Periportal tracking in pediatric blunt abdominal trauma. Correlation with liver enzymes and liver injury.

This is a retrospective study of the computed tomography (CT) examinations and medical records of 243 consecutive pediatric patients sent for CT studies after blunt abdominal trauma. The purpose of the study was to determine the frequency and significance of periportal tracking identified by CT, and correlate this finding with liver enzyme levels and liver injury. Periportal tracking (PPT) was divided into four grades (0-3) depending upon the distribution of decreased attenuation adjacent to the portal vessels. Circumferential PPT extending to the periphery of the liver (grade 3) was found in 20/243 children. They had a higher incidence of liver parenchymal injury seen on CT 20% versus 0.5% in combined PPT grades 0-2. Sixteen children with grade 3 PPT and no liver injury had significantly elevated liver enzymes as compared to children with combined 0-2 grade PPT. Eleven of the 20 children with grade 3 PPT had no other CT evidence of intraabdominal injury and none of these patients developed intraabdominal hemorrhage. Thus, grade 3 periportal tracking as an isolated abnormality did not indicate a clinically significant liver injury in any patient.

Imaging of primary rhabdomyosarcoma of the diaphragm.

This is a report on a rare case of embryonal rhabdomyosarcoma involving the diaphragm in a 3-year-old boy. This case illustrates the importance of preoperative imaging in the management of this tumor.

Neonatal hepatic abscess.

Neonatal liver abscess is a rare entity. There are no published reports of neonatal liver abscess in the radiology literature in the past 15 years. We recently encountered a premature infant in whom a hepatic abscess was diagnosed solely based on abnormal radiographic studies. We report this case to illustrate the unusual clinical and radiographic abnormalities seen with neonatal solitary hepatic abscess.

Imaging of an unusual case of parasitic twinning.

Conjoined twins are rare in the literature and parasitic conjoined twins are rarer still. To our knowledge no cases of parasitic conjoined twins have previously been reported in the radiology literature. We present a case of parasitic conjoined twins in which radiographic findings played an important role in management.

Cranial sonography of the occipital horns and gyral patterns in the occipital lobes.

Cranial sonographic examinations of 199 neonates were evaluated to determine the incidence of an echogenic pattern in the occipital lobe that simulated a mass, to relate that finding to the birth weight, and to correlate it with the gyral development of the occipital lobe. This echogenic pattern was seen in infants weighing less than 1750 g at birth and was identified on both sides of the midline on the most medial paramedian sagittal sonogram scans of the head. This pseudomass was found to be due to close approximation of a large occipital horn and calcarine fissure joining other adjacent secondary fissures. The multiple fissures formed an echogenic star, and the proximity of the occipital horn and premature brain tissue texture contributed to the relatively hypoechoic background of the pseudomass. The pseudomass is limited superiorly by the parietooccipital fissure and inferiorly by the tentorium. This sonographic pattern should be recognized as a normal variant.
