Umbilical cord cysts: evaluation with different 3-dimensional sonographic modes.

Objective. The purpose of this series was to determine whether the use of different 3-dimensional (3D) sonographic modes allows better definition of umbilical cord cysts and pseudocysts in utero. Methods. Two cases of umbilical cord cysts and 1 of a pseudocyst were analyzed and compared with 2-dimensional (2D), 3D, angiopower Doppler, tomographic ultrasound imaging (TUI), virtual organ computer-aided analysis (VOCAL), and automatic volume calculation (AVC) sonographic modes. All cases were followed during pregnancy. A karyotype analysis was also obtained. Results. Three-dimensional sonography, TUI, and VOCAL allowed clear visualization and evaluation of the sizes, locations, and numbers of …
