Diffuse Non-obstructive Bowel Dilatation in utero: Report of a Case with a Unique Presentation.
The Tokai journal of experimental and clinical medicine(2021)
Abstract
Thus far, few reports have described the rare, non-obstructive type of fetal diffuse bowel dilatation. We describe such a case in the fetus of a 31-year-old Pakistani pregnant woman, gravida 3, para 2. A series of ultrasonographic examinations in the third trimester showed a "honeycomb" appearance of fetal d iffuse dilated bowel loops, a mildly enlarged stomach, and mild polyhydramnios. Magnetic resonance imaging further revealed fluid-filled dilated bowel loops extending to the colon and rectum. The male neonate was born at 36 weeks and had marked abdominal distension but did not show signs of mechanical bowel obstruction. He passed a profuse amount of liquid with meconium at 4 h of life. Thereafter, his distended abdomen and bowel dilatation subsided, and he became asymptomatic within a week of life. Taken together with previous case reports, among infants who show the "honeycomb" sign in utero, there definitely exists a subset with a favorable outcome and an unknown etiology. This case alerts physicians who are responsible for perinatal care to the fact that careful assessment is required for a newborn when the "honeycomb" sign is observed via fetal imaging. Without evidence of mechanical bowel obstruction, alternative etiologies should be sought to avoid unnecessary laparotomy.
