Hemangioma intraóseo primario de la órbita: a propósito de dos casos

Mandibular Fracture as First Sign of an Occult Intraosseous Hemangioma

Intraosseous hemangioma (IH) in the maxillofacial area is a very uncommon neoplasm. Here, the authors show an exceptional case not previously reported in the literature of a 65-year-old man who presented with a pathological mandibular fracture following a facial trauma that was the first sign of an occult cavernous IH. Complete excision of the tumor in the mandibular ramus reduced the risk of severe bleeding and prevented long-term recurrence, whereas immobilization of the fracture obtained an excellent functional result. This clinical report highlights the possibility that a previously unknown primary IH may debut as a pathological fracture and the importance of differential diagnosis in this location.

Posttraumatic cavernous hemangioma of the skull

A 59-year-old man presented with a slowly enlarging mass in the lateral orbital rim of the left eye for 1 year. He also reported a history of crania defect in the left front bone (6 years earlier) which was confirmed on the former computed tomographic (CT) scan. On examination, the solid mass lesion located in the left frontal extends to the lateral orbital rim of the left eye. CT scan showed a mass with poorly defined margins, which invaded the neighboring tissue and nearly damaged the bone, and located on the exact site of the preceding crania defect. Complete resection was performed, and the clinical diagnosis of cavernous hemangioma was confirmed on histopathologic examination. Skull cavernous hemangiomas are rare tumors for which the origin is not yet clear. We report a case in which the intraosseous hemangiomas developed at the same site of the preceding crania defect.
