Primary intracranial extradural Burkitt-type lymphoma. A unique presentation with unilateral loss of vision in a child.

An unusual case of primary extranodal Burkitt's-type lymphoma of the frontal base dura and adjacent bone with intradural invasion is reported in a 5-year-old child who presented with unilateral loss of vision in the left eye. Tissue diagnosis was obtained through a craniotomy and the patient received radiotherapy plus intravenous and intrathecal chemotherapy. The tumor regression and improvement in vision was well documented by means of CT and visual evoked potential studies (VEP). A review of the literature on this exceptionally rare tumor is presented.

Extradural haematoma after continuous extradural anaesthesia.

We report a case of extradural haematoma occurring after extradural anaesthesia in an anticoagulated patient. The diagnosis was confirmed by magnetic resonance imaging and the haematoma was evacuated surgically. A search of the literature revealed only five previous reports of extradural haematoma in association with extradural anaesthesia.

Craniosynostosis: a review of 143 surgically-treated cases.

In this study, 143 cases of craniosynostosis are presented. There were 109 males and 34 females. The major complaints were skull deformity (92 patients), proptosis (38 patients) and microcephalus (32 patients). Neurological examination revealed the presence of optic atrophy in 24 patients and papilledema in 20 patients. Seventy-four patients (53%) had three or more suture closures, with the sagittal suture being the most commonly involved (20% of patients). All patients underwent surgery. Suture removal was performed in 131 patients (91.7%), suture removal plus orbital decompression in 34 (23.8%), and linear craniectomy plus wrapping in 12 (8.3%). The reoperation rate was 6.2 percent. During the follow-up period, preoperative papilledema and proptosis improved in 88.2 and 78.9 percent of patients, respectively. Skull deformity disappeared in 46.9 percent of patients, but remained unchanged in 16.6 percent.

Nonsuture closure of arterial defect by vein graft using isobutyl-2-cyanoacrylate as a tissue adhesive.

Nonsuture repair of intracranial blood vessel is still a challenging issue in neurosurgery. In this experimental study isobutyl-2-cyanoacrylate was used for nonsuture repairing of carotid artery to observe its histotoxicity. Isobutyl-2-cyanoacrylate was dropped over the edge of defect on carotid artery of rat under the surgical microscope and jugular vein was placed to cover the defect. Rats were divided in 6 group according to postoperative survival period (2, 5, 7, 14, 21, 28 days respectively). The carotid arteries were patent of all rats according to angiography and autopsy specimen. Histopathological results showed that: the changes are mainly inflammatory respons +, there was no necrotic tissue at any time the healing progress and no significant differences in the vein graft. Therefore isobutyl-2-cyanoacrylate is considered helpful and safe adhesive material for the nonsuture repair of blood vessel.
