Acute cholecystitis in the neonate is rare and usually treated by cholecyst
ectomy. A 1-day-old full-term girl had clinical and sonographic features of
acute calculous cholecystitis. This was successfully managed nonoperativel
y with intravenous fluids and antibiotics, leading to complete resolution o
f the condition. The infant currently is thriving and asymptomatic with a s
onographically normal biliary tree. Spontaneous resolution of cholelithiasi
s may occur in neonates, even in the presence of acute cholecystitis. J Ped
