Two cases of surgically verified optochiasmatic arachnoiditis have been reported. In both patients, there was a more or less remote history of eye exposure to some form of radiant energy, together with other possible etiologic factors. The possible respective roles of these factors are discussed.

Spontaneous ("erosive") cerebrospinal rhinorrhea, with pneumococcal meningitis from anterior optic glioma. Case report.

A 6-year-old girl, operated upon for an optic nerve astrocytoma (resection limited to the intraorbital portion of the nerve), developed 3 years later symptoms and signs of chiasmatic invasion. Nine years after surgery (1980), she suffered from pneumococcal meningitis, due to cerebrospinal rhinorrhea that had been present in the last few years. A repeated neuroradiological investigation showed the site of the fistula and cerebral ventricles of normal size. The case is argued for bulb-to-chiasm resection of an optic nerve glioma: a spontaneous cerebrospinal rhinorrhea with its potential dangers of meningitis seems to be one more complication of a limited resection of these tumors. It is felt that this is an unusual instance of spontaneous rhinorrhea from direct tumoral erosion. The diagnostic value of metrizamide cisternography for the assessment of presence and site of the fistulous leak is confirmed.

Cervical rib syndrome: a neurosurgical experience with a series of 38 cases.

A series of 38 patients with thoracic outlet syndrome caused by a cervical rib is reviewed after a postoperative follow-up period of 3 to 24 years. The outcome of the operation (anterior scalenotomy and partial to subtotal removal of the cervical rib) is not considered wholly satisfactory; three causes for this were identified: excessive duration of symptoms (mean almost 6 years), insufficient patient work-up and inadequacy of the incomplete removal of the cervical rib. In the presence of a cervical rib, other possible causes of compression of the neurovascular supply to the upper limb should always be considered.
