Subarachnoid Cisternal Craniopharyngioma (Type “S”)

Pp. 201-215 (15)

In this chapter, we focus on a subgroup of craniopharyngioma (CP) in which the main tumor body is located exclusively in the suprasellar subarachnoid cisternal space around the pituitary stalk (PS) and there is no third ventricle involvement. Notably, the cases of CP reported in this chapter were not clearly defined in previous literature. The main reason for the confusion regarding this type of CP might be the lack of uniform criteria for evaluating the relationship between the tumor and third ventricle walls. The terminology “suprasellar extraventricular CP,” which is used in previous literature, might be another term for the cases described in this chapter; however, this term does not truly reflect the tumor origin and location.
