Neonatal adenomyomatosis of the gallbladder: An incidental finding at 12 hours of life

Abstract

Adenomyomatosis of the gallbladder, although relatively common in adults, is a rare entity in the pediatric age group. Controversy still exists as to whether or not to perform followup ultrasound, as there is a questionable increased risk of gallbladder carcinoma in adults. We present a case of neonatal adenomyomatosis that was diagnosed at 12 hours of life in a term newborn.

Adenomyomatosis of the gallbladder in an adolescent, a very rare condition

“…5,8 In two asymptomatic patients diagnosis was made incidentally by ultrasound imaging, one with Beckwith-Wiedemann syndrome, 2 and the other was a neonate. 12 In our patient the symptoms were highly unspecific. Despite the fact that most children in this series were symptomatic, according to Akcam 1 most patients with ADMG might not be diagnosed before adulthood because it shows no symptoms before the development of stones or inflammation.…”

“…5,8 En dos pacientes asintomáticos, el diagnóstico se hizo por casualidad durante una ecografía; uno tenía síndrome de Beckwith-Wiedemann 2 y el otro era un recién nacido. 12 En nuestro paciente, los síntomas eran sumamente inespecíficos. A pesar de que la mayoría de los niños en esta serie tenían síntomas, según Akçam, 1 la mayoría de los pacientes con adenomiomatosis vesicular podrían no recibir el diagnóstico antes de la adultez debido a su naturaleza asintomática antes del desarrollo de cálculos biliares o inflamación.…”

Adenomyomatosis of the Gallbladder as a Cause of Recurrent Abdominal Pain

“…Adenomyomatosis of the gallbladder is a benign, degenerative condition characterized by localized, segmental, or diffuse epithelial proliferation and subsequent deep invagination of the mucosa within the hypertrophied muscular layer of the gallbladder. [3][4][5][6][7][8] The prevalence in children is unknown. 4,5 The pathogenesis of adenomyomatosis of the gallbladder is unclear; abnormal neurogenic function and muscular contraction of the gallbladder may induce glandular proliferation and hyperplasia of the smooth muscle.…”
