“…Higher differences were observed among patients with symptomatic cysts. Based on the cumulative analysis done by Oaklander [5] with data presented by other authors [1], [7], [11]–[14], the cyst was found in 29 females (78%) out of 37 patients. Higher female predominance was also confirmed by neurosurgical data since 102 (84%) out 122 patients who underwent precutanous sealing of perineurial cysts were females [3].…”

The spinal perineurial cyst (Tarlov) is a dilatation between the perineurium and endoneurium of spinal nerve roots, located at level of the spinal ganglion and filled with cerebrospinal fluid but without communication with the perineurial subarachnoid space. The aim of the study was to evaluate it incidence among East-European patients. The retrospective data collected during various magnetic resonance spinal examinations and stored on the picture archiving and communication system was analyzed for an incidence of perineurial cysts. From among 842 patients that underwent examination, 75 cases perineurial cysts were revealed. In 22 cases single anomalies were found. In remaining 53 cases, multiple uni- or less frequently bilateral changes were noted. The most common position was the sacral canal, particularly the level of S2 and S3. Occasionally, cysts were also visible on the cervical, thoracic and lumbar level. Incidence of sacral perineurial cysts was significantly higher in females than in males. Similar data was found for single and multiple changes despite of their localization. Insignificant changes were seen for patient age and cyst size. Perineurial spinal cysts were the most frequently observed on the sacral level and such changes were more common in females.

“…Selon Lotan et al [3] le diagnostic imagérique à la myélographie, au scanner ou à l'IRM en préopératoire reste un problème malgré l'amélioration des moyens d'investigation. Pour Younes [8], le scanner est moins contributif au diagnostic; mais il peut parfois montrer l'anomalie sous forme d'une grosse racine, d'une racine bilobée ou dédoublée au niveau de récessus latéral. Pour notre patient, l'IRM a plutôt montré un aspect de grosse racine pris pour un kyste de Tarlov.…”

“…La chirurgie de cette lésion est controversée. Le traitement chirurgical consiste à pratiquer une libération large des racines (foraminectomie, arthrectomie, voire une pédiculectomie) et une résection d'une éventuelle hernie associée [8]. Une foraminectomie seule a été faite dans notre cas sans discetomie car la mobilisation de la racine médiale était difficile.…”

De découverte per-opératoire pour hernie discale, les anomalies d’émergence radiculaires constituent une entité rare. La présentation clinique est généralement identique à celle d'une radiculopathie. Nous rapportons le cas d'un patient âgé de 35 ans présentant une sciatique droite S1 hyperalgique rebelle aux multiples médications. L'IRM du rachis lombo-sacré avait mis en évidence une discopathie protrusive de petit volume en L5 S1 droite et un aspect de grosse racine ou de kyste de Tarlov au niveau de l’émergence droite de S1. Une fenestration inter lamaire L5-S1 droite avec une ablation du ligament jaune a montré une émergence radiculaire double au niveau de l'espace retro-discal. Un geste de foraminostomie a été réalisé sans discectomie. L’évolution a très favorable avec une rétrocession dès le lendemain. L'analyse pré-opératoire fine et rigoureuse de l'imagerie est indispensable. Une bonne libération améliore l’état clinique du patient. Y penser en cas de sciatique hyperalgique sans Lasègue.

“…The spine lumbar CT scan of our patients did not allow thinking of conjoined root, they suggested a degenerative disc disease. However, for Younes (2009), although the scan is less contributing to the diagnosis, it can sometimes show the anomaly in a form of big root, bilobate root or duplicated at the level of lateral recessus (13). This aspect of a big root was objectified on patient No.1 MRI.…”

Background & Aim: Conjoined nerve root is defined as two adjacent nerve roots that share a common dural envelope at some points during their course from the thecal sac. This study reports our experience of conjoined roots involving three cases in Dakar. Methods & Materials/Patients: This is a consecutive study from 2013 to 2015 involving patients supported for disc herniation and who have presented conjoined nerve root anomalies. Results: Three patients aged 32, 35 and 55 including two men have been concerned. Clinical analysis was done on sciatica with neuropathic occurrences in one case and lumbosciatica in two cases. The Lasegue sign was present in two patients at 45°. All three patients benefited a lumbar computerized tomography (CT scan) highlighting a degenerative disc disease with two in L5S1 space and one in L4L5 space. The imaging has not objectified radicular emerging anomalies. MRI objectified only one big root. A surgical root decompression was realized through interlaminar discectomy approach; foraminotomy and full laminectomy enabling diagnosis in intraoperative period. The evolution was favourable in all three cases with full recession of symptomatology. Conclusion: This study is the first Senegalese series on the lumbo-sciatica by anomaly of root emergence and highlights especially the difficulties for the diagnosis of these anomalies like other sub-Saharan African countries where expansion of MRI for the diagnosis is low, and still very expensive. MRI provides guidance signs and a large root appearance can warn about the existence of these anomalies. A good root release improves the symptoms.
