Cavernous sinus angioleiomyoma (ALM) is extremely rare. Only three cases have been reported to be cavernous sinus ALM, and very few reports described characteristic findings for intracranial ALMs in detail. We report a new case of cavernous sinus ALM, with detailed information on the clinical presentation, radiology, pathology, and surgical approach. A 52-year-old woman had a 6-month history of...

Radiographic signs of cavernous sinus thrombosis were found in eight consecutive patients with an angiographic diagnosis of carotid-cavernous sinus fistula; six were of the dural type and the ninth case was of a shunt from a cerebral hemisphere vascular malformation. Diagnostic features consisted of filling defects within the cavernous sinus and its tributaries, an abnormal shape of the caverno...

abstract we reported and analyzed an unusual case of npc (nasopharyngeal carcinoma) where the patient had initial clinical features of cavernous sinus involvement followed by trigeminal neuralgia and middle ear dysfunction. in the present case, the initial involvement of the cavernous sinus resulted in the left sided third nerve involvement. later on, the extension of the tumor in and around th...

The classical imaging gold-standard for this diagnosis is the presence of tumor lateral to the carotid artery. Seventeen patients with pituitary macroadenomas with intraoperative confirmation of cavernous sinus invasion were studied with MRI. Only 8 patients had tumor lateral to the carotid artery; 13 had tumor within the carotid syphon and all lacked the ring enhancement of the medial wall of ...

The ability of high-resolution MR imaging (1.5 T) to detect invasion of the cavernous sinuses by pituitary adenoma was determined through a retrospective review of 74 patients. These patients were divided into three groups: 25 normal subjects, 24 subjects with invasive pituitary adenomas, and 25 subjects with noninvasive pituitary adenomas. A fourth group of 30 patients, who subsequently underw...

Arteriovenous fistulae of the cavernous sinus are rare and difficult to diagnose. They are classified into dural cavernous sinus fistulae or direct carotid-cavernous fistulae. Despite the similarity of symptoms between both types, a precise diagnosis is essential since the treatment is specific for each type of fistula. Imaging findings are remarkably similar in both dural cavernous sinus fistu...

This case of traumatic carotid-cavernous fistula was caused by rupture of a peculiar ipsilateral intracavernous anastomosis between the accessory meningeal artery and the redundant deep recurrent ophthalmic artery. In the opposite cavernous sinus there was an obvious anastomosis between the accessory meningeal artery and the ophthalmic artery, probably located in the lateral part of the caverno...

OBJECT Lesions of the cavernous sinus remain a technical challenge. The most common surgical approaches involve some variation of the standard frontotemporal craniotomy. Here, the authors describe a surgical approach to access the cavernous sinus that involves the removal of the lateral orbital wall. METHODS To achieve exposure of the cavernous sinus, a lateral canthal incision is performed, ...

Evaluation of over 255 patients with sellar and parasellar lesions allowed study of the computed tomographic (CT) appearance of the cavernous sinus. Optimal visualization of the cavernous sinus was obtained with continuous contrast enhancement of both axial and coronal tomograms. The coronal projection provided imaging of cranial nerves within the cavernous sinus. The intracavernous carotid art...

Unilateral carotid cavernous fistula presents with ipsilateral ocular findings. Bilateral presentation is only seen in bilateral fistulas, usually associated with indirect (dural) carotid cavernous fistulas. Direct carotid cavernous fistulas are an abnormal communication between the internal carotid artery and the cavernous sinus. They typically begin with a traumatic disruption in the artery w...
