Magnetic resonance imaging (MRI) revealed an invasive pituitary macroadenoma extended to suprasellar and compressing the optic chiasm, infrasellarly into the sphenoid sinus, and laterally invading into the left cavernous sinus (figure 1).

The LH and TSH markers were negative. 2 months after the TSS surgery, a gamma knife radio-surgery was done for the patient due to tumor residues in left cavernous sinus (figure 2). During MRI study, they found out about a mass in the brainstem with compressive effect on spinal region (figure 3), pituitary imagine does not differ from the last MRI (figure 2).
