Magnetic resonance imaging of the sella turcica before starting treatment with cabergoline. a Coronal plane in T1-weighted image without contrast shows pituitary adenoma measuring 4.0 × 2.5 cm with total invasion of the sphenoid sinus and cavernous sinuses on both sides (black arrow). The left frontal subacute subdural hematoma is visible (white arrow). b Profile image in T1-weighted scan with heterogeneous contrast uptake showing total invasion of the sphenoid sinus with compression of the optic chiasm and invasion of the nasal area (black arrows). c Coronal plane image without contrast showing pituitary macroadenoma with invasion of the sphenoid and cavernous sinuses on the left (black arrows), in the right temporal lobe and senile atrophy (white arrow); discretely dilated ventricles and widening of the brain grooves can be seen
