The circulatory system connects the whole body and circulates blood to transport nutrients, blood cells, oxygen, hormones, and carbon dioxide. This mechanism makes it vulnerable to several infections. Similarly, the central nervous system communicates through the vascular system that it has an increased risk of infections. It is necessary to determine the source and type of infections so that it can be treated as early as possible.

A craniotomy was scheduled for excision of left-sided intracranial lesion. When Dr. Nelson reached the lesion, he noted an encapsulated mass filled with purulent material. He took two sets of cultures and proceeded to remove the capsule and purulent collection. He had the circulating nurse look back at the referring physician’s history and she read that the patient had two root canal procedures performed on the left upper side a few months ago. What type of lesion did Dr. Nelson find and remove? Is there a relationship between the patient’s history and the findings at surgery? In general, what other types of infections might cause the current intracranial findings? Do you think the patient has a good prognosis based on the pathological findings? Could the patient be at risk for a CNS infection because of the craniotomy procedure? Please answer questions 1,2,3,4, and 5 if possible.
