral part of the diagnosis of this condition for decades. However, the soft tissue changes have not been appreciated sufficiently. Emphasis is placed on the use of optimum radiographic technique and xeroradiography in the examination of the soft tissues of the knee.
