Hematomas na fossa craniana posterior. Cysticercosis is one of the most severe parasitic diseases of the nervous system. When located in the posterior fossait presents a dramatic picture of intracranial hypertension. Hematomas na fossa craniana posterior Haematomata in the posterior fossa. Six cases of sub-tentorial haematomata one chronic sub-dural, four intra-cerebellar, one extra-dural are reported.

Emphasizing the relative rarity of haematomata in the posterior cranial fossathe author claims the necessity of complementary examinations for proper diagnosis, indispensable for adequate surgical treatment.

Cinquenta ossos temporais foram dissecados. The classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation.

To describe a new approach to expose the basal turn of the cochlea in cochlear implant surgery through the middle cranial fossa. Fifty temporal bones were dissected in this anatomic study of the temporal bone. Cochleostomies were performed through the middle cranial fossa approach in the most superficial portion of the basal turn of the cochlea, using the meatal plane and.

Full Text Available The improvement of surgical techniques as well as the introduction of new surgical instruments promoted the use of keyhole craniotomies in neurosurgery.

We evaluated the technical aspects of the supra-orbital keyhole approach melamd the indications, limitations, and complications of this approach to treat anterior cranial fossa and parasellar meningiomas. Maximal tumor diameter ranged from 1. Gross total resection was done in 20 All tumors were histologically benign.

One patient experienced transitory hemiparesis.

There was one case of meningitis and one mortality. Follow-up ranged between 6 to 66 months mean The supra-orbital keyhole craniotomy is a useful minimally invasive approach to treat selected anterior fossa and parasellar meningiomas. Todos os tumores eram histologicamente benignos.

O seguimento variou de 6 a 66 meses m.

Epidermoid cyst of the posterior fossa: Full Text Available Epidermoid cysts of the central nervous system are uncommon conditions, which are frequently located in the cerebellopontine angle and around the pons. They are covered with keratinized squamous epithelium and keratin lamella, which give porqje contents a soft, white-pearly appearance.

Epidermoid cysts are mostly originated from malformations, presumably associated with surface elements of the nervous system ectoderm during the closure of the neural groove or formation of secondary cerebral vesicles. The authors describe a case of epidermoid cyst in the kelamed fossa causing hydrocephalus and review morphologic and diagnostic criteria of this lesion.

The present study was aimed at analyzing the value of the early diagnosis of hemodynamic changes in hemorrhages and hypoxic-ischemic events in premature, very-low-birth-weight neonates through the evaluation of images and resistance index measurement by means of transcranial Doppler ultrasonography.

Fifty premature, very-low-birth-weight neonates were submitted to transcranial Doppler ultrasonography with sequential transfontanellar and transtemporal techniques. Intercondylar mlamed width indexes IFWI were determined in nine adult dogs submitted to intercondylar notchplasty IN after transection of the cranial cruciate ligament CCL followed by a fascial strip melameed. Each group was then divided into three subgroups which corresponded to time of euthanasia at 30, 90 and days after surgery.

IFWI were determined, both macroscopically and radiographically, by measuring the cranial outlet of the intercondylar fossa in relation to the epicondylar width. A significant increase was observed in indexes of GI following IN, and these differed from indexes of. To distinguish healthy from pathological tissues in pediatric patients with posterior cranial fossa tumors using calculated textural parameters from magnetic resonance images.

We evaluated 14 pediatric patients with posterior cranial fossa tumors using the software MaZda to define the texture parameters in selected regions porsue interest representing healthy and pathological tissues based on T2-weighted magnetic resonance images. There was a statistically significant difference alejandri normal and tumoral tissues as well as between supposedly normal tissues adjacent and distant from the tumoral lesion.

Magnetic resonance textural evaluation is an useful tool for determining differences among various tissues, including tissues that appear apparently normal on visual analysis.

Ultrasound and magnetic resonance imaging findings in Schistosomiasis mansoni: There is no study relating magnetic resonance imaging MRI to ultrasound US findings in patients with Schistosomiasis mansoni. Fifty-four patients mean age We named this the fatty hilum sign.

One of the 47 patients melwmed MRI evidence ofperiportal fibrosis had had his gallbladder removed previously. Echogenic thickening of thegallbladder wall and of the main portal vein mmelamed heretofore attributed to fibrosis were frequentlyidentified as fat tissue in MRI.

However, the gallbladder wall thickening shown in US expandedgallbladder fossa in MRI is probably secondary to combined hepatic morphologic changes inschistosomiasis, representing severe liver involvement. Magnetic resonance imaging textural evaluation of posterior cranial melzmed tumors in childhood; Avaliacao textural por ressonancia magnetica dos tumores da fossa posterior em criancas. The aim of this study is to contribute to the knowledge to assists the nursing staff to identify the most common types of venous formations of the cubital fossa region, and also focus on the importance of always being alert to unusual cases as that reported here.

Through a literature review, we found alfjandro the venous formations of this alejzndro can be classified into five common types, bring the Type II the was most frequent. Posterior fossa epidural hematoma. CT demonstrated posterior fossa epidural hematoma in three patients with head trauma in whom this diagnosis was not clinically apparent.

No patient was in stupor or coma and no patient experienced a lucid interval. Only one patient had signs referable to the posterior fossa. Two patients had occipital skull fracture disclosed by plain radiographs.

CT revealed a melamd biconvex hematoma in two cases, and a bilateral hematoma with supratentorial extension in the third. All patients melsmed suboccipital craniectomy and recovered. Therapeutic success in these cases was facilitated by early CT and the rapid disclosure of the unsuspected posterior fossa lesions. CT showing contiguous hematoma below and above the tentorium cerebelli after posterior head trauma is highly suggestive of epidural hematoma arising from the posterior fossa.

Hypogonadotrophic hypogonadism can result from different abnormalities in the central nervous system. The clinical picture depends upon the time of onset the deficiency, the magnitude of the gonadotropins deficiency and whether there are other pituitary hormone deficiencies as well.

We report on a year-old boy, who was investigated because of pubertal alehandro growth delay. He also had learning. This Formation, seen here as the raised plateau in the upper two-thirds of the image, is a soft, easily eroded deposit that extends for nearly 1, km along the equator of Mars. In this region the deposit has been heavily eroded by the wind to produce a series of linear ridges called yardangs.

These parallel ridges point in direction of the prevailing winds that carved them, and demonstrate the power of martian winds to sculpt the dry landscape of Mars. The Medusae Fossae Formation has been completely stripped from the surface in the lower third of the image, revealing a harder layer melxmed that is more resistant to wind erosion.

The easily eroded nature of the Medusae Fossae Formation suggests that it is composed of weakly cemented particles, and was most likely formed by the deposition of wind-blown dust or volcanic ash.

Several ancient craters that were once completely buried by this deposit are being exposed, or exhumed, as the overlying Medusae Formation is removed. Very few impact craters are visible on this Melamsd, indicating that the slejandro seen today is relatively young, and that the processes of erosion are likely to be actively occurring. The Story Medusa of Greek mythology fame, the name-giver to this region, had snaky locks of hair that could turn a person to stone.

Wild and unruly, this monster of the underworld could certainly aoejandro havoc on the world of the human imagination. As scary as she was, Medusa would have no advantage over the aoejandro, masterful winds blowing across Mars, which once carved the streaky, terrain at the top of this image. Wild and whipping, these winds have slowly eroded away the ‘topsoil,’ revealing ancient craters and other surface features they once covered.

The loosely cemented particles of this ‘topsoil’ are likely made up of dust. Report of two cases. A study was made of a patient with carcinoma of the hypophisis which invaded the sphenoid bone and made protrusion under the nasopharyngeal mucosa, and that of alejandfo patient with craniopharyngeoma.

The patients had no symptoms proper to the tumors but presented several episodes of meningitis. The presence of the tumor, in both cases, was evidenced lately, when the failure of the antibiotic therapy became patent leading to the. Acestrorhynchus lacustris, Prochilodus lineatus, Schizodon borellii, Serrasalmus maculatus e Serrasalmus marginatus. Fish were captured in different locations of the floodplain in March, June and September, A total of 73 specimens Characiformes were collected, belonging to 4 distinct families and 5 species: Acestrorhynchus lacustris Acestrorhynchidae, Schizodon borellii Anostomidae, Prochilodus lineatus Prochilodontidae, Serrasalmus marginatus and Serrasalmus maculatus Serrasalmidae.

Among 73 fishes examined, 53 were parasitized by nasal fossae copepods, varying from 1 to parasites per host. Parasites found belonged to 3 known species: Uncommon evolution of probable central nervous system histoplasmosis: A case report with magnetic resonance images; Evolucao incomum de provavel histoplasmose de sistema nervoso central: Relato de caso com imagens por ressonancia magnetica.

Disciplina de Neurologia e Neurocirurgia]. Centro de Tomografia; Bozo, Marlon K. We report a case of a young immunocompetent patient with probable central nervous system histoplasmosis with evolutive peculiar findings seen on magnetic resonance imaging. Leptomeningeal thickening was initially observed which subsequently became a posterior fossa granuloma. The diagnosis of fungal infection was only reached by histopathological study and the treatment was alemandro on long term porqye with fluconazole wth good initial response.

Epidural hematomas of posterior fossa. Full Text Available Background. They are most frequently encountered posttraumatic mass lesions in the posterior fossa.

The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma.
