They are considered histologically benign; however, some have the potential to infiltrate adjacent structures. The aim of this systematic review was to suggest a potential mechanism for the pathogenesis of spinal angiolipomas, along with a useful approach for their preoperative management. Materials and methodsA literature review of cases of spinal angiolipoma was performed. In addition, two of the cases encountered in our practice are presented. The first case refers to a 35-year-old male patient with a history of spinal fusion because of a T9 fracture, while the second concerns a 46-year-old male patient with an epidural mass extending outside the spinal canal, who underwent fine needle biopsy and embolisation of its feeding vessel. ResultsFrom the review of the literature performed, we were unable to identify any correlation between the infiltrative potential and the patients’ demographic and tumour characteristics. ConclusionsAngiolipomas are considered to be sporadic, yet theories concerning their pathogenesis include reaction to harmful stimuli and congenital malformation of the adipose tissue. Fine needle biopsy may be mistakenly considered non-diagnostic, due to the presence of well-differentiated adipocytes. ER -
