Postprocedure sepsis in imaging-guided percutaneous hepatic abscess drainage: how often does it occur?

Objective: This retrospective study was conducted to determine the incidence of sepsis at our institution after percutaneous drainage of a hepatic abscess.

Materials And Methods: Thirty-three patients with a hepatic abscess treated using percutaneous aspiration and drainage from 1995 to 2000 were identified from a search of the interventional database. The patients' charts and CT images were reviewed independently by two radiologists for clinical presentation, relevant medical history, pre- and postprocedure antibiotic regimens, and clinical course after percutaneous aspiration and drainage.

Sonography of fetal choroid plexus cysts: detection depends on cyst size and gestational age.

Objective: To establish diagnostic criteria for the diagnosis of fetal choroid plexus cysts across gestation.

Methods: Prenatal sonographic images of 166 fetuses without choroid plexus cysts were prospectively collected from 13 weeks to term. Texture characteristics of the choroid plexus regions were analyzed to quantify changes as a function of gestational age.
