Association of an intracranial arteriovenous malformation and a meningioma

Abstract A case of a simultaneously discovered arteriovenous malformation (AVM) and a meningioma is presented. A review of the literature revealed only four similar cases, but there have been 30 reports of other intracranial tumors in association with AVM. The possible mechanisms of this rare association are discussed.

Cholelithoptysis: An unusual complication of laparoscopic cholecystectomy

Laparoscopic cholecystectomy is emerging as a preferred surgical method in the treatment of cholecystitis. Decreased morbidity and mortality rates make this an attractive alternative to conventional cholecystectomy. Recently, specific complications including bile duct transection, biloma formation, and liver lacerations have been reported. We report here, however, an unusual case of intraoperative spillage of stones into the intraperitoneal cavity. Subsequent erosion through the diaphragm resulted in expectoration of stones, or cholelithoptysis.
