1/11. Spontaneous cerebrospinal fluid leakage and middle ear encephalocele in seven patients.Isolated cases of spontaneous cerebrospinal fluid (CSF) leakage with and without middle ear encephalocele have been reported. These leaks are usually accompanied by episodes of recurrent meningitis, hearing loss, or chronic headache. In this article, we report seven new cases of spontaneous CSF leakage. Six of these patients had conductive hearing loss and serous otitis media, and three had recurrent meningitis. Prior to a definitive diagnosis, six patients had received myringotomy tubes, which produced profuse clear otorrhea. Three patients had positive beta-2 transferrin assays. Computed tomography and magnetic resonance imaging confirmed a defect in the temporal bone tegmen. A combined transmastoid and middle fossa surgical approach with a three-layer closure was used to repair the tegmen defect. All patients had a lumbar drain placed prior to surgery. In addition to describing the seven new cases, we review the history of CSF leakage and discuss diagnostic methods, surgical findings, and our recommendations for management.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |
2/11. petrositis and cerebellar abscess complicating chronic otitis media.A 12-year-old girl with chronic otitis media complicated by petrositis and cerebellar abscess is presented. Early surgical intervention, in combination with broad-spectrum antibiotics, provided a good outcome. life-threatening complications of otitis media, although rare, still occur in developed countries.- - - - - - - - - - ranking = 6keywords = otitis (Clic here for more details about this article) |
3/11. Subdural empyema and cerebellar abscess due to chronic otitis media.The infratentorial variety of the subdural empyema, with or without coexisting cerebellar abscess, is a rare clinical entity that carries a high mortality rate. We briefly describe the case of a 49-year-old man presented with severe debility, fever and an obviously neglected chronic otitis media. The patient had refused surgical treatment several months ago. After admission, his level of consciousness began to deteriorate, and the radiological studies showed infratentorial subdural suppuration extending into the right cerebellar hemisphere, along with chronic pyogenic infection of the middle ear and the mastoid process. Radical mastoidectomy was performed first, followed by extensive right posterior fossa craniectomy. The two subdural collections and the cerebellar abscess were successfully evacuated. Subsequently, he received post-operative antibiotic treatment for 6 weeks. At follow-up, 10 months after surgery, his neurological recovery was complete except for a minor residual cerebellar dysfunction on the right. This unusual case highlights that in patients presented with severe intracranial complications of chronic otitis media, early diagnosis and radical surgical intervention may be life saving.- - - - - - - - - - ranking = 6keywords = otitis (Clic here for more details about this article) |
4/11. Familial type IV hypertriglyceridemia presenting as hemiparesis with cerebellar signs.stroke in pediatric patients is distinctive as compare to adults. The authors report a rare case of familial hypertriglyceridemia type IV who had left hemiparesis with cerebellar signs. There was no history of oral trauma, head injury, convulsions, acute gastroenteritis, meningitis or otitis media.- - - - - - - - - - ranking = 1keywords = otitis (Clic here for more details about this article) |

6/11. Postauricular cerebellar encephalocoele secondary to chronic suppurative otitis media and mastoid surgery.Cerebellar herniation into the mastoid through the posterior aspect of the temporal bone as a result of chronic suppurative otitis media and mastoid surgery is a rare event. A case is reported in which such a hernia presented subcutaneously behind the pinna; its repair is discussed.- - - - - - - - - - ranking = 5keywords = otitis (Clic here for more details about this article) |
7/11. Cavernous angioma of the cerebellum--case report.Computed tomography (CT) allows earlier diagnosis of intracranial cavernous angioma than was formerly possible. However, cerebellar lesions are uncommon. Cerebellar cavernous angioma with hemorrhage was diagnosed in a 54-year-old male who suddenly developed nausea and vomiting, then declined over the following week and developed ataxia and nystagmus. blood pressure was normal, and he had no history of hypertension or hemorrhagic diathesis. Precontrast CT revealed an irregularly-shaped, hyperdense lesion in the left cerebellum and an associated hematoma. Injection of contrast medium did not significantly enhance the lesion. Vertebral angiography demonstrated only an avascular mass in the cerebellum. A semiliquid hematoma was evacuated and a vascular nodule was removed from the posterior wall of the hematoma cavity. The histopathological diagnosis was cavernous angioma. Nine sufficiently documented reports of cerebellar cavernous angioma are reviewed and the clinical and radiological features of these lesions are discussed.- - - - - - - - - - ranking = 0.10282579863662keywords = medium (Clic here for more details about this article) |
8/11. Contrast enhancement of cerebellar infarction on computed tomography.The author analyzed the appearance on computed tomography after infusion of contrast medium of cerebellar infarction in three patients, whose diagnosis was made on the basis of clinical presentation, cerebral angiography, and sequential computed tomographic scans. Their computed tomographic appearance was not always the same as seen in the supratentorial counterpart, in showing reminiscence of an arteriovenous malformation, a leptomeningeal dissemination of a tumor or meningitis, or a neoplasm, respectively. For these reasons, it was concluded that it is important to notice the contrast-enhanced computed tomographic appearance in cerebellar infarction, when making a differential diagnosis between various pathologies in the posterior fossa.- - - - - - - - - - ranking = 0.10282579863662keywords = medium (Clic here for more details about this article) |
9/11. Intelligibility in acquired dysarthria--a neuro-phonetic approach: three case studies.A descriptive framework of phonetic parameters for the assessment of dysarthric speech is presented. The phonetic parameters examined are based on a linguistic analysis of aspects of continuous speech. The assessment thus evaluates the functional efficiency of the speech producing mechanisms in encoding the spoken medium of language. The interaction of the deviant parameters is related to the breakdown of intelligibility. Possible underlying neurological correlates are discussed. The implications for therapy using the combined phonetic and neurological information are considered. This assessment procedure is illustrated with case studies of three types of acquired dysarthria.- - - - - - - - - - ranking = 0.10282579863662keywords = medium (Clic here for more details about this article) |
10/11. Primary leptomeningeal lymphoma presenting as cerebellopontine angle lesion.We report a primary leptomeningeal lymphoma (PLML) presenting as a cerebellopontine angle lesion. CT showed slight enlargement of the ventricular system, obliteration of the basal cisterns and a dense lesion in the left cerebellopontine angle which enhanced with contrast medium. cerebrospinal fluid abnormalities included sterile lymphocytic pleocytosis without malignant cells, low sugar and high adenosine deaminase levels. An erroneous diagnosis of tuberculous meningitis was made, but autopsy revealed a leptomeningeal B-cell lymphoma with infiltration of the middle cerebellar peduncle giving the appearance of a cerebellopontine angle lesion. Seven cases of cerebellopontine angle lymphoma have previously been described, only one of which could be classified as PLML.- - - - - - - - - - ranking = 0.10282579863662keywords = medium (Clic here for more details about this article) |
