Post-traumatic cerebral air embolism. Case report.

A case of post-traumatic cerebral air embolism is presented. In the chest-X-radiography fractures of many ribs and hemo-pneumothorax were visible on the right side associated with intra-alveolar, interstitial hemorrhages and mediastinal emphysema. At the end of a CT scan of the head appeared features of arterial air embolism. The patient was diagnosed as brain dead and cardiac arrest occurred one hour after.

Cerebral cavernous angioma. Diagnostic considerations.

Eighteen cases of cerebral cavernous angiomas are reported, and their histopathological, clinical and radiological features are reviewed. MR complements TC in characterizing cavernomas and in distinguishing them from similar-appearing lesions. However, when such lesions are seen with atypical features, discrimination from hemorrhagic tumors remains problematic. More malignant lesions present, on MRI, a much larger area of abnormality and make themselves obvious in a shorter period. Gadolinium administration may allow a more specific interpretation of small lesions.

Herniated disk in adolescents.

Twenty-one patients (9 female and 12 male) aged from 13 to 22 years were observed for lumbago and lumbo-sciatica caused by a discopathy which was subsequently confirmed by radiology and surgery. None of these patients had a history of trauma. It must be underlined that the painful symptoms exhibited and the young age of the patients suggest such pathologies as infections, tumours or malformations, but the possibility of discopathy must always be considered. It is also interesting to note the differences observed in symptomatology between adults and adolescents and to consider the various pathogenetic factors which might cause discopathy in adolescents while it was until now believed to be reserved to adults.

Surgical indications for intracranial arachnoid cysts.

Diagnostic work-up and management of intracranial arachnoid cysts are still controversial. The authors have standardized a therapeutic protocol based on the information derived from CSF contrast flow studies. The report concerns 16 cases of intracranial arachnoid cysts treated according to their protocol.

Cavernous sinus meningiomas.

Analysing 12 cases of cavernous sinus meningiomas the authors conclude that: the clinical history is characteristic; CT scan has proved to be more sensitive than carotid angiography in detecting small lesions. However in large lesions the vascular supply pattern is the only feature that exactly identifies the site of the lesion. Both angiography and CT scan allow a near definitive diagnosis of meningioma; because of their location it is almost always impossible to remove these tumours completely. Actually the best treatment is a piecemeal subtotal microsurgical removal via a subtemporal approach. Radiotherapy is indicated for partially resected lesions. On the basis of the revision of the anatomy of this region and looking forward to a widespread use of the Cavitron in neurosurgery, a more radical approach to this lesion is foreseen.

Surgical management of acute cerebellar infarction.

After reviewing the literature, a personal series of 10 adult patients with cerebellar infarction diagnosed by CT scan is described. The clinical picture in young adult men is characterized by rapid onset of headache, vomiting, vertigo, ataxia and blurred vision. After this sudden onset the patients may present a stable course or a rapid or delayed onset of brain stem compression, revealed by impairment of consciousness. CT scan is the diagnostic method of choice. The correlation between angiographic and CT localization of the infarction is not good. For therapy the following policy is suggested: in alert and clinically stable patients: medical treatment (mannitol, glycerol, dexamethason), ICP and serial CT monitoring; in alert patients with hydrocephalus or mass effect: medical treatment and monitoring as mentioned before; ventricular drainage if ICP surpasses 350 mm H2O; in patients with impaired consciousness and hydrocephalus or mass effect: immediate ventricular drainage. If it is not followed by prompt improvement of the level of consciousness, an emergency suboccipital craniectomy with removal of the infarcted tissue should be done.

Computerized tomography in a calcified postoperative extradural cyst.

Extradural cysts resulting from dural/arachnoidal tears are unusual postoperative complications. A case of a calcified cyst is reported, emphasising its mechanism of formation, clinical significance and radiographic features. It is quite surprising today that the question should still arise as to whether computerized tomography is able to enrich the process of diagnosis, and if so in what circumstances.

Arteriovenous shunts between dural branches of the carotid artery and the cavernous sinus.

Three cases with dural arteriovenous shunts of the cavernous sinus are reported. The clinical signs usually were mild and included frontal headache, dilated conjunctival veins, exophthalmos, bruit, and oculomotor nerve palsy. Arterial contributions to the fistulae arose from meningeal branches of the internal and external carotid arteries. The precise diagnosis was made by selective angiography supplemented by subtraction and magnification techniques. The distal occlusion of the feeding arteries close to the shunt offers advantages when compared with conventional vessel ligation because of a more effective exclusion of vascular abnormalities from the circulation.

Choroid plexus papilloma of the third ventricle.

Choroid plexus papillomas are rarely located in the third ventricle. The case of a 49-year-old man who had a total microsurgical excision of such a lesion is reported. The neuroradiological features and the surgical results are discussed, with a review of 25 other cases reported in the literature. Microsurgical technique made possible a good exposure and successful complete removal of the tumor.

Intracerebral haemorrhage: an attempt at statistical assessment for operability.

A series of 88 patients, who underwent operation for intracranial haemorrhage, is reported. The outcomes are assessed in order to evaluate the operability in relation to the patient's age, the type of onset, the site of haemorrhage, the conscious level, the interval between accident and operation, cardiovascular disease and the dysmetabolic values. A numerical value has been assigned to each factor considered; than the correspondence between these values and the importance of each factor in relation to the clinical state has been analysed. The authors finally point out that their study, although it has a merely indicative significance, agrees sufficiently with the clinical results, as to give a useful pattern for a statistical approach to the question of intracerebral haemorrhage, offering in the meantime hopeful aids to diagnosis.

[Radiological investigation of prolactin-producing pituitary microadenomas (author's transl)].

The CT scans and thin section sellar tomograms of 12 patients with amenorrhea, galactorrhea and hyperprolactinemia syndrome were analyzed. Three patients showed a remodeled sella on plain X-ray of the skull and a protrusion of the suprasellar cistern below the diaphragmatic line on pneumoencephalography (empty sella). CT scan confirmed the low absorption values within the sella and showed an intrasellar area of increased density after contrast infusion. In 9 patients, thin section tomograms showed an abnormal sellar configuration. 5 of these patients had an eccentric, high density area adjacent to the sellar floor on postcontrast CT scans. The remaining 4 patients did not show postcontrast enhancement.

Computed tomography for diagnosis of empty sella associated with enhancing pituitary microadenoma.

Ten cases of primary empty sella with clinical findings of a secreting pituitary adenoma were studied using computed tomography (CT). Scans performed before contrast medium infusion confirmed the diagnosis of empty sella. After infusion, eight cases were found to have a nodular area of increased density within the sella turcica. In two patients, the enhancement probably corresponded to the pituitary stalk; the other six patients demonstrated CT evidence of pituitary microadenoma. These six patients had surgical confirmation of the existence of neoplasm. Tomodensitometric diagnosis of empty sella combined with microadenoma allows transsphenoidal microsurgery for complete tumor removal with preservation of the residual pituitary gland. For comparison, in a series of 21 patients suspected of having microadenomas, but without evidence of empty or enlarged sella, enhancing microadenomas were shown in 13 (62%).
