Adnexal masses or perineural (tarlov) cysts? Differentiation by imaging techniques: A case report

Firoozeh Ahmadi, Farnaz Akhbari

Abstract


Background: Perineural cysts formed within the nerve-root sheath at the dorsal root ganglion. They are most commonly located in the arachnoid covering the junction of the dorsal ganglion and nerve root. They are usually asymptomatic, incidental findings, usually located in the lumbar and sacral region of the spinal canal. It is important to consolidate the imaging findings of this rare disease so clinicians can become more clinically relevant in the evaluation of these cysts. Case: Herein we report a case of perineural cyst misdiagnosed with hydrosalpinx by pelvic ultrasonography and finally diagnosed with magnetic resonance image. Conclusion: Perineural cyst should be considered, in the presence of bilateral adnexal masses separated from the ovaries in pelvic sonography.
