MRI showed the tumor regrowth in the original sellar location with a haemorrhagic component involving the left cavernous sinus and encasing the internal carotid artery (Fig. 1).
Coronal (A) and axial (B) CE SE T1W MRI showing a large and heterogeneous sellar mass with lateral and anterior extension involving left orbital apex, orbital fissures, and optic canal. The arrow indicates the encasing of the optical nerve.

The MRI showed a large and dishomogeneus sellar mass with lateral, inferior, and anterior extension involving the cavernous sinus, the sphenoidal bone with sinus invasion, the left orbital apex with orbital fissures, and the optic canal (Fig. 2).
Pulmonary CECT showing several nodular metastases in axial slices of both lungs.

A few months later, because of a worsening of the general clinical situation, dyspnea, and asthenia, a contrast enhanced computed tomography (CECT) scan of the whole body revealed several metastases involving the pulmonary parenchyma bilaterally (Fig. 3).
CECT of the head showing a huge invasive sellar and nasopharinx mass that eroded the sphenoid bone, including clivus, sellar floor, and ethmoid with erosion of the anterior cranial fossa.
