Intrasellar aneurysm and a growth hormone—secreting pituitary macroadenoma
Bibliographic record
Abstract
An aneurysm completely included within a pituitary adenoma that lies inside the sella turcica is rare and challenging from both a diagnostic and treatment viewpoint. A 39-year-old woman presented with symptoms and signs of acromegaly. Magnetic resonance imaging revealed a pituitary macroadenoma, which was associated with an intrasellar aneurysm. Digital subtraction angiography confirmed the presence of the cavernous carotid artery aneurysm. Complete endovascular obliteration of the aneurysm was achieved using Guglielmi Detachable Coils and the patency of the internal carotid artery was maintained. The pituitary adenoma was resected subtotally via a transsphenoidal microsurgical approach 8 months later. Preoperative detection of a coexisting intrasellar aneurysm in a patient with a pituitary adenoma is mandatory to avoid life-threatening hemorrhagic complications. Endovascular coil placement is an effective treatment option when performed before the transsphenoidal removal of the adenoma.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
