"CSF flow studies may be of benefit in determining communication with the pre-pontine cistern or third ventricle, although care must be taken to mistake intracystic turbulent flow due to vascular pulsation from a deficiency in the cyst wall 11."
"Importantly, treating hydrocephalus with with lateral ventricular CSF diversion (e.g. VP shunt) can lead to paradoxical suprasellar cyst expansion which can, in turn, worsen symptoms 4,5."

"Additionally, as expected, given their location, suprasellar arachnoid cysts can also manifest clinically like other suprasellar masses, with visual symptoms from compression and distortion of the optic pathways, and gaze palsies due to compression of the third, fourth and sixth cranial nerves 5-7."

"The indication of surgery in the absence of hydrocephalus or raised intracranial pressure, but in the setting of neuroendocrine dysfunction, gaze palsies, behavioural or development disorders or seizures is less established, as these tend not to improve; see below 6,7."
"As with arachnoid cysts elsewhere, they are very thin-walled (often imperceptible except on dedicated high-resolution T2 imaging) cystic lesions that follow CSF on all imaging modalities. There is no solid component and no enhancement."
