[Primary acute acalculous cholecystitis in childhood: a report of 2 clinical cases].

Acute acalculous cholecystitis (AAC) is not frequently encountered in adults and children whether in association with other conditions or above all in primitive form. AAC in infancy, although rare, is well recognized, but its possible presentation is not always kept in mind in considering the differential diagnosis of the acute abdomen. On the other hand, AAC has significant clinical signs and abdominal u.s. scanning usually provides evidence of diagnosis. Only early diagnosis has been shown to limit high morbidity and mortality rates for AAC, since cholecystectomy is the simple procedure of choice for treatment of AAC. We report two cases of primitive AAC one in a six and one in two half years old girls. So we consider the most important features about etiologic factors, pathogenesis, clinical signs and therapy through review of the literature and our personal experience.
