RESUMO
The early occurrence of peritoneal signs and hyperamylasemia in a 14-year-old boy, who had fallen off his horse, urged us to perform a sonographic and computed tomographic study of the upper abdomen. Both examinations showed a complete pancreatic rupture. Distal pancreatectomy led to a rapid and uneventful recovery.

Three infants with nonobstructive bile duct dilatation (Caroli disease) are described. The bile duct pathology was associated with autosomal recessive polycystic kidney disease in two patients and with severe destruction of the renal parenchyma of unknown origin in the other. Sonograms of the liver showed, besides bile duct dilatations, intraluminal bulbar protrusions, bridge formation across dilated lumina, and portal radicles partially or completely surrounded by dilated bile ducts. Liver biopsy was performed in two patients, and in one patient, the biopsy sample confirmed the findings noted on sonograms. These findings support the hypothesis that the normal embryogenesis of intrahepatic bile ducts is arrested in the pathogenesis of this disease.

"Skip areas" in focal steatosis describes a newly proposed "subsegmental type" of focal steatosis, which differs in both extent and topography from the more classic "lobar or segmental type" of focal steatosis. In the subsegmental type of steatosis, fatty infiltration can be considered homogeneous throughout the liver, with the exception of small flattened portions of less affected parenchyma, called "skip areas." These regions are mainly located in the subcapsular areas or along the interlobar fissures or the gallbladder bed. Observations using ultrasound in vivo, as well as on postmortem in vitro angiograms, suggest that both the extent and topography of these skip areas can be explained by local differences in vascular anatomy.

A typical case of thinning of the parietal bones in an elderly female patient is reported. Frontal CT sections adequately demonstrate the disappearance of the diploë and the flattening of the outer table.
