Abstract
The cranial base could be divided anatomically into anterior, middle, and posterior cranial fossae. Skull base lesions refer to pathologies that develop within the cranial base bone itself, or those that involve structures on either side of the skull base bones, with a wide diversity of tissues. Therefore, a variation of pathologies can arise in these areas. This could also include both benign as well as malignant lesions.Patients with skull base lesions could be asymptomatic, with their lesions discovered incidentally while performing imaging for other purposes. This is usually the case when these lesions are relatively in an early stage. This by itself sometimes poses difficulty in the decision making process of whether or not to operate on these asymptomatic patients, given the potential morbidity from the surgical intervention itself. In contrast, patients become symptomatic whenever their lesions are in advanced stages. Imaging, primarily CT and MRI scanning, is critical for preoperative assessment
