Abstract
 Introduction: the aim of this study was to compare radiologically effect disc on Root thicknesses in patients with acute herniation.
 Methods: It performed by measuring same level thickness lumbar MRI images presenting herniation symptoms.
 Findings: Lumbar 95 were compared radiologically. statistically determined that nerve root side exposed compression increased other...

Lymphocytic hypothalamitis (LHT) is a rare disease characterized by pituitary dysfunction, autonomic instability, metabolic disturbances, and neuropsychiatric disorders. We report the case of a 30-year-old man found to have LHT that progressed despite treatment with methylprednisolone and intravenous immunoglobulin (IVIG). A literature review was conducted to identify prior studies pertaining t...

PRIMARY OBJECTIVE Chiari malformation is defined as herniation of the cerebellar tonsils through the foramen magnum, also known as cerebellar tonsillar ectopia (CTE). CTE may become symptomatic following whiplash trauma. The purpose of the present study was to assess the frequency of CTE in traumatic vs non-traumatic populations. STUDY DESIGN Case-control. METHODS AND PROCEDURES Cervical MR...

Spontaneous intracranial hypotension (SIH) is classified as a decrease in cerebrospinal fluid (CSF) pressure secondary to a CSF leakage and consequent descent of the brain into the foramen magnum. Diagnosing SIH can be difficult due to its overlapping findings with Arnold-Chiari type 1 Malformation (CM1) where the cerebellar tonsils herniate into the foramen magnum. The similarity of both condi...

little information is at hand on the diagnostic values of the clinical symptoms and signs in the level diagnosis of patients with lower lumbar disc herniation.  we examined one hundred and thirty nine consecutive candidates for lower lumbar discectomy.  monoradicular pain with signs attributed to the fifth lumbar and first sacral root dysfunctions were evaluated independently in each patient.  ...

We describe a patient who presented with headaches and vomiting. A computerised tomogram (CT) of brain failed to demonstrate bilateral subdural collections subsequently shown on magnetic resonance imaging (MRI). This case illustrates that an essentially normal CT scan does not always exclude significant intracranial pathology. CASE REPORT A 44 year old female presented with a four month history...

BACKGROUND Among head and neck cancers, human papillomavirus type 16 (HPV16) is associated with tonsillar carcinomas. Despite this, no HPV16-positive tonsillar cancer cell line has been established in nude mice. METHODS Fresh tonsillar carcinoma biopsies were obtained from 23 patients and implanted subcutaneously into nude mice (BALB/c, nu/nu). RESULTS After 7 months, one xenograft was esta...

We describe the case of a short-statured 12-yr-old boy who developed a Chiari type 1 malformation associated with central sleep apnea after administration of high-dose GH therapy, which he had been receiving since the age of 10 yr and 4 mo. He responded well to GH therapy, and his height increased by 18.8 cm in 2 yr. At 12 yr and 4 mo of age, his mother reported that he had developed sleep apne...

STUDY DESIGN Retrospective cohort study. PURPOSE To compare surgical results of foramen magnum decompression with and without duraplasty in Chiari malformation type 1 (CM-1) associated syringomyelia (SM). OVERVIEW OF LITERATURE The optimal surgical treatment of CM-1 associated with SM is unclear. METHODS Twenty-five cases of CM-1 with SM were included. There were 12 patients (48%) in the ...

BACKGROUND Presenting symptoms, treatment considerations, and outcome are strongly related to the extension of vestibular schwannomas (VS). The aim of the current retrospective study was to analyze the clinical features, microsurgical treatment, and outcome of VS with brainstem compression. METHODS Forty-nine patients presented with VS (Hannover grading scale T4a or T4b) in our department. A ...
