Multisequential multiplanar magnetic resonance images of the brain with and without contrast: axial T2 (a), axial FLAIR-weighted images (b), sagittal T1 (c), and contrasted coronal T1 (d). MRI images reveal a large mass centered on the suprasellar mass, continuous with the infundibulum of the pituitary gland. It is heterogeneously hyperintense on T1-, T2-, and FLAIR-weighted images (arrows in (a-c)), slightly enhanced. Normal pituitary tissue is seen in the bass of the fossa (curved arrow (d)) and a subarachnoid nodular mass in the medulla oblongata (curved arrow (c)).

MRI of the brain and sella showed a large suprasellar mass with cerebral and spinal leptomeningeal spread (Figures 1-3).
Multisequential multiplanar magnetic resonance images of the brain with contrast. Coronal (a) and axial (b-d) contrasted T1 images reveal multiple subarachnoid nodules slightly enhanced (a, b), bilateral nodular lesions in the trigeminal nerves (c), and acoustic-facial bundles (d).

MRI of the brain and sella showed a large suprasellar mass with cerebral and spinal leptomeningeal spread (Figures 1-3).
Multisequential multiplanar magnetic resonance images of the spinal cord without contrast. Sagittal (a) and axial (b) T1-weighted MR images reveal an intradural extramedullar mass having a homogeneous high signal intensity, which is consistent with the T1-shortening effect of melanin located at the level of C3 (arrow). Sagittal T1-weighted MR images (c, d) reveal multiple intradural extramedullar small nodules with high signal T1 intensity (arrow) in the cauda equina.

MRI of the brain and sella showed a large suprasellar mass with cerebral and spinal leptomeningeal spread (Figures 1-3).
Multisequential multiplanar magnetic resonance images of the brain and the spine with and without contrast. Sagittal (a) and axial (b-d) contrasted T1 brain images and sagittal cervical and lumbar spine (e, f) T1 images reveal an increase in the size of the suprasellar tumor (a) and an increase in the number and size of the meningeal nodular masses in the brain (b-d) and the spine (e, f).

An MRI was urgently done to reveal an increase in the size and number of leptomeningeal seeding complicated by obstructive hydrocephalus (Figure 4).
Thoracic and abdominal CT scan with and without contrast. Unenhanced axial CT scan image (a) shows a well-defined hyperdense intraspinal mass (arrow). Axial (b) and sagittal (c) contrast-enhanced CT images show homogeneously enhanced multiple intraspinal masses (arrows).

The CT scan showed no abnormalities other than well-defined intraspinal masses (Figure 5).
