Strangled by His Nerves-Cervical Plexiform Neurofibroma With Infantile Spinal Neurofibromatosis: Case Report in a 14 Years Old Child.

Background: Neurofibromatoses are a rare group of autosomal dominant tumor suppressor phacomatoses syndromes. Neurofibromatosis type 1 (NF1 or Von Recklinghausen's disease) is the most commonly found type of neurofibromatosis, and constitutes the most commonly found autosomal dominant disease of the nervous system. Case presentation: We report a case of a 14-year-old boy who reported a 3-year-history of a slowly enlarging right lateral cervical mass. He has a medical history of a progressive limping gait disorder with scoliotic attitude. MRI identified a dumb-bell shaped intradural right cervical process through right paravertebral gutter on C2 to C4, a second intradural dorsal mass with the same characteristics through left paravertebral gutter on D4 and D5 and a large tissue-like mass infiltrating the lumbosacral subcutaneous soft tissues. A Surgical excision of the cervical and lumbar masses was performed with a good outcome after surgical excision. Conclusions: This case illustrates the need for a collaboration of both neurological and head and neck surgeons in terms of managing difficulties related to a cervical neurofibroma. Benign plexiform neurofibromas are rapidly growing tumors, particularly in children and adolescents, which makes all the importance of early detection and appropriate treatment. Repeated interventions are usually needed in order to adapt and stabilize the tumors extension.

[Surgical treatment of sacral Tarlov cysts: about 20 cases]. / Traitement chirurgical des kystes de Tarlov sacrés: à propos de 20 cas.

Tarlov cyst or perineural cyst is a local dilation of the subarachnoid space formed within the nerve root and filled with cerebrospinal fluid. There is no consensus on the best treatment of syntomatic sacral perinervous cysts. Many methods have been used to treat these symptomatic lesions, with variable results. We report a case series including 20 patients undergoing surgery for sacral Tarlov cyst. Our results were satisfactory; 80% of patients improved without neurological worsening in the post-operative period. Our surgical technique (sacral laminectomy+cyst puncture+establishment of dural sheat) described for the first time in this study seems to have been effective in the 20 cases reported in our study.
