Pituitary macroadenoma is the most common suprasellar lesion in adults. If symptomatic, it is managed surgically via transsphenoidal resection. Patients commonly present with headache and visual disturbances. If the tumour is large enough, it may have mass effect and patient may present with symptoms of elevated intracranial pressure like severe headache, nausea and vomiting. Functional adenomas may cause endocrine dysfunction. Here, we present a case of pituitary macroadenoma in a young adult female who presented with headache. Initial CT and MRI revealed a pituitary macroadenoma. However, repeat imaging done preoperatively showed complete regression of the lesion and a normal appearing pituitary gland.
