Radiologic features of hydatid disease: the importance of sonography.

Hydatid disease is commonly encountered in specific geographic areas of the world. Hydatidosis affects multiple organs and has diverse radiologic presentations. Sonography remains an important modality for diagnosing this condition, as it optimally detects cystic structures, floating membranes, and debris.

Complete large bowel duplication with paraduodenal cyst: prenatal sonographic features.

Objectives: To illustrate diagnostic dilemmas while considering a diagnosis of complete large bowel duplication and duodenal duplication cysts.

Methods: A case of large bowel dilatation with a peripancreatic cyst was identified sonographically in a 27-year-old gravida 3 at 35 weeks of gestation, suffering from gestational diabetes and pregnancy-induced hypertension.

Results: On the basis of sonographic findings of dilated, hyperperistaltic large bowel loops, and a large cyst with echo-free contents near the pancreas, a diagnosis of large bowel obstruction with a paraduodenal cyst was considered.
