Abstract: Background: Giant perineural cyst are mostly symptomatic and these mimic pathologic entities. Tarlov cyst (TC) or perineural cysts are the cerebral spinal fluid (CSF) filled sacks usually located at the junction of the dorsal ganglion and posterior nerve root sheaths of spinal nerves. Two patients with lower abdominal pain. An ultrasonographic evaluation in first patient reveals hydrosalpinx. And in second patient pelvic collection. MRI showed multiple, bilateral and almost symmetric tubular presacral space and pelvic extension. Conclusion: MRI is a very useful for evaluation of perineural cyst. It familiarizes the clinicians with unusual presentation of perineural cysts, which helps unnecessary investigations and early detection.
