Resection of an orbital haemangiopericytoma after direct intraoperative injection of 40% N-butyl-2-cyanoacrylate and 60% Lipiodol.

Haemangiopericytoma is a highly vascular tumour, which is a rare soft tissue lesion that may arise anywhere in the body, including the orbit. During its surgical resection, it is too friable for the surgeon to handle and it can bleed severely causing many problems to the surgeon. That is why many surgical approaches have been reported till now, aiming at total excision with minimal blood loss. In this case, total resection of an orbital haemangiopericytoma in a 61-year-old Caucasian woman, using an intraoperative 23G needle injection of 40% n-butyl-2-cyanoacrylate and 60% lipiodol, is presented. The lesion was directly injected under fluoroscopic visualization, after which it became firm enough to be surgically removed without significant bleeding.
