Contralateral trigeminal neuralgia as a false localizing sign in intracranial tumors.

Three cases of contralateral trigeminal neuralgia as a false localizing sign in intracranial tumors are reported. In each patient (meningioma, 2 cases; cholesteatoma, 1 case) the tumor was asymptomatic, so that intracranial tumor had not been suspected preoperatively. In all cases, tumors were large and firm. The tumor was supratentorial in two cases. In one case, a cortically mediated mechanism may have caused the neuralgia, whereas in the remaining two cases distortion and displacement of the brain stem and compression of the contralateral Meckel's cave would explain the trigeminal nerve signs.

Craniopharyngioma of the third ventricle.

A woman, aged 33 years, presented with headache, drowsiness, and attacks of loss of consciousness with incontinence, during the eight months previous to admission. A CT scan showed a round cystic mass in the third ventricle which was interpreted as a colloid cyst. A myodil ventriculogramm showed the anterior part of the third ventricle completely occupied by tumour. Eleven months later, because of worsening of symptoms, a new scan was carried out, and the presence of an intraventricular tumour in the anterior part of the third ventricle was confirmed. The patient died four months later. The histological diagnosis of the previous biopsy, as well as the post mortem examination, showed a craniopharyngioma of the third ventricle. There was no macroscopic or histological involvement of the pituitary gland by the tumour.

[Hemangioblastoma of the spinal cord. A case with a probably single lesion (author's transl)].

A 43 year-old woman was admitted after 2 years of progressive disturbances of deep sensation mainly in her lower limbs. Examination led to the diagnosis of a tumor of the cervical spinal cord. The tumor--partially cystic--was attached to the posterior third of the spinal cord. At its level several varicosities of the pia were present accounting for the myelographic picture as well as for the albumino-cytologic dissociation in the CSF. Pathological examination showed a hemangioblastoma. After a review of the literature, this case of hemangioblastoma of the spinal cord appears to have special features because of its likely single location in the spinal cord in a patient without any familial history of phacomatosis or of von Hippel-Lindau's disease. No other lesion could be clinically suspected in the spinal cord. The post-operative evolution was satisfactory.

[Chemonucleolysis. Peridural anesthesia versus general anesthesia].

A prospective comparative study was carried out between two anesthetic techniques for chemonucleolysis. Patients were divided into 2 groups of 50 patients each. Group A were submitted to general anesthesia and group B to epidural anesthesia with 0.5% bupivacaine, 2% mepivacaine and buprenorphine. Group B was divided into 2 subgroups: in B1, buprenorphine was administered with the local anesthetics, while in B2 buprenorphine was administered postoperatively when pain appeared. Postoperative pain and side effects like anaphylaxis were evaluated. No anaphylactic reactions occurred. Severe lumbar pain appeared in 22% of patients in group A in spite of systematic analgesics, while group B lumbalgia was not severe in any case. Patients in subgroup B1 did not have pain during the 24 first hours and 47.8% of patients in subgroup B2 needed in most of the cases only a dose of buprenorphine. We conclude that epidural anesthesia is a good technique in chemonucleolysis and that the association bupivacaine, mepivacaine and buprenorphine provides a good postoperative pain relief.
