Intraosseous cavernous haemangiomas usually occur in the vertebral and calvarial bones, and account for <1% of primary bone tumours. Nasal cavity intraosseous cavernous haemangiomas are extremely rare. We present a case of a 47-year-old woman with an incidental left inferior turbinate mass noted on CT scan for an unrelated pathology. She had no rhinological symptoms other than a 2-year history of left-sided nasal obstruction. Preoperative imaging failed to determine the aetiology of the mass. The lesion, contiguous with the left inferior turbinate, was successfully resected via an endoscopic approach. Histopathological examination of the resected specimen demonstrated a left inferior turbinate intraosseous cavernous haemangioma.
