Scalp Arteriovenous Malformation (AVM)

Background: We present a case of scalp arteriovenous malformation. Case presentation: A 27-year-old man with a soft mass on his Rt. retroauricular region from few years ago presented with a 10*6 cm pulsatile, soft, compressible mass posterior to the ear. There is bruit over the mass, and powerful pulsation in occipital and superficial temporal arteries of the Rt. side. CT scan revealed a Rt. parieto-occipital scalp mass with normal intracranial content. There is indentation over the outer table in parieto-occipital region. CT Angiography demonstrated normal intracranial blood vessels, very large tortuous tuft of vessels in Rt. parieto-occipital region with huge feeder from Rt. occipital artery and large one from Rt. superficial temporal artery, there is also a small feeder from Lt. side. Cerebral Angiography showed normal intracranial content, huge high flow vascular anomaly in Rt. parieto-occipital region with a very large feeder, most probably occipital artery, from Rt. external carotid artery. Surgical management and post-op studies of the patients are going to be presented. Conclusion: The AVM are rare tumor masses of the scalp for which surgical management should be considered.  Keywords: Arteriovenous malformation (AVM); CT angiography; Management Normal 0 false false false EN-US X-NONE AR-SA /* Style Definitions */ table.MsoNormalTable {mso-style-name:Table Normal; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:Calibri,sans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:Times New Roman; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-theme-font:minor-bidi;}
