The sonographic features of neonatal appendicitis: A case report.

ABSTRACT

RATIONALE Neonatal appendicitis is extremely rare, and preoperative diagnosis is challenging. This study aimed to investigate the utility of ultrasound for the diagnosis of neonatal appendicitis. PATIENT CONCERNS Four cases of neonatal appendicitis were included in this case series. One was a female infant and the other 3 were male infants; they were aged from 10 to 17 days. DIAGNOSES Neonatal appendicitis. INTERVENTIONS: Four newborns in our hospital were diagnosed with neonatal appendicitis by abdominal ultrasound. Their sonographic features were summarized and compared with surgical and pathological findings. OUTCOMES: In these infants, abdominal ultrasound demonstrated ileocecal bowel dilatation, intestinal and bowel wall thickening, and localized encapsulated effusion in the right lower quadrant and the abscess area, which was assumed to surround the appendix. LESSONS Ultrasound is helpful for the diagnosis of neonatal appendicitis.
