“…In advanced cases, proptosis, blepharoptosis, diplopia, and visual loss may ensue as tumors expand into the orbital cavity 11617. Cavernous hemangiomas of the skull base are exceptionally rare, and only two have been reported to arise from the clivus 1819…”

“…Typically, these lesions appear as well-circumscribed, expansive areas of rarefaction owing to resorption of trabeculae by enlarged vascular channels. This leads to a honeycomb or polka-dotted pattern seen on CT, representing coarse trabeculae seen in axial cuts 11819. This is particularly apparent in vertebral hemangiomas but is not well appreciated in calvarial hemangiomas.…”

“…Hence, on T1-weighted sequences, smaller lesions or those with more fatty content tend to have higher signal intensity. On T2-weighted sequences, areas with slow venous flow or blood pooling have increased signal intensity 11819. Generally, though, intraosseous hemangiomas have heterogeneous signal in both T1- and T2-weighted sequences, and CT scan is more useful for operative planning.…”

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.

“…Our patient showed symptoms related to both locations. Including our case, the cavernous variant of the hemangioma was observed in 14 out of 18 cases (78%) of clival and petrous bone hemangiomas, whereas capillary variant was reported in four out of 18 cases (22%) …”

Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH) is considered a non‐neoplastic lesion. It is probably an unusual exaggerated reorganization of a thrombus. IPEH may be present as a secondary lesion in hemangiomas. Symptomatic osseous hemangiomas are rare tumors. Few cases of clival and petrous bone hemangiomas have been described. None of them shows secondary IPEH. So far, there are only four reported cases of cranial bone IPEHs in the literature, two in the skull, one in the clivus and one in the petrous apex. The aim of this study is to report an additional case of osseous hemangioma with secondary IPEH of the petroclival region. We review the literature and describe the main clinical features of IPEHs and hemangiomas of the clivus and the petrous bone. Additionally, we report an unusual histological feature observed in our case of IPEH, the presence of psammoma body‐like structures. This feature has been rarely mentioned previously in IPEH. We consider that IPEH should be included in the lesions that may present psammoma bodies to avoid misdiagnosing it as a tumor that commonly shows psammoma bodies, such as intraosseous meningioma or, less frequently, metastasis of thyroid or ovarian carcinoma.

“…Radiologically these lesions are well circumscribed, expansile with areas of rarefaction owing to osteoblastic remodeling of trabecular bone following osteoclastic activity of the tumor resulting in a typical sunburst appearance on X-ray or a honeycomb or polka-dot appearance on axial CT scan [2,11,16]. On MRI intraosseous hemangiomas have heterogeneous signal on both T1- and T2-weighted sequence depending basically on the amount of venous blood, content of red marrow and fatty marrow [16]. However, of note is that smaller calvarial hemangiomas may not exhibit all the classic radiological signs except for the rarefaction of the bone, and the diagnosis may be made only after histopathology [17].…”
