Tolosa-Hunt Syndrome

Rev. bras. oftalmol; 77 (5), 2018
Abstract We present a case study of Tolosa-Hunt syndrome, a rare idiopathic disease, that is characterized by painful ophthalmoplegia of strong intensity, generally affecting the third cranial nerve, and, less frequently, the fourth or the sixth cranial nerves. Usually, there is no visual impairment. The...

Importancia del diagnóstico histopatológico en el tratamiento de las lesiones del tronco cerebral en adultos
Relevance of histopathological diagnosis in the treatment of brainstem lesions in adults

Medicina (B.Aires); 78 (5), 2018
Los tumores del tronco cerebral son infrecuentes en la población adulta. Las controversias surgen cuando se considera la necesidad de confirmar el diagnóstico histopatológico en esta área elocuente del cerebro, balanceando los beneficios de obtener un diagnóstico certero y las desventajas de los pro...

Age-related changes of the cerebral ventricles of healthy domestic cats

Pesqui. vet. bras; 38 (10), 2018
This study aimed to determine age-related changes of the cerebral ventricles of healthy non-brachycephalic domestic cats by the acquisition of brain MRI images of 12 adult (1 to 6 years), 11 mature (7 to11 years) and 10 geriatric (12 years or more) cats. Our hypothesis is that the cerebral ventricular sy...

New quantitative method to measure the Hill-Sachs lesion: validation of Hardy's radiographic method for MRI/AMRI

ABSTRACT Objective: To validate Hardy's radiographic method for magnetic resonance imaging/magnetic resonance arthrography (MRI/MRA) in the assessment of Hill-Sachs lesion (HSL) involvement in patients with a history of anterior shoulder instability. Methods: This study retrospectively evaluated 53 sho...

Lesiones destructivas de la línea media facial secundarias al consumo de cocaína: caso clínico

Anatomical parameters of the rectus capitis posterior major and obliqus capitis inferior muscles based on an oblique sagittal magnetic resonance scan method

Int. j. morphol; 36 (3), 2018
The deep suboccipital muscles has been shown to connect the spinal dura mater via dense connective tissue termed the myodural bridge (MDB). The MDB has both physiological and clinical implications. Data on morphological and imaging anatomical parameters of the deep suboccipital muscles are scare. In this...

An Improved Classification System for Brain Tumours Using Wavelet Transform and Neural Network

West Indian med. j; 67 (3), 2018
ABSTRACT This paper presents an improved classification system for brain tumours using wavelet transform and neural network. The anisotropic diffusion filter was used for image denoising, and the performance of the oriented rician noise reducing anisotropic diffusion (ORNRAD) filter was validated. The se...
