SUPRASELLAR ANEURYSM

We wish to report a case of suprasellar aneurysm exposed and incised at operation. A large muscle graft was packed into the aneurysmal sac. This is the sixth instance that we have found of a patient's surviving the opening of a suprasellar aneurysm. Since we have been able to find but few cases of this type in the literature, we wish to emphasize certain aspects of the problem of suprasellar aneurysm both from the diagnostic and from the therapeutic standpoint.

Dandy 1 has reported several such cases of pure arterial aneurysm diagnosed by clinical means and cured by operation. A second type of aneurysm has been but little mentioned in the literature.
