BACKGROUND Cavernous hemangioma is a frequent and the most common, primary, benign tumor of the orbit in adults. It is typically single and unilateral, considered not to recur after having been completely excised. Multiple orbital cavernous hemangiomas without signs of hemangiomatosis are rare. Multiple cavernous hemangiomas may recur after a complete excision and may exist with concurrent syst...

Using immunohistochemistry, we studied the origins and pathways of parasympathetic and sensory nerve fibers to the pial arteries in four squirrel monkeys. Following its application to the surface of the middle cerebral artery, the retrograde axonal tracer True Blue accumulated in parasympathetic neurons of the sphenopalatine ganglion and the internal carotid ganglion. The latter is strategicall...

The location of the original sites of the lesions was studied in 22 non-traumatic and 21 traumatic intracavernous carotid aneurysms in which the neck of the aneurysm was confirmed, and also in 23 traumatic carotid-cavernous fistulas in which the location of the fistula was identified. In the cavernous sinus, common sites of non-traumatic and traumatic carotid aneurysms as well as traumatic caro...

OBJECTIVE To describe the clinical and genetic findings in a family with multiple cases of cavernous hemangiomas. DESIGN Investigational clinical and genetic study in which 3 generations of a family consisting of 12 members were screened with magnetic resonance brain imaging, dilated ophthalmoscopic examination, and cutaneous survey coupled with linkage analysis to determine affected individu...

This report describes a series of patients for whom dural arteriovenous fistulae (DAVFs) of the cavernous sinus were successfully embolized using a percutaneous, transorbital technique to directly cannulate the cavernous sinus. A vascular access needle and catheter are percutaneously advanced along the inferolateral aspect of the orbit to access the cavernous sinus via the superior orbital fiss...

Adrenal cavernous hemangiomas are rare nonfunctioning benign tumors. This case report presents a patient with a huge nonfunctioning adrenal cavernous hemangioma presenting as an adrenal incidentaloma suspicious for adrenal myelolipoma. Although adrenal cavernous hemangiomas are rare, they should be considered as a part of the differential diagnosis of adrenal neoplasms. The proper treatment is ...

We report a case of hepatic cavernous hemangioma with computed tomographic findings of well demarcated nodular lesser attenuation foci within the main low attenuation mass on precontrast scans and non-enhancement of the foci even on the delayed contrast scans. These have been described as one of the atypical findings of cavernous hemangioma earlier in the literature. Surgery proved that scleros...

Forty seven cases of central nervous system cavernous angioma (21 males and 26 females) are described. The main clinical signs were epilepsy and brainstem syndromes. Digital subtraction intra-arterial angiography, when used, failed to reveal cavernoma. CT detected many of the lesions, but the most successful supplementary diagnostic procedure was MRI which produces highly characteristic images ...

Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival fistula. Clival dAVFs may have a variety of potential anatomical configurations but are defined by the involvement of the venous plexus just over...

Three patients with spontaneous dural carotid-cavernous fistulas were treated by using a combination of detachable coils and Onyx liquid embolic agent. Cavernous sinus was accessed via the superior ophthalmic vein or inferior petrous sinus approach. In all cases, a complete angiographic closure of the fistulas was achieved with full recovery from neuro-ophthalmologic symptoms. This report sugge...
