Vertebral Aneurysmal Bone Cyst Mimicking Osteosarcoma: Case Report and Review of the Literature.

Aneurysmal bone cysts are benign osseous lesions containing blood-filled cavities separated by walls of connective tissue. They can be difficult to identify clinically due to similarities in presentation, imaging, and histology with other pathologies. Specifically, it is important to distinguish these benign lesions from malignant processes, as both surgical and medical management differ.

Sudden Death Associated With Incarcerated Small Bowel Due to Mesodiverticular Band.

Meckel's diverticulum is a congenital anomaly present in about 3% of the population and usually asymptomatic. Rarely, a mesodiverticular band extends from the tip of a Meckel's diverticulum to the mesentery, thought to be due to lack of involution of the left vitelline artery. The presence of this band creates a closed loop through which loops of bowel can become entrapped.
