[Hemangioblastoma of the cauda equina].

Hemangioblastomas are dysontogenetic tumors of the central nervous system. They occur as single tumors or multiple. Hereditary and sporadic cases are known. The most frequent localisations are the retina and cerebellum but they can be localized at any site of the neuraxis. In a 37 year old male patient a solitary hemangioblastoma of the cauda equina was demonstrated by myelography and totally removed by laminectomy. In the literature 17 cases of isolated hemangioblastomas of the cauda equina are described. A further 16 cases of were observed within a Lindau-complex, 10 of which remained without symptoms. For diagnosis of the type of tumor a myelography is rarely sufficient. The only successful therapeutic measure is total surgical removal.

[Spontaneous intraorbital hematoma].

A case of spontaneous intraorbital Haematoma is reported. A girl aged 13 years developed an acute unilateral Exophthalmos on the right side with disturbances of eye-motion, choked disc and nearly complete amaurosis within 3 days after onset. The etiology of the bleeding remains unknown. The diagnosis of orbital haematoma was made by the clinical picture and the computerized axial tomography (CAT) findings. Through a lateral orbitotomy was the extraperiorbital haematoma evacuated, with a complete recovery within two weeks. Twenty-two cases of the literature are reviewed. The possible aetiologic causes are discussed: haemorrhagic diatheses, arterial, vasomotoric and toxic diseases, the congestive and traumatic causes mentioned. The clinical picture and diagnositc procedures, especially the CAT, are reviewed. The surgical treatment with stress on the lateral orbitotomy is discussed.

[Parinaud's syndrome with false localization signs in supra-and infratentorial space-occupying lesions].

Parinaud's syndromes may occur in infra- and supratentorial space-occupying lesions, but very careful differential diagnosis must be made in those cases. Occurring peripheral signs are due to brain mass displacements caused by transtentorial brain herniae. The prognosis is relatively good if the space-occupying lesions may be entirely or at least sufficiently removed. Five corresponding cases are described and clinical, neuroradiological and surgical findings discussed.

[Clinical observations on hydrocephalus with special regard to the posttraumatic malresorptive form (author's transl)].

100 cases of Spitz-Holter shunts performed for hydrocephalus over a period of 3 years were analyzed; 17 of these were of posttraumatic origin and are discussed in regard to pathogenesis, clinical symptoms, diagnostic methods, and therapy. Half of these 17 had severe traffic accidents. The rapidity and degree of ventricular dilatation were positively correlated with the duration of unconsciousness. When the unconsciousness had lasted more than 10 days hydrocephalus was recognized early, and the shunt was performed on an average 2 months after the trauma. Two thirds of the patients improved after the shunt operation. Pathogenetically we believe the important factors in the acute stages are increased CSF pressure, disturbed CSF dynamics, brain swelling and vascular circulation disorder; in the chronic stages, parenchymous atrophy. The following 3 types of posttraumatic hydrocephalus were differentiated on the basis of the clinical features: --symmetrical communicating internal hydrocephalus with malresorption, especially after subarachnoid hemorrhage, --communicating internal hydrocephalus alone, or in combination with external hydrocephalus resulting from atrophy, --internal occlusive hydrocephalus after trauma. The following posttraumatic clinical features were found to be indications that hydrocephalus may be present: in the acute stages inadequately long symptom resolution considering the severity of the trauma, secondary changes for the worse, an apallic syndrome which does not improve; in late stages, the presence of an Adams-Hakim syndrome charaterized by dementia, a spastic gait and loss of sphincter control. The most successful diagnostic methods were found to be pneumencephalography with 24 and 48 h delayed exposures, cisternoscintigraphy and continuous intracranial pressure monitoring in combination with the spinal infusion test. The most important intracranial shunting procedures and the indications for shunting are discussed.
