Acute cholecystitis is a common cause of the acute abdomen. The diagnosis has been distinctly improved with the development of ultrasonography and hepatobiliary scanning over the past 20 years. The treatment is cholecystectomy, with early as opposed to delayed operation gaining increasing popularity nationwide. Acute acalculous cholecystitis and emphysematous cholecystitis are special features of acute cholecystitis occurring in more complicated cases and requiring diligence in diagnosis and great care in treatment.

We describe herein the unusual case of a 68-year-old Japanese man who underwent laparotomy for an acute abdomen caused by diffuse peritonitis, which revealed perforation of the gallbladder without any stones. A cholecystectomy was subsequently carried out, and histological examination showed marked atherosclerosis of the gallbladder associated with acute inflammatory changes. It is most likely that circulatory disturbance of the gallbladder wall due to the atherosclerosis played an important role in the events leading to perforation. Acute acalculous cholecystitis is an uncommon condition which is extremely difficult to diagnose preoperatively. The clinicopathological features of this patient are of particular interest and importance in terms of pathogenesis as well as treatment.

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.
