B) Initiate beta-blocker therapy
C) Prescribe alpha-blocker therapy
D) Begin corticosteroid replacement therapy
E) Monitor symptomatically

Explanations & Answers:

Question Easy Answer: B
Question Easy Explanation: This patient’s symptoms and biochemical findings suggest hypothyroidism, characterised by elevated TSH and low free T4. This condition is usually treated with levothyroxine according to NHS guidelines.

Question Medium Answer: D
Question Medium Explanation: The clinical presentation of headaches and bitemporal hemianopia with a sellar mass on MRI is indicative of a non-functioning adenoma. Such adenomas can cause symptoms through mass effect rather than hormone hypersecretion. NICE guidelines recommend considering transsphenoidal surgery based on clinical symptoms and imaging findings.

Question Hard Answer: C
Question Hard Explanation: The symptoms and imaging findings suggest a pheochromocytoma, a catecholamine-secreting tumour. According to BNF recommendations, initiating alpha-blocker therapy is the first step to control blood pressure and prevent intraoperative complications before any surgical intervention.

Medical fact of the day: Did you know that acromegaly is most commonly caused by a benign pituitary tumour known as a somatotroph adenoma? Despite its insidious onset, timely diagnosis and management can significantly improve patient outcomes and quality of life.
