Traumatic atlantooccipital dislocation with survival.

Traumatic atlantooccipital dislocation is generally considered incompatible with life. However, there have been isolated survivals from this injury, and a few patients initially have minimal neurologic deficits disproportionate to the gravity of their injury, a feature that has not been adequately stressed. The potentially catastrophic results of delayed therapy make early radiographic detection imperative. Marked retropharyngeal soft-tissue swelling, an abnormal basion-odontoid alignment, and posterior displacement of the atlas are diagnostic of anterior atlantooccipital dislocation. In the more uncommon posterior atlantooccipital dislocation an abnormal basion-odontoid alignment associated with marked soft-tissue swelling should suggest the correct diagnosis. Conventional tomography can be confirmatory.

Pseudocyst formation in hereditary pancreatitis.

The previously estimated incidence of pseudocyst formation in hereditary pancreatitis is approximately 10%. Our experience in nine patients with hereditary pancreatitis yielded five surgically documented pseudocysts and three additional patients with radiographically documented mass effects. Recent studies have shown a 20% spontaneous regression rate for pancreatic pseudocysts (of all etiologies), when evaluated by B-mode ultrasonography; our experience suggests that the incidence of pseudocyst formation in hereditary pancreatitis is considerably higher than previously suspected. Ultrasonography is thought to be an excellent method for diagnosing this entity, of evaluating mass effects identified on radiographic studies, and of providing sequential evaluation of pseudocysts treated surgically or conservatively.

Barium enema as a diagnostic aid in children with abdominal pain.

Diagnostic barium enema is not a substitution for well executed physical examination, and its use should be reserved only for obscure situations. An abnormal roentgenogram provides valuable information, since the fear of missing acute appendicitis in these children is minimized. When normal, this diagnostic test may bring to early operation those with minimal symptoms or unusual presentations, thus avoiding the possibility of prolonged observation and perforation. In children with known associated severe medical maladies, diagnostic barium enema can serve to reaffirm the diagnosis prior to the hazardous operative intervention. It may also eliminate the need for operation in those conditions which mimic acute appendicitis. The use of diagnostic barium enema in the past three and a half years significantly improved our diagnostic capabilities in children with abdominal pain. There was a corresponding reduction in the number of normal appendixes removed. The efficancy and, above all, the safety of this procedure make it a valuable diagnostic aid in the care of children.

Film screening by physician assistants in diagnostic radiology.

Data are presented which indicate that specially selected ART students can be trained to evaluate radiographs as to the presence or absence of significant pathology with an accuracy equivalent to that of experienced staff radiologists. The methods employed in this training program-namely, stressing perceptual recognition of normal and abnormal findings-may be beneficial in the early months of training of diagnostic radiology residents to hasten achievement of an acceptable perceptual performance. Test films, used in this study as an evaluation technique, may also be useful to assess residents' progress.

Massive enlargement of the ileocecal valve due to lymphoid hyperplasia.

Two children with unusual infiltration of the ileocecal valve by lymphoid tissue are described. The large filling defect identified on barium enema may suggest a number of conditions. Operative resection will exclude the possibility of a malignant process and will reduce the chance of recurrent intussusception.

Radiologic aids in the diagnosis of appendicitis in children.

Chest and abdominal radiograms are most helpful in evaluating acute abdominal pain in children. When basilar pneumonia is found the likelihood of associated appendicitis is slim. Evidence of appendicolithiasis on abdominal films secures the diagnosis of acute appendicitis and should prompt the surgeon to early operative intervention, since the threat of appendiceal perforation is great. Barium enema is safe and informative when obscure clinical presentation or associated illness exists. The likelihood of appendicitis is great when the appendix fails to fill at the time of barium enema. Complete filling of the appendix excludes the possibility of acute appendicitis.
