Intrasellar and suprasellar lesion in a 67-year-old female patient, which is hyperintense in on coronal T2WI (A), hypointense on coronal T1WI (B), and no enhancement is observed on contrast-enhanced T1WI (C) diagnosed as Rathke's cleft cyst pathologically.

MRI evaluation revealed a large cystic intrasellar and suprasellar lesion with superior displacement of the optic chiasm, posterior displacement of the neurohypophysis, and extension to the cavernous sinuses (Figure 1).
MRI after first surgery: Coronal T1WI (A), Coronal post-contrast T1WI (B) and coronal T2WI revealed signs of intracranial hypotension: right and left subdural collections and pachymeningeal thickening and enhancement.

Immediate post-operative follow-up revealed a sphenoidal breach with CSF flow leading to intracranial hypotension which was followed up by MRI (Figure 2) and a surgical revision a few months later to clog it.

Intrasellar lesion in a 22-year-old female patient with a hypointense component on coronal T2WI (A), which is hyperintense on coronal (B) and sagittal (D) T1WI, and without enhancement on coronal contrast-enhanced substracted T1WI (C) diagnosed as Rathke's cleft cyst pathologically.

No mass affect was observed (Figure 3).

Coronal T2WI (A), coronal T1WI (B), coronal contrast-enhanced T1WI (C) and axial FLAIR (D) images in a 73-year-old female patient show cystic intrasellar and suprasellar lesion with a non-enhancing intracystic nodule hyperintense to surrounding fluid on T1 and hypointense on T2.

MRI examination demonstrated a cystic sellar and suprasellar lesion with a non-enhanced intracystic nodule (Figure 4).
Ten-year follow-up of the same patient: Coronal T2WI (A), T1WI (B), post-contrast T1WI (C) and sagittal T1WI (D) show an increase in size of the lesion as well as the intracystic nodule.

MRI revealed an increase in the size of both the cystic lesion and the intracystic nodule showing chiasmatic mass affect and without extension to the cavernous sinuses (Figure 5).

Coronal T2WI (A), T1WI (B), post-contrast T1WI (C), sagittal T1WI (D) and axial FLAIR (E) images demonstrate a sellar and suprasellar lesion with heterogeneous content in the lower part of the lesion and peripheric enhancement.
