Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occurred in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic fin...
PURPOSE To study the clinical and radiologic findings in 15 patients presenting with both developmental venous anomalies and cavernous angiomas and to determine which lesions caused the acute clinical symptoms. METHODS Lesions were infratentorial in 7 patients and supratentorial in 7 other patients. In one patient the developmental venous anomaly was infratentorial and the cavernous angioma s...
OBJECTIVE To report a rare case of unilateral cavernous sinus thrombosis caused by contralateral sphenoid sinusitis. CASE REPORT A 33-year-old female visited our hospital for severe, right-sided, temporal headache, chemosis, periorbital edema, and proptosis. These signs were associated with congested erythematous nasal mucosa with purulent discharge from the right superior nasal meatus. Contr...
PURPOSE The classic symptoms and signs of carotid cavernous sinus fistula or cavernous sinus dural arteriovenous fistula (AVF) consist of eye redness, exophthalmos, and gaze abnormality. The angiography findings typically consist of arteriovenous shunt at cavernous sinus with ophthalmic venous drainage with or without cortical venous reflux. In rare circumstances, the shunts are localized outsi...
hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).however, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. hereby, authors report a w...
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...
PURPOSE To investigate whether intracavernosal injection of short hairpin RNA for IGFBP-3 could improve erectile function in streptozotocin-induced diabetic rats. MATERIALS AND METHODS After 12 weeks of IGFBP-3 short hairpin RNA injection treatment, intracavernous pressure responses to electrical stimulation of cavernous nerves were evaluated. The expression of IGFBP-3 and IGF-1 at mRNA and p...
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, ...
hemangiomas of the sinonasal tract are rare, and because these lesions lack the typical signs or symptoms, they can be confused with other malignant conditions. we report a case of cavernous hemangioma of the maxillary sinus in a 68-year-old man that was completely resected by endoscopic sinus surgery. although computed tomography (ct) and magnetic resonance imaging (mri) showed several enhanci...
Hemangiomas are rare tumors in the calvarium and represent 2% of osseous calvarial lesions. Dynamic Tc-99m RBC blood pool scintigraphy has a high positive predictive value for cavernous hemangiomas of the liver. This scintigraphic technique can be used for identifying cavernous hemangiomas at other anatomic sites. We present a case in which a tagged RBC blood pool scan was used for further char...
