Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Clinical Presentation
Classic features (may be incomplete)
- Sudden severe headache (most common)
- Visual disturbance (chiasmal compression)
- Ophthalmoplegia (CN III, IV, VI)
- Nausea/vomiting
- Altered consciousness
- Signs of adrenal insufficiency
- History of known pituitary adenoma (50%)
03Warning IMMEDIATE Hydrocortisone
Give BEFORE imaging if apoplexy suspected
- Hydrocortisone 100mg IV bolus STAT
- Then 50-100mg IV q6h OR 2-4mg/h infusion
- Do NOT wait for cortisol results
- Adrenal crisis can be fatal
- Most patients have hypopituitarism
04Action Urgent MRI Pituitary
MRI is imaging of choice
- MRI: hemorrhage (T1 hyperintense)
- Demonstrates tumor extent
- Shows chiasmal compression
- Cavernous sinus involvement
- CT if MRI unavailable (less sensitive)
- MRA/CTA to rule out aneurysm if uncertain
05Action Formal Visual Assessment
Document baseline - URGENT ophthalmology
- Visual acuity (each eye)
- Visual field testing (confrontation/formal)
- Pupillary responses
- Eye movements (III, IV, VI)
- Fundoscopy (optic disc)
- Document time of assessment
06Action Pituitary Apoplexy Score (PAS)
UK Guidelines - guides management
- GCS: 15 (0), 8-14 (2), <8 (4)
- Visual acuity: Normal (0), Reduced (1), CF/HM/LP/NLP (2)
- Visual field: Normal (0), Defect (1), Severe/Hemianopia (2)
- Ocular paresis: None (0), Unilateral (1), Bilateral (2)
- Score <4: Conservative may be appropriate
- Score ≥4: Consider surgery
07Decision Surgical Indications?
Based on PAS and clinical status
08Warning Surgical Indications Present
Transsphenoidal surgery recommended
- Reduced visual acuity
- Severe/progressive visual field defect
- Deteriorating level of consciousness
- PAS ≥4
- No improvement or deterioration on steroids
09Action Transsphenoidal Surgery
Surgery within 7-8 days of onset preferred
- Endoscopic or microscopic approach
- Decompress optic apparatus
- Evacuate hemorrhage/necrotic tumor
- Obtain tissue for histology
- Earlier surgery = better visual outcomes
- Continue perioperative steroids
10Action Pituitary Hormone Assessment
Once stable - assess function
- Cortisol (usually low - on replacement)
- TSH, Free T4
- LH, FSH, Testosterone/Estradiol
- Prolactin
- IGF-1, GH
- ADH/vasopressin (diabetes insipidus)
- Most patients need long-term HRT
11Outcome Outcomes & Follow-up
Long-term endocrine follow-up essential
- Visual recovery: better if early surgery
- ~80% have permanent hypopituitarism
- ~50% need lifelong steroid replacement
- ~50% need thyroid replacement
- Gonadal hormone replacement common
- Annual MRI surveillance
- Mortality ~5-10% if treated
12Action Conservative Management
If mild symptoms and stable
- Normal or mildly reduced vision
- Stable consciousness (GCS 15)
- No progressive deterioration
- PAS <4
- Patient preference after discussion
- Close monitoring MANDATORY
13Action Conservative Protocol
High-dose steroids + monitoring
- Continue hydrocortisone IV
- Serial visual assessments (daily)
- Serial neuro exams
- Repeat MRI at 3-7 days
- Convert to surgery if deterioration
- ~70% improve without surgery
14Warning Warning: Deterioration
Convert to surgical management
- Worsening visual acuity
- New visual field defect
- Decreasing GCS
- New cranial nerve palsy
- Failure to improve at 7 days
- Path rejoins step 09Shared downstream outcome
- Path rejoins step 10Shared downstream outcome

Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Optimal surgical timing remains debated
- Pregnant patients require modified approach
- May present similarly to SAH - consider LP if uncertain
- Long-term endocrine follow-up essential
- Pediatric presentations rare, not specifically addressed
