"T1: CSF intensity"
"T2: CSF intensity, may even be brighter than CSF since there is no signal loss from pulsation/flow 8"
"T1 C+ (Gd): no contrast enhancement"
"phase-contrast imaging: decreased CSF flow within the cyst 7"
"DWI: no evidence of restricted diffusion"

"Spinal arachnoid cysts may present at any age. There is no gender predilection."
"Most spinal arachnoid cysts are asymptomatic and are discovered incidentally. Clinical symptoms, if present, may include progressive spastic or flaccid paralysis, pain, weakness, numbness, and/or bladder/bowel incontinence. Symptoms may be exacerbated by postural changes and the Valsalva manoeuvre 13."
"They may be congenital or acquired. Secondary arachnoid cysts are usually due to trauma, haemorrhage, inflammation, surgery or iatrogenic injury like lumbar puncture, injection of anaesthetic or contrast material within the subarachnoid space 3,4,13."
