Lumboradiculopathy Caused by a Solitary Spinal Epidural Cavernous Angioma: Case Report and Meta-Analysis

Background: Lumboradiculopathy caused by Spinal epidural angioma is a very rare entity. Objective: The aim of the study is to collect clinical and radiological findings that may help to evoke such diagnosis. Case Report and Analyses of the Literature: Clinical case report about a 52- year-old patient and a literature review on Google Scholar, Medline Embase, was made. We were then able to carry out a meta-analyses. Keywords used are as follows: back pain due to cavernous and epidural cavernous hemangioma or angioma. Thirty- six cases were kept on file between1990 and 2010, 19 males and 17 females, i.e. a 4 /5 (0.77) sex-ratio. The diagnosis period was from 3 months to 10 months with an average equal to 22 months for non-decompensated types (n=16 ) and from 2 to 21 days with an average of 6 days (n=5 ) for decompensated types. A cavernoma preoperative presumptive diagnosis was only carried out in 19.45% (n=7). A disk herniation was described in 4 cases, i.e. 11%, and a neurinoma in 3 cases, i.e. 8.3%. MRI showed a hypointense or isointense lesion on T1 in 23 cases, accounting for 71.87% (n=32) T1Gadoliumenhancement in 21 cases accounting for75% (n=28) and hyperintense on T2 weighted sequences in 25 cases, accounting for 89.30% and hypointenseT2 weighted; i.e. 3.44% (n=28). Conclusion: Persistent lumboradiculalgia shall lead us to evoke such diagnostic certainty and will help to prevent cavernoma preoperative bleeding.
