[Pleomorphic adenoma mimicking dacryoadenitis].

A 56-year-old female patient displayed an increased volume of her left lacrimal gland with pain and inflammation. On CT scan, a hyperdense lacrimal mass was found in the left lacrimal fossa. Observation was the first course, for no steroid therapy could be applied because of evolving digestive ulcers. After 9 months of observation, the gland was surgically removed en bloc through a wide anterolateral approach. Pathological analysis of the gland showed a pleomorphic adenoma. This case illustrates the advantage of a wide surgical approach in treating lacrimal gland tumors, in order to avoid or limit the risk of recurrence.

Suboccipital and cervical chordomas: radical resection with vertebral artery control.

OBJECT: Radical resection of chordomas seems to improve a patient's long-term prognosis. At the suboccipital and cervical levels, the vertebral artery (VA) is often considered as a limit in surgical possibilities. The authors report on the management of the VA in a series of 36 patients with chordomas located in the cervical region. METHODS: Over an 11-year period, 36 patients with chordomas located at the suboccipital (28 patients) or cervical (eight patients) level were treated in the authors' neurosurgical department. In 30 patients, the tumors extended laterally toward the VA and required surgical control of the VA. Sixteen of these 30 patients harbored primary tumor, whereas 14 were treated for recurrent disease. The VA was encased in the tumor in 23 patients, with stenosis in six cases. A balloon occlusion test was performed in seven patients and the VA was resected in four. Extensive resection, via a lateral approach on one (22 cases) or on both (eight cases) sides, did not cause any permanent postoperative deficits. In five patients a complementary approach was performed: posterolateral in one and transoral in four. Spinal fixation was performed via the lateral approach (eight cases) or via a complementary posterior approach (five cases). All but two patients underwent radiotherapy, including 10 who underwent proton-beam radiotherapy. CONCLUSIONS: Chordomas extending laterally to the VA can be radically resected via a lateral approach without causing significant morbidity. A complementary approach is often necessary. The best results are achieved in patients with primary compared with recurrent tumor.

Percutaneous jugular placement of ventriculo-atrial shunts using a split sheath. Technical note.

The percutaneous placement of ventriculo-atrial (V-A) shunts for treatment of hydrocephalus has been previously reported by several authors as a simplified procedure. However, this technique did not avoid the use of a distal connector between the outlet catheter and the atrial one, which may lead to a disconnection. A technique of percutaneous V-A shunt insertion using a split sheath is described and illustrated with a series of 22 patients. The use of a split sheath eliminates any distal connector thus avoiding the risk of shunt disconnection and reducing the operating time. The average operating time was 31 min. This rapid procedure allowed us to operate on two of our patients under local anaesthesia. The correct placement of the atrial catheter tip was performed under fluoroscopic control and always confirmed by postoperative radiographs. Two incidents of carotid artery puncture were controlled by simple local compression without further consequences. The mean follow-up time is one year. All the patients' clinical conditions improved. We are encouraged to use this V-A technique more frequently as a method of choice in the treatment of adult hydrocephalus or when the peritoneal cavity is inaccessible in children. The use of a split sheath is successful in reducing the operating time and avoiding the use of a distal connector.
