In this study, we present an eight-year-old patient with intraosseous hemangioma in the right humerus diaphysis. The humerus diaphysis is an unusual localization for hemangioma. To our knowledge, this is the first case of intraosseous hemangioma in the humerus diaphysis in a pediatric patient. Treatment of intraosseous hemangiomas is controversial; options range from untreated follow-up to en-bloc resection. Intralesional curettage and grafting with cortico-cancellous allograft were performed in this case. Around 22 months postoperatively, she showed full shoulder and elbow function and there was no evidence of local recurrence or metastasis.

Rationale: Multifocal intraosseous hemangioma, which affects multiple body parts, is rare. The selection of appropriate lesion sites for biopsy and effective treatment in multifocal intraosseous hemangioma is challenging. Here, we report a case of multifocal intraosseous hemangioma. Patient concerns: A 49-year-old woman was admitted to our department with a chief complaint of aggravated lumber pain for 10 days. Diagnoses: Radiographic imaging revealed lesions involving the bilateral ribs, lumbar vertebrae, ilium, pubis, and proximal femur. Open biopsy in the ilium established the pathological diagnosis of intraosseous hemangioma. Interventions: For the symptomatic lumbar spine, the patient selected radiotherapy as the initial treatment. Outcomes: As of the one-year follow-up, no symptoms of recurrence have been observed. Lessons: This rare case demonstrates the importance of the selection of the appropriate lesion to confirm the diagnosis and effective treatment for patients with multifocal disease. Radiotherapy plays an important role in the treatment of patients with symptomatic vertebral hemangiomas without neurologic deficits.

The present study reports a rare case of large capillary hemangioma of the temporal bone with a dural tail sign. A 57-year-old female presented with pulsatile tinnitus and episodic vertigo associated with a ten-year history of an intermittent faint headache. Magnetic resonance imaging revealed a mass in the right petrous bone, which was hypointense on T1-weighted images and heterogeneously hyperintense on T2-weighted images, and showed a dural tail sign following gadolinium administration. Pre-operatively, this tumor was believed to be a meningioma. During surgery, the vascular tumor was removed by a modified pterional approach. A histopathological examination indicated that the tumor was a capillary hemangioma. Although intraosseous capillary hemangiomas are rare, they most frequently affect the temporal bone. Hemangiomas of the temporal bone may mimic other more common basal tumors. The diagnosis is most often made during surgical resection. The dural tail sign is not specific for meningioma, as it also occurs in other intracranial or extracranial tumors. The treatment of intratemporal hemangiomas is complete surgical excision, with radiotherapy used for unresectable lesions. To the best of our knowledge, the present study is the fourth case of intraosseous intracranial capillary hemangioma, but the largest intratemporal hemangioma to be reported in the literature to date.

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.

Intraosseous hemangiomas are benign vascular malformations which are extremely rare in the maxilla, but have been reported in the mandible, zygoma and orbital region. A 12 years old female presented to the oral and maxillofacial department with an ectopically positioned upper left canine in her zygomatic bone and buccal alveolar expansion between the upper left lateral incisor and upper left first premolar. This case shows the unusual presentation of an intraosseous hemangioma associated with an ectopically migrated upper left canine tooth. It is possible that this lesion caused migration of the tooth. The clinician should be aware of the possibility of this lesion for bony expansile lesions and the importance of radiographic examination in patients who present with delayed eruption of canine teeth.

Intraosseous cavernomas are very rare benign lesions representing less than 1% of all skeletal tumors and most frequently observed in vertebrae and head and neck bones. Solitary hemangiomas of the hand bones are exceptionally rare. We report a case of this neoplasm in the distal epiphysis of the third metacarpal bone in a 68-year-old man, along with the clinicopathological findings. The differential diagnosis and a review of the literature are discussed.

Intraosseous vascular lesions are rare conditions, comprising only 0.5% to 1% of all intraosseous tumors. They present with variable and atypical radiographic appearances. Because of this variation, no pathognomonic sign exists that can be used to make a definite clinical diagnosis of these tumors. But, early diagnosis of central hemangioma is essential for preventing uncontrollable hemorrhage and even death during biopsy or surgery. The purpose of this article is to stress on the importance of radiology in the timely diagnosis of such lesions, which can prevent the disaster not only to the patient but also to oral surgeon in legal and professional aspects.

Angiomatosis is a complex vascular malformation of infancy and childhood consisting of proliferating blood vessels with accompanying mature fat, fibrous tissue, lymphatic′s and nerves, which may involve skin, subcutaneous tissue, skeletal muscle and occasionally bone. It is extremely rare and benign, but a clinically extensive vascular lesion of soft-tissue, which usually becomes symptomatic during childhood or adolescence. We report a rare case of massive juvenile angiomatosis of maxilla and mandible in a 15-year-old male patient.
