A case of chronic epidural and epicranial pneumocephalus in a 31-year-old man with a history of head trauma and progressive development of a soft tissue mass in the occipital region is reported. Its hypothetical pathogenesis and pathophysiology are discussed.
A rare case of intracerebral chondroma in a 45 years old man with a long history of headache and recent epilepsy is presented. Microscopic examination of the resected tumor revealed that it was chondroma.

The results of a retrospective analysis of a series of 73 polytraumatised patients with severe head injuries are presented. The neurological outcome has been less favourable in cases with early osteosynthesis of peripheral fractures compared to cases in which such operations had been delayed. Therefore it seems advisable to postpone the non-vital operative treatment of osteoarticular lesions until stabilisation of the cerebral and vegetative situation.

Cerebellar abscess induced by a contiguous dermal sinus is a rare event. In a large series of acute posterior fossa abscedation, otogenic suppuration is the cause in 93% of the cases, while hematogenous infection is infrequent, probably because of the relatively weak bloodflow in this part of the central nervous system. The authors present an occipital dermal sinus and dermoid cyst revealed by a cerebellar abscess. The literature is reviewed briefly, treatment and prophylactic measures are discussed.
After a lower hemi-cervical spinal cord injury, a patient presented with a left hemiplegia and on the same side a unilateral chest wall paradoxical motion mimicking a flail chest. X-rays demonstrated a left hemilateral C6 injury but no rib fractures. We demonstrated that the paradoxical motion was due to the action of the diaphragm acting on the rib cage with intercostal respiratory paralysis on the side of hemiplegia.
Two cases with bilateral traumatic oculomotor palsy are presented. The clinical signs, diagnosis criteria, and mechanisms of injury are discussed with a special emphasis on the absence of early reliable prognosis factors. The possibility of recovery depends on the anatomic lesion and not on the ophthalmologic findings in the acute phase.
A case of occult intrasacral meningocele is reported and the diagnostic reliability of conventional roentgenography, myelography and CT for the management of this rare lesions are evaluated. Probably, CT with the use of an intrathecal contrast agent could yield the most complete information about the precise nature of this cystic congenital dysraphism.
In a case of brain death, a Clostridium sordellii and Escherichia coli septicaemia--of probable gastrointestinal origin--developed and was associated with a diffuse clostridial myositis. Factors responsible for the initiation and development of this unusual clostridial infection are discussed.
An unusual case of traumatic asphyxia with cerebral and spinal cord symptoms is presented. A survey of the literature indicates that a primary cord lesion is very rare as a consequence of such a trauma. The possible pathogenetic mechanisms of these neurological manifestations are discussed.

The purpose of this paper is to define the nature and the frequency of post-lumbar sympathectomy complications and to reappreciate their importance in the evaluation of operative indication. The non specific miscellaneous complications are no more frequent than after any other lombotomy. The specific complications occur in less than 10%; they are almost always transient. Prolonged paralytic ileus is related to post-operative hematoma in retroperitoneal space. Ejaculation disturbances are produced either by bilateral resection of one of the two first lumbar ganglian or by section of the intermesenteric plexus, the presacral nerves or the hypogastric nerves during associated dissection of the aortic bifurcaiton. Late neuralgia is probably induced by retroperitoneal hematoma; its size increases gradually during the postoperative period by transference of tissue fluids. In conclusion, the morbidity and the morbidity rates of lumbar sympathectomy are remarkably low; these are not arguments against the lumbar sympathectomy.
