Intraosseous zygomatic hemangioma

Computer guided resection and reconstruction of intra-osseous zygomatic hemangioma: Case report and systematic review of literature

OBJECTIVES

to systemically integrate the available data on various published treatment strategies for intraosseous hemangioma of the zygoma in an updated comprehensive systematic review, and to present a new case of treated resection and immediate reconstruction using computer guided patient specific composite graft.

CASE PRESENTATION

A 29 years old female patient with intraosseos zygomatic hemangioma treated using computer guided resection and immediate reconstruction. The resection was performed using a resection template constructed based on preoperative 3D planning. The reconstruction was performed using ramus bone graft and titanium mesh. The patient was followed up for 3 years with no complications.

METHODS

An electronic search was performed on 3 data bases; additional hand search of bibliographies of selected articles was performed. Eligibility criteria include human studies presenting intraosseous zygomatico-orbital hemangioma with clearly reported therapeutic strategies.

RESULTS

53 articles with 73 cases were included. The lesion was highly prevalent in females compared to males (2.28:1). Fifth decade represents the highest prevalence with mean age of 44.1 ± 1.8 years. The main patient concern was swelling and facial deformity. Total tumor resection can assure no recurrence, while partial resection and curettage are associated with high recurrence rate.

Skeletal cavernous hemangiomas of the frontal bone with orbital roof and rim involvement

Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect.

An Algorithm for Managing Intraosseous Vascular Anomalies of the Craniofacial Skeleton

BACKGROUND

Intraosseous vascular anomalies (IOVA) are rare in the craniofacial skeleton and present a diagnostic and therapeutic challenge. This study aims to describe the clinical management based on a large case series.

METHODS

A retrospective chart review was performed and 9 IOVA were identified over a 15-year period. Data on demographics, diagnostic features, clinical management, and outcomes were reviewed.

RESULTS

Five frontal bone IOVA and 4 orbital IOVA were identified. The postoperative follow-up ranged from 4 months to 4 years. All 9 lesions were diagnosed with computed tomography (CT) imaging. Magnetic resonance imaging (MRI) was used to delineate soft tissue involvement in 2 patients presenting with oculo-orbital dystopia and ophthalmoplegia. En bloc excision was performed in all patients. Preoperative interventional embolization was critical in the successful resection of an orbital IOVA following 2 previously failed attempts that were aborted secondary to hemorrhage. Intraoperative 3-dimensional stereotactic navigation was used for the accurate en bloc excision of a frontal IOVA to prevent injury to the frontal sinus. Reconstruction of esthetic and functional deformities was successfully accomplished.

CONCLUSION

The diagnosis of IOVA relies primarily on clinical assessment and CT imaging. Further interpretation of the involvement of periorbital, facial, and intracranial soft tissue is best defined by MRI. Multidisciplinary care with interventional radiology and neurosurgery must be considered for ensuring the safe and adequate en bloc excision of craniofacial IOVA.

Intraosseous Venous Malformations of the Zygoma: Report of 4 Cases and Literature Review

OBJECTIVES

As intraosseous venous malformations (IVMs) of the zygoma are very rare and clinical features are not typical, a correct preoperative diagnosis may be difficult to make. This study presents 4 cases of IVM of the zygoma and gives a review of their clinical manifestations, radiographic features, preoperative diagnosis, and differentials.

METHODS

The report of 4 cases was performed with an average 6-year follow-up. Medical records including clinical, radiographic, and histopathological information were reviewed.

RESULTS

All the patients were mid-aged women with a complaint of an enlarging mass over the midface. They all failed to receive a definite preoperative diagnosis, and the diagnoses of IVM in all patients were made via pathological evidence. Although they received different surgical treatments, all the follow-up results (2~12 years) were satisfactory.

CONCLUSION

Intraosseous venous malformations of the zygoma are benign lesions caused by abnormal vessel morphogenesis. Patients usually present in their 40s with a tender or painless swelling of the zygoma. The key to the diagnosis is the typical sunburst pattern of radiating trabeculae with intact cortices on computed tomographic scans. Intraosseous venous malformations should be differentiated from other lesions, including intraosseous meningioma, fibrous dysplasia, osteochondroma, osteosarcoma, and ossifying fibroma.

Zygomatic Intraosseous Hemangioma: Case Report and Literature Review

Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area. They have a tendency to bleed briskly upon removal or biopsy, making preoperative detection of the vascular nature of the lesion of significant importance. There are four variants: (1) capillary type, (2) cavernous type, (3) mixed variant, and (4) scirrhous type. Generally most common in the vertebral skeleton, they can also present in the calvarium and facial bones. In the head, the most common site is the parietal bone, followed by the mandible, and then malar and zygomatic regions. Intraosseous hemangiomas of the zygoma are rare entities with the first case reported in 1950 by Schoenfield. In this article, we review 49 case reports of intraosseous hemangioma of the zygoma, and also present a new case treated with excision followed by polyether-ether ketone implant placement for primary reconstruction.

Cranio-orbital primary intraosseous haemangioma

PURPOSE

Primary intraosseous haemangioma (IOH) is a rare benign neoplasm presenting in the fourth and fifth decades of life. The spine and skull are the most commonly involved, orbital involvement is extremely rare. We describe six patients with cranio-orbital IOH, the largest case series to date.

PATIENTS AND METHODS

Retrospective review of six patients with histologically confirmed primary IOH involving the orbit. Clinical characteristics, imaging features, approach to management, and histopathological findings are described.

RESULTS

Five patients were male with a median age of 56. Pain and diplopia were the most common presenting features. A characteristic 'honeycomb' pattern on CT imaging was demonstrated in three of the cases. Complete surgical excision was performed in all cases with presurgical embolisation carried out in one case. In all the cases, histological studies identified cavernous vascular spaces within the bony tissue. These channels were lined by single layer of cytologically normal endothelial cells.

DISCUSSION

IOCH of the cranio-orbital region is rare; in the absence of typical imaging features, the differential diagnosis includes chondroma, chondrosarcoma, bony metastasis, and lymphoma. Surgical excision may be necessary to exclude more sinister pathology. Intraoperative haemorrhage can be severe and may be reduced by preoperative embolisation.

Intraosseous Venous Malformations of the Facial Bone: A Retrospective Study in 11 Patients

Objectives:

To investigate the clinical symptoms, computed tomography (CT) features and treatments of intraosseous venous malformations (IVM) that occur in the facial bone.

Methods and Results:

Eleven patients with facial IVM were treated with two surgical techniques, excision ( n = 4) or curettage ( n = 7). No recurrence was encountered at follow-up (45.8 ± 16.0 months). Postoperative deformities were left in two paediatric patients who were treated with excision.

Conclusions:

The diagnosis of IVM can be difficult and is mainly based on clinical symptoms and CT features. IVM should be differentiated from other lesions, including ameloblastoma, odontogenic cysts, osteosarcoma, aneurysmal bone cysts and arteriovenous malformations, among others. Conventional block biopsy should be replaced by fine needle aspiration cytology for further diagnosis. Curettage is a more appropriate method for IVM compared with excessive en-bloc osteotomy, while transosseous embolo-sclerotherapy may be a promising alternative method. Finally, the terminological confusion between ‘intraosseous haemangioma’ and ‘intraosseous venous malformation’ should be avoided according to the binary classification.

[Intradiploic cavernous hemangioma of the calvaria: case report and review of the literature]

We report the case of a 31-year-old patient who had had frontal cephalalgias for several years. CT and MRI anatomical imaging objectified a frontal osteolytic tumor respecting the osseous external table but compressing the superior sagittal sinus. Total en bloc resection of the tumor associated with titan cranioplasty was performed. The postoperative course was uneventful. Three months after surgery the patient no longer reported headache. The anatomical and pathological results concluded in intradiploic cavernous hemangioma. We discuss this case and others described in the literature.

Intraosseous hemangiomas

Intraosseous hemangiomas are classified as benign tumors of vascular nature. Some authors describe them as hamartomas. They originate and expand inside bone structures. They are usually congenital, rarely of posttraumatic origin. In the Maxillo-Facial Surgery departments of the Universities of Rome "La Sapienza" and "Tor Vergata," from 1990 to 2004, 11 cases of intraosseous hemangioma have been diagnosed. In 6 cases, the neoplasm localized in the zygomatic region; in 3 cases, at the mandible level; in 1 patient, in the maxillary site; and in 1 patient, in the frontal bone. Literature review and the case of a male patient affected by left orbitozygomatic hemangioma are described.

Three-dimensional reconstruction after removal of zygomatic intraosseous hemangioma

INTRODUCTION

Intraosseous hemangioma, especially in the zygomatic area, is a very rare pathologic condition among the osseous tumors of the head and neck area. Clinical presentation includes a painless mass with progressive growth and hard consistence. Diagnosis is performed by means of computed tomography (CT). Treatment includes radical en bloc surgical excision with healthy bone margins in order to avoid blood loss. Previous embolization is not necessary. Bony defect reconstruction must be performed to avoid secondary deformities.

CASE REPORT

We present a case report of a 30-year-old female presenting a progressive painless swelling in the malar and zygomatic regions. CT scan demonstrated a right zygomatic lesion that extended into the orbital floor and lateral orbital wall, affecting also the zygomatic arch. The biopsy revealed an intraosseous hemangioma. Treatment was performed including an en bloc resection with healthy bony margins and primary reconstruction with calvarian bone graft in association with galea-pericranium flap.

Intraosseous hemangiomas of the facial bone

BACKGROUND

Hemangiomas arising in the soft tissue are common in the head and neck region, but intraosseous hemangiomas of the facial bone are rare.

METHODS

The authors conducted a retrospective study investigating the clinical features, management, and outcomes for seven patients with facial bone hemangiomas.

RESULTS

Three of the hemangiomas arose in the orbital bones, two arose in the mandible, one arose in the frontal bone, and one arose in the zygoma. The mean follow-up was 3 years 9 months. During the first operation, total tumor resection was performed for two symptomatic patients, and partial resection with superficial osteotomy was performed for the remaining five individuals with facial contour deformity. Three patients who underwent partial resection achieved long-term aesthetically satisfactory results without recurrence; the other two developed recurrent tumors and underwent subsequent en bloc resection. No evidence of recurrence was observed in cases where primary or secondary complete tumor resections were performed.

CONCLUSIONS

Although complete tumor resection represents a definitive treatment for facial bone hemangiomas, conservative partial resection offers a simple method of restoring facial contour with minimal side effects. Although it appears that recurrence cannot be avoided entirely, partial resection should be considered for patients who seek surgery for cosmetic reasons.
