Sharma M, Velho V, Mally R, Khan SW - Asian J Neurosurg (2015 Jul-Sep)

Bottom Line: Two of our patients had symptoms of cauda equina syndrome, and one had acute sciatica.Symptomatic lumbosacral Tarlov's cyst is a rare lesion, and the presentation can be low back pain, cauda equina syndrome or sciatica.Therefore, this entity should be kept in the differential diagnosis of patients presenting with these symptoms.

ABSTRACT
Lumbosacral perineural cysts (Tarlov's cysts) are nerve root cysts, which are usually asymptomatic and are detected incidentally on imaging. These cysts are rare with an incidence of 4.6%. We report three cases of Lumbosacral Tarlov's cysts, which presented with cauda equina syndrome and radicular pain syndrome. Two of our patients had symptoms of cauda equina syndrome, and one had acute sciatica. Complete excision of the cyst was achieved in two patients and marsupialization of the cyst was done in another patient due to its large size and dense adherence to the sacral nerve roots. All the patients were relieved of the radicular pain with no new neurological deficit following surgery. Symptomatic lumbosacral Tarlov's cyst is a rare lesion, and the presentation can be low back pain, cauda equina syndrome or sciatica. Therefore, this entity should be kept in the differential diagnosis of patients presenting with these symptoms. Complete Surgical excision of these symptomatic cysts is the treatment of choice to achieve a cure.

Mentions: Histopathological examination [Figure 4] case 2 of the cyst wall in all the cases revealed fibro-collagenous tissue intermingled with the nerve fascicles. Fibroblastic proliferation with mononuclear infiltration was occasionally seen. These histopathological features were consistent with the classical description of Tarlov's cyst in the literature. All the patients were relieved of the radicular pain with no new neurological deficit following surgery. Patient with a complex sacral perineural cyst (case 2) developed postoperative CSF leak which was managed conservatively and healed within a period of 10 days. There are no recurrences in all the three cases till the recent follow-up.
