Endovascular treatment in an unusual case of direct carotid cavernous fistula.

We describe a unique and unusual case of post-traumatic direct carotid cavernous fistula (CCF) with occluded proximal internal carotid artery and CCF filling from the contralateral side with retrograde cortical venous reflux. A male patient presented with intracranial haemorrhage due to cortical venous reflux. He was treated endovascularly through a contralateral approach by coiling the cavernous sinus and occluding the distal internal carotid artery at the fistulous site with glue.

Two patients with intracavernous haemangiopericytoma.

Haemangiopericytomas are relatively uncommon intracranial lesions making up less than 2.5% of all intracranial meningiomas. Their location in the cavernous sinus is extremely rare.

Giant interdural teratoma of the cavernous sinus.

A 27-year-old man presented with a 2-month history of retro-orbital pain and a 2-week history of progressive ptosis and diplopia. Neurological examination revealed left partial third, fourth and sixth cranial nerve paresis. Imaging revealed a large middle fossa lesion with heterogeneous signal intensity.

Glioblastoma multiforme of the conus medullaris with holocordal spread.

Glioblastoma multiforme of the conus medullaris is rare. It spreads both locally to contiguous structures and also by cerebrospinal seeding. The disease is aggressive and the ultimate prognosis is dismal.

Interdural cavernous sinus epidermoid cyst.

We report a patient with an uncommon interdural epidermoid tumor, located within the confines of dural layers of the lateral wall of the cavernous sinus. The tumor was resected by a basal subtemporal extradural-interdural approach. Following the surgery, the 45-year-old female patient recovered completely from her symptoms of atypical neuralgic facial pains.

Fourth ventricle arachnoid cyst.

We report four patients with fourth ventricle arachnoid cysts. There were two males and two females and the ages ranged from 18 months to 52 years (average 21 years). All patients presented with symptoms of raised intracranial pressure.

Unilateral atlantal lateral mass hypertrophy. Report of four cases.

The authors report the cases of four patients in whom they diagnosed an extremely rare and hitherto unreported clinical condition-unilateral hypertrophy of the C-1 lateral mass causing symptomatic cord compression. All patients presented with long-standing torticollis and progressive myelopathy. Three patients underwent posterior decompressive surgery and one underwent resection of the part of the lateral mass invading into the spinal canal and subsequent atlantoaxial plate and screw fixation.
