Intraosseous hemangioma of the zygomatic bone. A case report

Challenges and Management of Capillary Intraosseous Hemangioma in the Mandibular Symphysis: A Case Report

Capillary intraosseous hemangioma is a benign vascular neoplasm that affects bone tissue, yet its occurrence in the jaw bones has been seldom reported in the literature. We present a case of a capillary intraosseous hemangioma located in the mandibular symphysis of a 28-year-old male. Initially addressed by the patient's dentist as an infectious lesion of endodontic origin, the sudden worsening of the condition, marked by the development of a rapidly expanding exophytic mandibular lesion and tooth mobility, led to the consideration of various potential diagnoses. Subsequently, an incisional biopsy was performed, triggering multiple episodes of recurrent bleeding, leading to several visits to the emergency department, and prompting an urgent status upgrade for the patient. Upon the histological diagnosis of vascular neoplasm, the patient underwent the excision of the lesion, with a favorable and uneventful evolution, although with expected sequelae. As a result, a temporary prosthetic solution, comprising a Maryland Bridge, was implemented, with plans for guided bone regeneration and implant-supported fixed dental prostheses currently in progress. This case underscores the diagnostic and therapeutic challenges associated with this rare condition. Consequently, achieving the optimal outcome for the patient largely depends on a multidisciplinary approach, emphasizing the critical importance of thorough preoperative assessment, along with a well-devised treatment plan and rapid intervention.

Intraosseous Venous Malformation of the Zygomatic Bone: Comparison between Virtual Surgical Planning and Standard Surgery with Review of the Literature

Intraosseous venous malformations affecting the zygomatic bone are infrequent. Primary reconstruction is usually accomplished with calvarial grafts, although the use of virtual surgical planning, cutting guides and patient-specific implants (PSI) have had a major development in recent years. A retrospective study was designed and implemented in patients diagnosed with intraosseous venous malformation during 2006–2021, and a review of the scientific literature was also performed to clarify diagnostic terms. Eight patients were treated, differentiating two groups according to the technique: four patients were treated through standard surgery with resection and primary reconstruction of the defect with calvarial graft, and four patients underwent resection and primary reconstruction through virtual surgical planning (VSP), cutting guides, STL models developed with CAD-CAM technology and PSI (titanium or Polyether-ether-ketone). In the group treated with standard surgery, 75% of the patients developed sequelae or morbidity associated with this technique. The operation time ranged from 175 min to 210 min (average 188.7 min), the length of hospital ranged from 4 days to 6 days (average 4.75 days) and the postoperative CT scan showed a defect surface coverage of 79.75%. The aesthetic results were “excellent” in 25% of the patients, “good” in 50% and “poor” in 25%. In the VSP group, 25% presented sequelae associated with surgical treatment. The operation time ranged from 99 min to 143 min (average 121 min), the length of hospital stay ranged from 1 to 2 days (average of 1.75 days) and 75% of the patients reported “excellent” results. Postoperative CT scan showed 100% coverage of the defect surface in the VSP group. The multi-stage implementation of virtual surgical planning with cutting guides, STL models and patient-specific implants increases the reconstructive accuracy in the treatment of patients diagnosed with intraosseous venous malformation of the zygomatic bone, reducing sequelae, operation time and average hospital stay, providing a better cover of the defect, and improving the precision of the reconstruction and the aesthetic results compared to standard technique.

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.

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.

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.

Primary intraosseous cavernous hemangioma of the clivus: case report and review of the literature

Primary intraosseous hemangiomas are benign, vascular malformations that account for approximately 1% of all primary bone neoplasms. These tumors are mostly found in vertebral bodies and are rarely seen in the calvarium, where they represent 0.2% of bony neoplasms. When found in the skull, they tend to present with vague symptoms and do not have the typical radiological findings suggestive of hemangiomas. Because of this, these tumors can be missed in many cases or may be misinterpreted as more ominous lesions like multiple myeloma or osteosarcoma. Involvement of the skull base is exceedingly rare, and presentation with cranial nerve unilateral polyneuropathies has not been reported. We report a patient case with review of recent pertinent literature.

Capillary hemangioma: An occasional growth of attached gingiva

The capillary hemangiomas represent developmental hamartomatous lesions of vascular tissue and their growth stops after certain period of time, following which some of the hemangiomas may involute. Capillary hemangiomas are common tumors of infancy and adolescents. Although head and neck are the most prevalent sites for origin of hemangiomas, they are very rarely observed arising on attached gingiva. This paper presents a rare case report of capillary hemangioma on attached gingiva of posterior maxilla in an adult female. Surgical management was done by Widman's periodontal flap operation with satisfactory uneventful healing. The characteristic clinical and histo-pathologic features of vascular tumors and malformations, especially capillary hemangiomas are discussed.

Case report: Periorbital intraosseous hemangiomas

Hemangiomas are hamartomatous proliferation of vessels. Intraosseous hemangiomas of the facial bones are rare and most commonly involve the zygoma, maxilla, mandible, and the nasal bones. A “sunburst” pattern is a typical appearance on CT scan and MRI and therefore a biopsy is not always necessary. Surgery is usually performed in symptomatic cases. The authors describe five typical periorbital intraosseous hemangiomas with a brief review of literature.

Co-occurrence of intraoral hemangioma and port wine stain: A rare case

Hemangiomas are neoplastic proliferations of endothelial cells, characterized by a period of growth after birth, and eventual spontaneous involution. The course can be uneventful with spontaneous resolution; or it may be marked by complications such as infection, bleeding, ulceration, visual defects and feeding difficulties. Apart from these, rare life-threatening complications such as congestive heart failure and consumption coagulopathy may also be seen. Although hemangiomas commonly occur in the head and neck region, intraoral occurrence is relatively rare. A port wine stain is defined as a macular telangiectatic patch which is present at birth and remains throughout life. They may be localized or extensive, affecting a whole limb. This article reports a rare case of co-occurrence of port wine stain with intraoral hemangioma.

A mixed neoplasm of intraosseous hemangioma with an ameloblastoma: a case of collision tumor or a rare variant?

Hemangiomas of the head and neck are considered to be benign tumors of infancy that are characterized by a rapid growth phase with endothelial cell proliferation, followed by gradual involution. Central hemangiomas are a rare occurrence and even rarer are the hybrid tumors of central hemangiomas with odontogenic tumors such as ameloblastomas. This paper reports a case of one such hybrid tumor in a middle aged adult clinical presenting as a mandibular swelling with indistinct mixed radiographic presentation and histopathologically comprising of intimately associated hemangiomatous vascular channels and typical ameloblastic areas. To the authors' knowledge this is the sixth case of such a hemangiomatous ameloblastoma which has been reported till date.

Massive craniofacial intraosseous vascular malformation resembling cystic angiomatosis: report of 2 cases and review of the literature

Cystic angiomatosis of bone is a rare condition of multifocal angiomas of the skeleton. The condition is believed to be congenital, grows slowly and starts in first decades of life. Two cases of progressive bimaxillary enlargement, presented here with a history of slowly enlargement of facial bones when they were 9 and 6 year old, respectively. Radiographic evaluation of the craniofacial bones revealed aggressive hypertrophy with severe displacement of the teeth. The histopathological evaluation of the gross specimen showed vital bone containing capillary and cavernous spaces with endothelial lining. Aggressive cystic angiomatosis of the facial bones was described here as the most probable diagnosis.

Intraosseous 'haemangioma' of the zygoma: more appropriately termed a venous malformation

Vascular anomalies often affect the soft tissues and primary intraosseous lesions are uncommon, with only 33 cases reported in the zygoma. Intraosseous vascular anomalies of the zygoma have traditionally been designated 'haemangiomas' with little attempt to clarify the specific type of the lesion. Recently, specific immunohistochemical markers such as erythrocyte type glucose transporter protein 1 (GLUT-1) have been described to differentiate haemangiomas and vascular malformations. The authors report a case of intraosseous venous malformation of the zygoma and provide supporting evidence to justify the nomenclature. The literature on zygomatic 'haemangiomas' is critically reviewed and the basis for their proper designation as venous malformations highlighted.

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.

Reconstruction of intraosseous hemangiomas of the midface using split calvarial bone grafts

BACKGROUND

Intraosseous hemangiomas are benign lesions that usually occur in the vertebral column and the calvaria. They are rare in the midface, with only 22 zygomatic and 26 nasal bone hemangioma cases described in the literature. Methods of reconstruction of craniofacial defects after surgical removal of these tumors have been inconsistent.

METHODS

The authors report long-term follow-up in three cases of midface intraosseous hemangiomas all treated in a similar fashion: surgical excision of the tumor with a small margin of normal bone and primary reconstruction using split calvarial bone grafts.

RESULTS

Clinical, photographic, and computed tomographic assessment (cases 1 and 2) documents no recurrence and maintenance of the result with a mean 5-year follow-up. To the authors' knowledge, this represents the longest follow-up of a patient series with hemangiomas of bone treated with primary reconstruction in the plastic surgery literature (Wolfe and Berkowitz did report on a single case with 4-year follow-up without recurrence). We recommend replacing like with like. Primary bone grafting with autogenous cranial bone was used to replace areas where original bone was thin, but full-thickness bone was used in areas where original bone was thick. Full-thickness cranial bone grafts may be superior to split cranial bone with regard to long-term volume maintenance.

CONCLUSIONS

Preoperative computed tomographic scanning should lead to the appropriate diagnosis. Proper diagnosis should lead to appropriate treatment, which includes total excision and primary bone grafting of the defect to prevent soft-tissue contraction.

Intraosseous Hemangioma of the Maxillofacial District: Clinical Analysis and Surgical Treatment in 10 Consecutive Patients

The aims of this study are to illustrate functional and esthetic results obtained with different surgical strategies and to report a review of the relevant literature. There were 6 female patients and 4 male patients included in this study, with an average age of 35.7 years. Zygomatic bone was affected in six cases, the mandible in two cases, the medial orbital wall in one case, and the upper jaw in one case. In all 10 patients, surgery consisted of a wide excision of the intraosseous hemangioma with margins of 3 mm at least to ensure complete removal. Immediate reconstruction was carried out in 5 of the 10 patients. An analysis indicates that intraosseous hemangiomas of the maxillofacial area are rare; diagnosis can be difficult and is mainly based on computed tomography scans. Surgical excision, with previous angiography and embolization in cases of intraosseous hemangioma with a larger dimension or abnormal blood supply, is the treatment of choice.

Intraosseous hemangioma of the zygoma

Zygomatic hemangioma is an extremely rare, benign, slow-growing tumor occurring mostly in adult women. The radiologic findings are diagnostic. Total excision of the tumor with primary reconstruction of the defect is the preferred treatment modality. We present a case of zygomatic hemangioma and a brief review of the literature.

Congenital cavernous angioma of the temporal bone: case report

BACKGROUND

Congenital cavernous angioma is a very rare tumor that occurs in young adolescents. We describe a rare case of congenital cavernous angioma of the temporal bone in a neonate. Ultrasonography (US) and dynamic magnetic resonance imaging (MRI) were helpful in its diagnosis.

CASE DESCRIPTION

US and MRI of the fetus in the 32nd week of gestation revealed a large extra-axial tumor with intra- and extracranial extension. After the birth, US and dynamic MRI studies were performed in addition to conventional CT and MRI. These findings were compatible with cavernous angioma. The mass was totally removed on the fourth day of life and was found at surgery to originate from the skull. Histopathological diagnosis was cavernous angioma. The usefulness of US and dynamic MRI are also discussed.

CONCLUSION

US and dynamic MRI are useful, less invasive techniques for diagnosing this rare type of tumor. They provide useful information to differentiate calvarial mass lesions in neonates.

Primary Intraosseous Skull Base Cavernous Hemangioma: Case Report

Primary intraosseous cavernous hemangiomas (PICHs) of the skull base are extremely rare tumors. These lesions are most common in the frontal and parietal bones of the calvarium. The authors describe a 40-year-old female who presented with progressive headaches. Serial imaging revealed a contrast-enhancing intraosseous lesion of the lateral body of the sphenoid bone and the greater wing associated with encroachment of the inferior cavernous sinus and mild posterior displacement of the cavernous carotid artery. Follow-up imaging 9 years later revealed slow growth of the lesion. The patient underwent complete excision of the PICH through an extradural frontopolar approach. Pathological examination revealed an intraosseous cavernous hemangioma. PICHs of the skull base can mimic other more common skull base lesions and thus can be difficult to diagnose preoperatively. Diagnosis is usually made at surgery. The authors review the literature regarding the clinical presentation, radiological characteristics, pathological features, and surgical management of PICHs.

Thoracic outlet syndrome caused by first rib hemangioma

We report a case of first rib hemangioma that caused thoracic outlet syndrome. A 50-year-ole woman who was admitted to our hospital with a clinical diagnosis of thoracic outlet syndrome presented with fullness and easy fatigue of her right arm. Her right arm discomfort was associated with intermittent engorgement of superficial veins over the shoulder girdle. A chest radiograph revealed an enlargement of the anterior aspect of the first rib with fine bony trabeculations. Computed tomography scan showed contrast enhancement over the enlarged rib. Our tentative preoperative diagnosis was a benign first rib hypertrophic change, such as an old fracture with exuberant callus formation. A right-arm venogram revealed a patent subclavian vein with an extrinsic compression, which occluded on arm abduction. The findings of neural conduction studies of both upper extremities were symmetric and normal. The patient agreed to surgery because of the occlusive condition of the subclavian vein on arm abduction and progressive arm weakness in recent months. Segmental transection of the offending portion of the enlarged first rib was complicated by difficulty in isolating the whole length of the compressed but normal-appearing subclavian vein by our initial transaxillary and infraclavicular approaches because the medial aspect of the subclavian vein was obstructed by the enlarged first rib, which extended medially to the junction of the right jugular and subclavian veins. Successful segmental transection of the enlarged first rib was finally accomplished by combined transaxillary, infraclavicular, and supraclavicular approaches. A moderate amount of rib bleeding from resection ends was noted during segmental resection of the enlarged first rib, resulting in local hematoma formation. A 470-mL bloody discharge was collected from the vacuum ball inserted via the transaxillary route during her 12-day hospitalization. Pathologic examination revealed an intraosseous hemangioma. The patient had a prolonged course to partial recovery of her arm numbness, but signs of venous compression were much improved at 6 months' follow-up. Although hemangioma is benign, its hypervascular nature may cause catastrophic intraoperative bleeding.

Intraosseous hemangioma of the vomer: a case report

We describe an unusual case of intraosseous hemangioma of the vomer. The lesion had a characteristic radiographic appearance, especially on the computed tomographic scan. The two most interesting points in this case were the rarity as a site for the occurrence of hemangioma and the successful extirpation of the tumor via the Le Fort 1 osteotomy approach without embolization of the feeding vessels. The benefits of this approach included the wide surgical field afforded deep in the midface region, which was important for controlling bleeding, as well as the complete extirpation of the tumor.

Use of hydroxyapatite for reconstruction after surgical removal of intraosseous hemangioma in the zygomatic bone

Two rare cases of intraosseous hemangiomas in the zygomatic bone that were repaired after surgical removal of the tumor with hydroxyapatite implants are reported. Case 1 is a 42-year-old woman, and case 2 is a 46-year-old man. They complained of swelling in the right cheek. An intraosseous tumor in the right zygomatic bone was observed in both patients. The tumor was resected, and hydroxyapatite was employed to repair the defect caused by removal. After 4 years since the operation in case 1 and 8 months in case 2, the patients show satisfactory cosmetic appearance. Hydroxyapatite implant was useful for reconstruction of the defect after surgical removal of hemangiomas in the zygomatic bone.
