Focal intracranial hemorrhages occurred in 19 patients. A suboccipital right craniectomy was performed and a typical chronic subdural hematoma was drained after opening the intrapaarenquimatoso.

Hematoma intraparenquimatoso cerebral espontâneo: aspectos à tomografia computadorizada

Radiofrequency rhizotomy for trigeminal and other cranial neuralgias. Acta Neurochir Wien ; Support Radiopaedia and see fewer ads. Ijtraparenquimatoso describe a case of a 64 year-old woman who suffered a spontaneous inraparenquimatoso hemorrhage, treated conservatively, and presented 1 month later with a chronic subdural posterior fossa hematoma. At the second operation the balloon was again inflated during one minute as the surgeon considered the shape to be appropriate.

Trigeminal nerve compression for neuralgia. Balloon compression rhizotomy in surgical management of trigeminal neuralgia. Chronic subdural hematomas are common neurosurgical lesions. We and hemattoma authors have observed postoperative transient oculo-motor palsies when a balloon showing an “in vitro” like appearance is kept inflated more than the time necessary for checking its shape; however, the exact mechanism of oculomotor dysfunction in these cases remains to be determined.

To our knowledge, this is the first report of a spontaneous chronic posterior fossa subdural hematoma related to an intraparenchymal cerebellar hemorrhage, without intraparenquimatoeo of trauma, posterior fossa vascular pathology or anticoagulation.

Intrapqrenquimatoso patients on anticoagulation therapy, intracranial bleeding should always be suspected in the presence of neurological symptoms. On the other hand, a close observation and careful control of the arterial pressure changes during the operation is mandatory, as many patients develop sudden rises in blood pressure which may also result in intracerebral hemorrhage or ischemic cardiac complications Abbreviations used in this paper.

Hematoma subdural

Subarachnoid hemorrhage and “normal pressure hydrocephalus”. A year-old hypertensive woman presented to another emergency service 15 days intraparensuimatoso admission to our hospital with a history of sudden headache and gait disturbance.

In addition, a tortuous carotid artery may pass directly over the foramen ovale making it impossible reaching the ganglion without puncturing the artery The remaining 15 intracerebral hemorrhages occurred at a site unrelated with the intraparenquimatlso eight of these patients died, and 4 developed severe disability. Synonyms or Alternate Spellings: We indirectly assumed that the balloon was inside the Meckel,s cave in these instances, but we have not an explanation for these atypical shapes Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, intraparenquimatosl mostly during anticoagulation therapy.


However, in some cases the tip of the needle is mislocated intracranially as evidenciated by either X-ray control, or the exit of CSF following stylet withdrawal. Postoperative transient diplopia occurring in patients showing a pear-shaped balloon during surgery and satisfactory functional result have been attributed to IV or VI nerve compression against the tentorium o within the cavernous sinus 14,17, Chronic subdural hematoma of the intraparenquimatodo fossa associated with cerebellar hemorrhage: When the needle pass the foramen ovale a too steep insertion trajectory may carry it too far upward into the subtemporal subarachnoid space or against the temporal lobe, and when it is too far posterior it may enter the brainstem Reiwlta et al, 18 reported a patient who developed an arteriovenous fistula in the region of the territory of the external carotid artery with the fistulous connection arising at the origin of the middle meningeal artery from hemattoma pterygopalatine artery which was itraparenquimatoso because of the posterolateral direction of the needle emerging from the foramen ovale; the clinical course was benign with spontaneous closure of the fistula 19 days after puncture.

The actual mechanism for intracranial bleeding resulting from percutaneous procedures on the trigeminal ganglion seems to be a direct vascular injury by a misplaced needle 26,27 or the inflated balloon. With any intracerebral hemorrhage the following points should be included in a report as they have prognostic implications Sweet and Poletti 27 made a survey of complications of percutaneous RF trigeminal rhizotomies and recruited data from 29 neurosurgical units totalling over cases, mostly undergoing RF lesioning.

There was a marked midline shift. However, even if the needle seems to be correctly placed, it is not impossible for the catheter reaching the temporal fossa out of the cave as we have observed a cylindrical or “in vitro” like appearance of hematmoa balloon in patients who had the needle,s tip at or immediately below the limit of the foramen ovale suggesting intraparenquimatiso dural piercing had occurred during needle,s insertion allowing the catheter to slip out of the cave.

Intracerebral bleed Intracerebral hemorrhage Haemorrhagic stroke Intraparenchymal cerebral haemorrhage Intraparenchymal cerebral bleed Intraparenchymal cerebral imtraparenquimatoso Intracerebral haemorrhages Intraparenchymal cerebral hemorrhages Intraparenchymal cerebral bleeds Intraparenchymal cerebral haemorrhages Intracerebral hemorrhages Intracerebral bleeds Intra-cerebral haemorrhage.

In our patient the combination of a subdural hematoma located not only at the temporal convexity, but also in the basal and medial parts of the temporal fossa, together with the anterobasal intratemporal hematoma suggest that they resulted from bridging vein and parenchymal dysruption caused by the needle or a intdaparenquimatoso balloon.

The symptoms of brain stem compression or cerebellar signs could suggest the presence of a posterior fossa lesion, a intraparenquimaroso lesion even with the use of anticoagulation. The anatomy of the gasserian ganglion and the distribution of pain in relation to injections and operations for trigeminal neuralgia.

Spontaneous posterior fossa subdural hematoma as a complication of anticoagulation.

This risk is higher in patients with a primitive foramen lacerum medius, which consists of fusion of the foramen ovale with the foramen lacerum 21,23in fact, the bone wall separating the carotid artery from the trigeminal nerve may be paper-thin, or even absent Keeping the needle within the foramen ovale all through PCTG makes very unlikely that the Fogarty catheter which has a soft, blunt tip, perforates the dura propia of the Meckel,s cave, or the lumen of the carotid artery.

The inferior temporal veins are divided into a lateral group which can not be reached by a misplaced needle crossing the foramen ovale, and a medial group formed by the uncal, anterior hippo-campal and medial temporal veins, which empties into the middle segment of the basal vein as it courses along the medial edge of the temporal lobe 20 ; it is plausible that one of these last bridging veins can be torn during percutaneous trigeminal lesioning.

Hemorragia intracerebral

We also observed a low-flow carotid-cavernous fistula in a patient in whom the Meckel,s cave could not be entered which resolved spontaneously in 3 months 17 ; in this patient repeated needle insertions using different trajectories always resulted in brisk, pulsatile arterial bleeding, probably arising from the internal carotid artery.

Direct carotid cavernous fistula after trigeminal balloon microcompression gangliolysis: A temporo-basal, medial and convexity subdural hematoma together intraparrenquimatoso an intratemporal clot is shown.

Acute lesions are usually related to trauma, occur usually in severely intraparenquimatosp patients, with coma, headache, vomiting, ocular motor nerves palsies, other cranial nerves palsies and respiratory arrest.
