Intraosseous Hemangioma of the Middle Turbinate Misdiagnosed As a Nasal Polyp

Abstract

Intraosseous hemangiomas account for 1% of all bone tumors and primarily originate from the vertebral column and skull bones. However, intraosseous hemangiomas of the nasal cavity are extremely rare. Here, we report a case of intraosseous hemangioma with a cavernous pattern arising from the middle turbinate that was preoperatively misdiagnosed as chronic rhinosinusitis with polyps. Except for nasal obstruction, there were no specific rhinologic symptoms. The tumor was excised en bloc by the endoscopic endonasal approach without preoperative embolization.

Hemangioma of the Zygomatic Bone

“…4 Histological variants of hemangiomas include capillary, cavernous, and mixed. 1 Most of the intraosseous hemangiomas of facial bones are cavernous hemangiomas. Cavernous hemangioma is composed of thin-walled vascular structures covered by endothelial cells.…”

“…Intraosseous hemangiomas are one of the uncommon benign tumors arising from bone, which mostly occur in the vertebral column and skull bones. 1 Among facial bones, most of the intraosseous hemangiomas grow in the mandible and maxilla, but rarely occur in the zygoma. We present an uncommon patient diagnosed as intraosseous hemangioma of the zygomatic bone and discuss the surgical procedure.…”

“…It can be classified as total or partial, active or inactive, and idiopathic or secondary. 1 Idiopathic condylar resorption (ICR), also known as progressive CR or condylar atrophy, can lead to skeletal and occlusal instability, as well as facial deformities, temporomandibular disorders, and pain. According to Arnett et al, 2,3 there are 3 groups of factors that could cause or contribute to the establishment of CR: malocclusion or improper bite, with premature contacts, which can generate a condylar compression; systemic pathologies (osteoarthritis, hyperparathyroidism, rheumatoid arthritis, hormones) and factors related to condylar anatomy, as well as condylar abnormalities caused by syndrome, trauma, or iatrogenic events.…”

Intraosseous cavernous haemangioma of the inferior turbinate

“…The nasal cavity can harbour a wide variety of tumours, with haemangiomas arising from the soft tissues accounting for approximately 20% of benign nasal cavity tumours 1. Intraosseous haemangiomas represent 0.7–1% of all bone tumours and primarily originate from the spine or skull 1.…”

“…Intraosseous haemangiomas represent 0.7–1% of all bone tumours and primarily originate from the spine or skull 1. Intraosseous cavernous haemangiomas of the nasal cavity are extremely rare with only four cases arising from the inferior turbinate reported in the literature 2–5…”
