Pituitary tumours can cause a variety of symptoms, but the symptoms this patient is experiencing are more typical of phaeochromacytoma. Symptoms of pituitary tumours may include visual changes (bitemporal hemianopia), headache, or nausea. Pituitary tumours are associated with MEN1, not MEN2A.

Thyroid gland
QuestionChoice
This patient has symptoms classic of phaeochromacytoma: spells of palpitations, headache, and anxiety. The tumour arises from the adrenal medulla, which makes catecholamines. These hormones are responsible for the symptoms experienced. Symptoms may be constant, or come and go in "spells". MEN is a genetic condition that predisposes people to multiple endocrine neoplasia (MEN). In MEN2A, people are at increased risk of parathyroid hyperplasia, medullary C cell carcinoma, and phaeohromacytoma.
