In children who apply to the brain and neurochirurgical clinic with the mass in the lumbosacral area, the pathologies of congenital spinal malformations, primarily the meningosal section, are thought. However, the distinctive diagnoses of this area may also include lipoma, congenital vascular malformations. In this presentation, a 5-year-old child, who applied with swelling showing painful growth in the lumbosacral area and has been operated with a pre-diagnosis of lipoma due to the absence of spinal disraphism in the radiological images and diagnosed with arteriovenous malformation, is in the light of the patient literature.

However, the differential diagnoses of this region include lipoma and congenital vascular malformations. In this presentation, a 5-year-old pediatric patient who was admitted with a swelling on the lumbosacral region and who was operated for the diagnosis of lipoma due to the absence of spinal dysraphism findings in his radiological images but pathologically diagnosed as arteriovenous malformation in the light of the literature. Keywords: Vascular Malformation; Arteriovenous Malformation; Lipoma; Magnetic Resonance Imaging INTRODUCTION Vascular anomalies are congenital abnormal vascular developmental lesions. Although they were first called vascular birth spots, they were classified by Mulliken and Glowacki in 1982 according to histological, biological behavior and the forms of clinical application of these antibodies (1). They are gathered under two main titles: vascular anomalies, vascular tumors and vascular malformations. Vascular malformations are slowly and quickly divided into two subgroups. Arteriovenous malformations (AVMs) form a group of rapidly flowing vascular malformations. If necessary vascular tumors, malformations can be seen everywhere in the body (2). Very little is known about the origin and pathogenesis of arteriovenous malformations, and it has been that adolescence and trauma have caused the growth of these lesions (3). However, in children who apply to the brain and nerve surgery clinic with soft tissue swelling in the lumbosacral area, congenital spinal malformations, such as the front-plan of the meningosal section, are considered parallel to the usual experiences. This article presents the fact of a 5-year-old boy who applies with a swelling that shows painful and progressive growth in the lumbosacral area and has been diagnosed with arteriovenous malformation.
