“…Infact several authors have reported on subarachnoid haemorrhage during transphenoidal surgery for pituitary adenomas, due to accidental damage to previously undetected intracranial aneurysms [ 15 – 17 ]. Some authors recommend routine preoperative carotid artery angiography in all patients with pituitary macroadenomas before trans-sphenoidal surgery [ 18 ].…”

BackgroundPituitary dysfunction in adults are often associated with tumors of the gland and manifests with mass effects and hypopituitarism. MRI of pituitary region often provides confirmation of the diagnosis and assists in planning neurosurgery.Case presentationA 69 years old female evaluated for chronic headache was found to have a supra-sellar mass lesion that mimicked a pituitary tumor, with biochemical evidence of hypopituitarism. Cerebral angiogram confirmed the diagnosis of an aneurysm of the intracavernous internal carotid artery. She was successfully treated with coil embolization of the aneurysm and achieved resolution of symptoms and return of biochemistries to normal.ConclusionCarotid aneurysm can mimc pituitary tumours clinically and radiologically on MRI scan. This rare possibility should be considered in evaluating supra-sellar masses to avoid catastrophic consequences.

“…Unii autori preferă rezolvarea acestora în două etape pe când alții într-o etapă. De preferință este a doua, pentru a reduce maximal posibil complicațiile legate de intervenții, durata spitalizării, dar evident cu analiza minuțioasă a particularităților patologiei pacientului [6,7]. Accesul pterional clasic este unul din cel mai recomandat, care oferă cel mai bun rezultat posto-Figura1.…”

The association between cerebral sacral aneurysm and pituitary adenoma has not yet been well elucidated, with some authors reporting an incidence of up to 7.4%. The cause is not yet fully known. 97% of these aneurysms belong to the anterior cerebral circulation. Description of a case study in which a functional selective expansive process and uninterrupted intracerebral aneurysm of the middle cerebral artery are determined. The 57-year-old patient is diagnosed with 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 patient underwent micro-neurosurgery to ablate the saddle formation and the concomitant clipping of the cerebral aneurysm by a classical 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 complications with subsequent adjuvant treatment. The association of these two pathologies is extremely rare. The literature describes the solution of these two pathologies in a single intervention, without essential post-operative complications, as described in the case presented.

“…If the AComA is involved in vascular anomalies such as cerebral aneurysms, AComA descent might result in vascular complications during or after TSS, which are life-threatening consequences. [ 1 3 5 6 9 11 12 13 ] Vascular complications during and after TSS are the result of abrupt tumor capsule collapse into the sella turcica following adenoma removal, which may cause traction of the AComA.

Background:After removal of pituitary macroadenoma, the anterior communicating artery (AComA) descends toward the original position. However, the process and contributing factors of this descent are not elucidated.Methods:This retrospective study included 102 patients who underwent transsphenoidal surgery (TSS) for macroadenomas with maximum diameters of >2 cm. Sequential T2-weighted magnetic resonance images were used to assess the AComA flow void and its distance from the planum sphenoidale before and after TSS. The AComA position in relation to the adenoma was divided into four groups as follows: anterior, anterosuperior, superior, and posterior. The descent was compared to the presence of intratumoral hemorrhage or adenoma extension into the sphenoid sinus.Results:One week after TSS, the AComA descent was more pronounced than when originally in the superior position (6.5 ± 3.7 mm vs 4.4 ± 3.5 mm, P < 0.0001). The postoperative descents of the AComA were well correlated with those of residual adenomas only when in the superior position (P = 0.030). The AComA descent was more significant at 1 week (4.4 ± 3.5 mm) than at 1 week to 3 months (0.7 ± 1.0 mm) in all the groups. Both intratumoral hemorrhage and sphenoid sinus extension of adenoma did not affect the AComA descent in each group.Conclusion:AComA descent was most influenced when it was superior to the macroadenoma and progressed mostly within 1 week after TSS, probably initiating during TSS. The position of the AComA in relation to a macroadenoma should be considered preoperatively to avoid vascular injury.
