Clinics in diagnostic imaging (34). Invasive pituitary macroadenoma.
A 44-year-old woman presenting with headache and decreased visual acuity was found to have bilateral papilloedema. Radiograph showed an enlarged pituitary fossa. MR scans demonstrated a large solid tumor with central necrosis, and both suprasellar and infrasellar extension. The invasive pituitary macroadenoma was surgically debulked, followed by radiotherapy. The clinical and imaging features of pituitary macroadenomas are discussed.
