Introduction:
Haemangiomas of the temporal bone are rare tumours and haemangiomas involving the middle ear are even rarer. The exceptional nature of these lesions makes their management particularly complicated.
Case Report:
The authors report the case of a 16-year-old girl, who presented with an osteolytic lesion of the left petrous temporal bone that proved to be a haemangioma with extension to the middle ear, causing conductive hearing loss.
Discussion:
Surgical biopsy is essential to establish the diagnosis of haemangioma because imaging alone only rarely provides a definitive diagnosis. Surgery is the reference treatment to prevent recurrence. Arteriography is an essential part of the preoperative assessment in order to limit the risk of bleeding.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
