Figure 2.

(a) Coronal post-gadolinium with fat saturation T1-weighted magnetic resonance (MR) image shows sellar and suprasellar mass measuring approximately 2 cm × 1.2 cm × 1.5 cm (anteroposterior × transverse × craniocaudal) and causing mild-to-moderate mass effect in the optic chiasm. (b) Coronal post-gadolinium T1-weighted MR image 4 months after the resection of the neuroendocrine tumour shows homogeneously enhancing large sellar mass with significant interval decrease in size compared to one in A. The residual enhancing tumour process currently measures 1.6 cm × 1.3 cm × 0.8 cm against the prior measurement of 2 cm × 1.3 cm × 1.8 cm (anteroposterior × transverse × craniocaudal)
