A ­case of menin­gio­ma with­in the cis­ter­na mag­na with­out ­dural attach­ment is report­ed. Meningiomas of the pos­te­ri­or fos­sa with­out ­dural attach­ment are ­very ­rare and ­have ­been clas­si­fied in to: 1) intra­ven­tric­u­lar menin­gio­mas; 2) menin­gio­mas of the ­tela cho­ri­oid­ea; 3) menin­gio­mas with­in the cis­ter­na mag­na. Only two cas­es of menin­gio­mas with­in the cis­ter­na mag­na with­out ­dural attach­ment ­have ­been report­ed, one in 1923 and ­another in 1938. The ­case now report­ed was stud­ied by angio­gra­phy and magnetic resonance and oper­at­ed ­with micro­sur­gi­cal tech­nique. We ­describe neu­ro­ra­dio­log­i­cal and oper­a­tive find­ings of ­this excep­tion­al menin­gio­ma with­in the cis­ter­na mag­na with­out ­dural attach­ment.
