Audiological findings in a case of cerebellar angioreticuloma

چکیده
The aetiology of neurosensorial damage with unilateral hearing loss and/or tinnitus and dizziness can often be difficult to determine because they may be caused wide variety of pathologic processes and a variety of diagnostic tests are needed in initial evaluation. In this paper, the authors describe, the techniques and indications of neuroimaging for evaluation of auditory symptoms. Auditory brainstem response (ABR) testing is still the choice when condition is suspected. We present a study of one patient with unilateral tinnitus, with no significant hearing loss and normal ABR: the patient underwent MRI of the district brain and the internal auditory channel (AIC) that showed the presence of a rare intracranial neoplasm, namely cerebellar angioreticuloma.

Cerebellar pilocytic Astrocytoma is a benign tumor, acounts for 80% of all cerebellar Astrocytoma, and has a relatively good prognosis. This tumor usually presents with Ataxia and in the case of hydrocephaly with raised intracranial pressure signs such as headeach, and vomiting. Treatment of this tumor is complete resection and if hydrocephally is present V.P. shunt should be inserted. In the c...

Background: The cerebellum is the most important portion of the brain, which audits our acts and establishes balance. Symptoms from a cerebellar stroke happen suddenly. In addition to specific cerebellar signs and symptoms, other common symptoms of a cerebral stroke include dizziness, headache, nausea, vomiting, double vision, tremor, and vertigo. These symptoms can be confused with other situa...

Introduction: Noonan syndrome (NS) is a heterogeneous genetic disease that affects many parts of the body. It was named after Dr. Jacqueline Anne Noonan, a paediatric cardiologist.Case Report: We report audiological tests and auditory brainstem response (ABR) findings in a 5-year old Malay boy with NS. Despite showing the marked signs of NS, the child could only produce a few meaningful words. ...
متن کاملAn inward current induced by a putative cyclic nucleotide-gated channel in rat cerebellar Purkinje neurons
The roles of cyclic nucleotide-gated (CNG) channels in sensory transduction have long been recognized. More recent studies found that CNG channels are distributed in multiple brain regions involved in memory and learning, including the cortex, hippocampus and cerebellum. These findings suggest that their functions are not limited to sensory perception, but also to neuronal plasticity phenomena,...
