The diagnosis of a large cavernous malformation may be challenging because its imaging appearance is var iable . Here we reported a 22-year-old man with a large mass in left side temporal lobe. Computed tomography show...

OBJECTIVE The recent limitations of working hours for neurosurgical trainees carry the risk of decreasing the amount of microsurgical experience. In the absence of enough surgical exposure to some pathological states, an alternative option of a more continuous source of tactile and visual experience that simulates the real-life state is needed. To help with this problem, we established a cavern...

Dumbbell-shaped spinal extradural cavernous hemangioma is rare. The differential diagnosis of dumbbell-shaped spinal tumors based on magnetic resonance imaging includes schwannoma and lymphoma. Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic d...

We report experience with 11 patients misdiagnosed for years, on the basis of computed tomography (CT) and angiography, as harbouring brainstem tumours in whom magnetic resonance imaging (MRI) demonstrated cavernous angiomas. Seven had undergone external irradiation, 2 had a ventriculo-peritoneal shunt, 2 developed aseptic femur necrosis following corticosteroid treatment, 1 had undergone a bio...

The complete resection of intracavernous sinus dermoid cysts is very difficult due to tumor tissue adherence to important anatomical structures such as the internal carotid artery (ICA), cavernous sinus, and cranial nerves. As residual dermoid cyst tissue sometimes induces symptoms and repeat surgery may be required after cyst recurrence, minimal invasiveness is an important consideration when ...

Metastasis to the cavernous sinus from head and neck cancer is uncommon and has been previously reported by a few authors. It is usually a late manifestation of the primary tumor and may be the first evidence of a widespread dissemination of the disease. Main clinical findings are those related with involvement of cranial nerves III to VI as they pass through the cavernous sinus. Although diagn...

PURPOSE To report a case of spontaneous direct carotid-cavernous fistula causing abrupt loss of vision. CASE REPORT A 50-year-old woman with systemic hypertension but no history of ocular disease developed sudden proptosis, frozen eye, subconjunctival hemorrhage and loss of vision in her left eye over 2 hours. Imaging studies revealed a direct carotid-cavernous fistula. Management for high in...

Cavernous hemangioma of the lung synonymous with arteriovenous fistula or aneurysm of the lung is generally considered to be a congenital abnormality. According to Lindskog and Liebow,1 at least 60 cases are in the literature. Roentgenologically, cavernous hemangioma has the appearance of a lobular shadow of increased density continuous with hilar vascular shadows. Clinically it is usually asso...

Background: The cavernous sinus (CS) is a complex anatomical structure that poses significant challenges to neurosurgeons performing surgical interventions in this region. A comprehensive understanding of the anatomy CS, including its relevant landmarks and structures, crucial for successful outcomes. Objective: This review aimed provide overview as well approaches neurosurgeons. Methods: liter...

Hemangiomas are common, benign tumors which arise from the proliferation of endothelial cells surrounding blood-filled cavities. Cavernous hemangioma nasal cavity is a rare clinical entity but it should be considered in differential diagnosis nasopharyngeal mass and cases with epistaxis. This lesion usually found on lateral wall more common elderly no sex preponderance. We present case cavernou...
