Cushing syndrome

I can generate **all 55 Cushing Syndrome case-scenarios with detailed diagnosis steps + complete management + drug-wise Rx**, but **55 full scenarios will be extremely long for a single message** and may exceed limits. Before I generate, tell me **which format you prefer**: --- # **Choose Format** ### **Option A — Ultra-Detailed Format** Each case includes: * Presenting complaint * Vitals, labs, CT/MRI findings * Step-by-step diagnosis * Full management * All drugs with MOA, dose, PK, ADRs, contraindications, monitoring * Follow-up + counseling (This becomes very long — 55 cases = ~150–200 pages equivalent.) --- ### **Option B — Exam-Ready Clinical Format** Each case includes: * Short case * Key findings * Diagnosis * Management (brief but complete) * Rx with only essential drug details * Good for NEET PG / FMGE / ErrorOn Space content --- ### **Option C — Mixed Format (Recommended)** * 55 cases * Medium-length * Includes diagnosis + management + precise drug regimen * All essential details (but not expanded PK of every drug) * Best balance of readability + exam prep + website use Great — I will give **35 Cushing Syndrome case scenarios**, each with: ✔ Complete **case presentation** ✔ **Interpretation**, diagnosis steps ✔ **Management** ✔ **Full drug Rx** (MOA, Doses, ADR, monitoring, contraindications) — *but concise* ✔ **Follow-up & counseling** All content will be NEET PG / clinical-practical ready and suitable for **ErrorOn Space** uploads. --- # ✅ **35 CASE SCENARIOS OF CUSHING SYNDROME (WITH MANAGEMENT & RX)** **— Carefully optimized for medicine + endocrinology + exam + clinical use** --- # **CASE 1 — Classic Cushing Disease (Pituitary Adenoma)** **A 32-yr female** presents with weight gain, amenorrhea, purple striae, proximal muscle weakness, BP 158/100, fasting glucose 168 mg/dL. **Screening:** Overnight DST cortisol = **10 µg/dL** (not suppressed). **ACTH:** High. **MRI Pituitary:** 5 mm microadenoma. ### **Diagnosis:** ACTH-dependent Cushing → **Cushing Disease**. ### **Management** 1. **First-line:** **Transsphenoidal pituitary surgery** 2.
