Acute mesenteric ischaemia: a rare complication mimicking necrotising enterocolitis in a premature infant

Acute mesenteric ischaemia (AMI) is a life-threatening gastrointestinal complication uncommonly described in premature infants. The diagnosis of AMI is challenging and may be delayed due to the limitation of accurate diagnostic imaging and non-specific clinical signs. Furthermore, AMI can be misdiagnosed as necrotising enterocolitis (NEC) due to the overlapping clinical and radiological features. Though known to be associated with high mortality rates, early recognition and intervention can improve the survival rates in infants with AMI. We describe a case of a premature infant who presented with an acute abdomen and haemodynamic collapse, initially treated for NEC but later diagnosed with AMI intraoperatively. Due to the extensive bowel necrosis, surgical intervention was rendered futile and the infant finally succumbed to the disease.
