Case Reports
Sonographic and computed tomographic demonstration of hydatid cysts communicating with the biliary tree.
Hepatic hydatid disease is usually silent and discovered incidentally. Rupture of a hydatid cyst into the biliary tree is a serious complication and produces a clinical picture of biliary obstruction. We present the cases of 2 patients who had only nonspecific symptoms and laboratory test results indicative of biliary tract obstruction. ⋯ Both cases were surgically confirmed. Demonstration of the cyst and intrabiliary hydatid contents should form the basis for the diagnosis of a hydatid cyst's rupture into the biliary tree; detecting the point of communication further supports the diagnosis. An accurate preoperative diagnosis of this disease is essential for its prompt surgical management.

Case Reports
Sonographic detection of an isolated cuboid bone fracture not visualized on plain radiographs.
We report the case of an isolated cuboid bone fracture in a child that was missed on radiography but was diagnosed on sonography. Plain radiographs of the patient's right foot showed no fracture, whereas sonograms demonstrated a fracture of the cuboid bone that appeared as a steplike discontinuity in the cortical bone. The diagnosis was confirmed on MRI. ⋯ Other imaging modalities are usually advocated for diagnosing fractures that are missed by radiography. Over the last decade, sonography has been increasingly used for diagnosing occult fractures. Although its use in such cases is not yet fully established, we believe that in the future, the sonographic detection of an injury that corresponds to the site of the reported pain will be adequate for initiating treatment of many types of fractures.
