Background Subocclusive intestinal syndrome is caused by a heterogeneous group of enteric neuromuscular diseases that causes abnormalities of gut motility. Subocclusive syndrome can occur at any age, but in young children, most often, can be fatal. This may be due to intrinsic primary or secondary visceral disorders (drug toxicity, ischemia, inflammatory or autoimmune diseases, infection with Epstein-Barr virus or cytomegalovirus, myopathies).

Case presentation We present the case of an infant male, 1 month and 2 week old, admitted in the Paediatric Gastroenterology Clinic, „St. Mary’ Children Emergency Hospital, Iasi, Romania for jaundice and the appearance of flatulence, with progressive intensification from the age of 3 week old, with loose stools. Laboratory analysis revealed a positive Cytomegalovirus IgG and IgM antibodies.

Conclusion Cytomegalovirus infection should be considered in intestinal pseudo-obstruction in order to initiate appropriate treatment and avoid serious complications that may arise.
