FUNCTIONAL PITUITARY ADENOMA ASSOCIATED WITH NON-RUPTURED ANEURYSM OF THE MIDDLE CEREBRAL ARTERY. CASE STUDY

Abstract

The association between cerebral sacral aneurysm and pituitary adenoma has not yet been well elucidated, withsome authors reporting an incidence of up to 7.4%. The cause is not yet fully known. 97% of these aneurysms belongto the anterior cerebral circulation. Description of a case study in which a functional selective expansive process anduninterrupted intracerebral aneurysm of the middle cerebral artery are determined. The 57-year-old patient is diagnosedwith pituitary adenoma with cavernous sinus invasion and Cushing’s syndrome. On investigation by MRI and AngioCT,an associated aneurysm of the right cerebral artery on the right, uninterrupted, is incidentally determined. The patientunderwent micro-neurosurgery to ablate the saddle formation and the concomitant clipping of the cerebral aneurysm by aclassical right approach. After the operation, a partial ablation of the intracavernous adenoma and a definitive clipping of the aneurysm were achieved. The patient is discharged from the institution after 5 days, without additional complicationswith subsequent adjuvant treatment. The association of these two pathologies is extremely rare. The literature describesthe solution of these two pathologies in a single intervention, without essential post-operative complications, as describedin the case presented.
