Arterialized blood flow in the cavernous sinus may result from carotid-cavernous fistula or dural venous fistula. We encountered an unusual case of arterialized blood flow in the cavernous sinus on MR angiography resulting from arterialized retrograde venous flow in the internal jugular vein. This abnormal flow originated from an upper extremity dialysis arteriovenous fistula in the presence of...

A 40-year-old male with left-sided headaches, ptosis, proptosis and extra-ocular muscle paralysis developed right-sided headaches, proptosis, chemosis, diplopia, extra-ocular muscle paralysis and trigeminal sensory loss. An enhancing left orbital, intrasellar and parasellar cavernous nodule on magnetic resonance imaging progressed into a right cavernous sinus and orbital apex soft tissue mass. ...

Multifocal cavernous haemangioma of the skull presenting as lytic lesions are a rare entity with only a few case reports till date. Haemangioma are benign lesions, well known to occur in the spine and are of the capillary type whereas the haemangioma that occur in the skull are of the cavernous type and are usually solitary. Here we present a case of multifocal cavernous haemangioma of the skul...

We present a family afflicted by both extensive cerebral cavernous malformations (CCMs) and spinal cord cavernous malformations (SCCMs). These may be inherited in an autosomal dominant pattern or occur sporadically. The presentation varies and may include a multitude of clinical symptoms separated in time and space. Cavernous malformations should be considered in the differential diagnosis of s...

Carotid-cavernous fistulas (CCF) are abnormal communications between the internal carotid artery and the cavernous sinus. Traumatic carotid-cavernous fistulae are rare potential complications of craniofacial trauma. Typical findings of CCF are proptosis, chemosis, headache, oculomotor or abducens nerve palsy, trigeminal pain and pulsating bruit over the temporal skull and the bulb. CCF are repo...

An 11-month-old female patient presented with symptoms of orbital venous congestion. A CT scan showed enlarged superior ophthalmic vein and cavernous sinus on the symptomatic side. Catheter angiography confirmed a direct carotid-cavernous fistula with intra- and extracranial venous drainage. Successful coil embolization of the fistula was performed with resolution of the infant's symptoms and r...

PURPOSE To present the results of our treatment of dural cavernous sinus fistulas with surgical exposure of the superior ophthalmic vein (SOV), retrograde venous catheterization, and coil embolization of the cavernous sinus. METHODS Twelve patients with dural cavernous sinus fistulas were treated via a retrograde transvenous SOV approach in our hospital during a 3-year period. All patients ha...

BACKGROUND The aim of this study was to determine if shRNA constructs targeting insulin-like growth factor binding protein-3 can rehabilitate decreased serum testosterone concentrations in streptozotocin-induced diabetic rats. MATERIAL/METHODS After 12 weeks of intracavernous administration of IGFBP-3 shRNA, intracavernous pressure responses to electrical stimulation of cavernous nerves were ...

BACKGROUND Only 2 cases of abducens nerve schwannoma solely inside the cavernous sinus have been reported. In both cases, abducens nerve palsy remained after operation. We report the first case of abducens nerve schwannoma inside the cavernous sinus proper with postoperative recovery from abducens nerve palsy. CASE DESCRIPTION The patient was a 47-year-old female who developed left abducens a...

background & importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. we report a case of the spinal intradural cavernous angiomas of the lumbar spine. case presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. ...
