Hemangioma of the frontal bone: review of the literature and report of a case

Melanotic Neuroectodermal Tumour of Infancy

Melanotic neuroectodermal tumour of infancy (MNTI) is a locally aggressive neoplasm of neural crest origin. It is primarily a paediatric tumour, and 95% of the cases occur in children below 1 year. The tumour mainly affects the head and neck region. It shows a predilection for the craniofacial sites and the most common site affected is anterior maxilla. Microscopically, it is characterized by a biphasic population of neuroblastic cells and pigmented epithelial cells. Although generally considered as a benign tumour, it can invade the adjacent muscle and bone, causing destruction of the involved site. The rapidity in growth and the aggressive clinical behaviour of the tumour can be deceptive and hence lack of familiarity with the clinical characteristics of the tumour may often lead to an erroneous diagnosis of malignancy. The treatment of choice for MNTI is excision, and it is usually curative. Extensive surgery in a child may interfere with the normal growth and development of the facial structures and reconstruction can be very challenging in infants. Hence, early diagnosis is critical for the effective management. Clinical findings, histopathological features, and differential diagnosis of a classic case of melanotic neuroectodermal tumour of infancy are discussed.

Forty-five-months follow-up of a minimally invasive, interdisciplinary treated hemangioma of the mandible with a high risk of severe bleeding - a case report

BACKGROUND

Hemangiomas are benign tumours, mostly seen in the soft tissues. The intraosseous appearance is rare, in particular in the jaws they represent a very seldom malformation.

AIM

To present a combined endodontic and surgical management report of a clinical case with a rare intraosseous hemangioma diagnosis in the mandible.

CASE PRESENTATION

This well-documented case report describes the interdisciplinary treatment approach of an intraosseous hemangioma in the left mandible of a 70-year-old male patient. This incidental finding was detected through a routine dental examination. The panoramic radiograph revealed an asymptomatic, apical translucency approximately 15 mm diameter with contact to the mesial root of the tooth 36. The clinical examinations showed no abnormalities. The multifaceted specialized treatments started with the endodontic treatment of the tooth prior to the surgical removal of the lesion and were followed by the histological assessment. As derived from the histologically verified diagnosis, this rare case included the risk of severe bleeding complications during therapy.

Surgical Management of a Massive Frontal Bone Hemangioma: Case Report

Intraosseous hemangiomas are rare, benign tumors that can arise from the calvarium. These lesions often invade the outer table of the skull, but typically spare the inner table and intracranial structures. En bloc surgical resection is the standard treatment for intraosseous hemangiomas. However, a piecemeal resection may be required to safely remove the tumor in cases involving the inner table to protect the underlying brain parenchyma and vascular structures. Proper reconstruction is critical to optimize the cosmetic outcome, and a staged procedure allowing implantation of a custom-made implant can be considered for large lesions involving the forehead. We present a case of a patient with a large frontal intraosseous hemangioma with intradural involvement to highlight the surgical nuances of resection and review the existing literature regarding optimal management of these patients.

Posttraumatic skull hemangioma: case report

Intraosseous cavernous hemangiomas of the skull are rare lesions for which the origin is unclear. The authors present a case in which there was a radiologically documented history of trauma preceding the development of a hemangioma in the frontal bone. In a review of the literature the authors found 83 cases of skull hemangiomas, and 43% of the lesions were located in the frontal bone. In 25% of these lesions, previous trauma was reported anamnestically. The present case and radiological findings related to it suggest a causal relationship between trauma and the development of intraosseous hemangioma.

Primary hemangioma of the occipital bone in the region of the torcula--two case reports

Two rare cases of subtorcular occipital bone hemangioma occurred in 26-year-old and 30-year-old female patients. Partial resection was performed in both cases because of the proximity to the torcula. No recurrence was seen at follow-up examination at 9 and 12 months.

Intraosseous hemangioma of the mandible: a case report and review of the literature

Intraosseous hemangiomas are benign lesions, occurring often in vertebra and skull. These lesions can present in the head and neck region being the next most common site with a predominance of mandible. There are approximately seventy intraosseous hemangiomas of mandible in literature reported to date. We present an intraosseous hemangioma of the symphysis mandible. We performed a block resection of the mass preserving the mandibular integrity with no complications. There were no recurrences in the follow-up period of 24 months.

Hemangioma of the mandible presenting as a periapical radiolucency

A case of an hemangioma of the mandible in a 53-yr-old female patient is presented. The lesion was removed, and no atypia or mitotic cells were found. The excision was curative, and the overall prognosis was excellent. A differential diagnosis of radiolucent periapical lesions of the mandibular symphysis is presented.

Frontal intraosseous cryptic hemangioma presenting with supraorbital neuralgia

Primary intraosseous cranial hemangiomas are rare benign tumors comprising 0.2% of all osseous neoplasms. Symptomatic cranial cryptic hemangiomas are extremely rare. We report the case of a 43-year-old man with a cryptic hemangioma of the superior orbital rim. Radiological investigations revealed it to be an intraosseous cryptic mass which was totally excised and the supraorbital nerve was decompressed, relieving the patient of his symptoms. Histopathology showed features of an intraosseous hemangioma.

Giant intracranial and extracranial cavernous malformation. Case report

Massive enlargement of an extracerebral cavernous malformation and extension across tissue planes is very uncommon. The authors present the case of a 49-year-old woman with a giant cavernous malformation in the left frontotemporal area. It progressively enlarged during several decades, extended through the calvaria to the extradural space, and was surgically treated. The lesion may have originated in the soft tissue or the skull. The locations of cavernous malformations in various parts of the body are reviewed and their mechanisms of growth are discussed. Surgical excision is the treatment of choice.

Unusual frontal osteoma, mimicking a haemangioma

We report a patient with a frontal bone osteoma showing the classical findings of haemangioma. A craniectomy and total tumour excision was carried out.

The calvarium

The calvarium is a crucial structure that can manifest a great deal of pathology. The plain film remains the main imaging modality, although CT and MRI are becoming increasingly important. We discuss its anatomy, normal variants, congenital and developmental anomalies, hematologic disease, idiopathic disorders, neoplasms, metabolic disease, trauma, and the postoperative skull. Whenever possible, we emphasize CT and MRI.

Primary intraosseous orbital hemangioma: a case report and review of the literature

Primary intraosseous orbital hemangiomas are rare tumors. Only 25 cases have been reported in the literature. Very few of them have multiple orbital bone involvement. We report a case with extensive involvement of the orbital roof, the medial and lateral walls of the orbit, and the lesser and greater wings of the sphenoid, and describe a unilateral extradural frontotemporal approach to excise the tumor and decompress the right superior orbital fissure and both optic nerves. A brief clinical and radiological review of the literature is presented.
