Aberrant Course of the Intratemporal Facial Nerve in Children with Congenital Hearing Loss.

Congenital facial nerve (FN) malformations are uncommon. Our aim is to determine the clinical and radiological features of FN malformations along with the associated cochlear and vestibular malformations. We conducted a retrospective study including children with a profound sensorineural hearing loss who were candidates for cochlear implantation.

Congenital crico-thyroid dysplasia: a comprehensive description.

Introduction: We describe a first case of human congenital crico-thyroid dysplasia associated to a right sided aortic arch and an aberrant subclavian artery.

Case Presentation: Our patient presented with a two-weeks history of acute dyspnea, and reported hoarseness since his childhood. An urgent tracheotomy was performed, followed by direct laryngoscopy.

Intramedullary spinal cord metastasis from breast cancer: an ambiguous entity.

Intramedullary spinal cord metastasis (IMSC) from solid tumors is rare. In this report, we describe the case of a patient treated at our center for breast cancer with intramedullary spinal cord metastases without bone and brain metastases or meningitis. Management of the disease remains challenging even with recent advances in the treatment of metastatic breast cancer.

Maxillary Sinus Epidermoid Cyst: A Case Report.

The preoperative diagnosis of a paranasal epidermoid cysts (EC) is challenging and is frequently mistaken. We present the case of a patient who developed a swelling on the left side of the face. The clinical examination showed a fixed and poorly defined swelling in the left maxillary region, with a slightly painful bulge in the upper vestibular peri-gingival area.

New Contrast Enhancement Method for Multiple Sclerosis Lesion Detection.

Multiple sclerosis (MS) is one of the most serious neurological diseases. It is the most frequent reason of non-traumatic disability among young adults. MS is an autoimmune disease wherein the central nervous system wrongly destructs the myelin sheath surrounding and protecting axons of nerve cells of the brain and the spinal cord which results in presence of lesions called plaques.

Exceptional Renal Metastasis from Adenoid Cystic Carcinoma of the Nasal Cavity and Literature Review.

Adenoid cystic carcinoma (ACC) is a rare malignant cancer that arises from secretory glands. Slow growth, perineural invasion, and late recurrences are the main characteristics of ACC. Only few cases of kidney metastases from ACC have been reported in the literature.

Retropharyngeal edema secondary to superior vena cava syndrome revealing Behcet's disease.

Retropharyngeal edema, uncommon in superior vena cava syndrome, can exceptionally represent the first manifestation of Behcet's disease, which should be taken into account in the differential diagnosis of this condition.

Deep Convolutional Encoder-Decoder algorithm for MRI brain reconstruction.

Compressed Sensing Magnetic Resonance Imaging (CS-MRI) could be considered a challenged task since it could be designed as an efficient technique for fast MRI acquisition which could be highly beneficial for several clinical routines. In fact, it could grant better scan quality by reducing motion artifacts amount as well as the contrast washout effect. It offers also the possibility to reduce the exploration cost and the patient's anxiety.

Denoising and contrast-enhancement approach of magnetic resonance imaging glioblastoma brain tumors.

We investigate a new preprocessing approach for MRI glioblastoma brain tumors. Based on combined denoising technique (bilateral filter) and contrast-enhancement technique (automatic contrast stretching based on image statistical information), the proposed approach offers competitive results while preserving the tumor region's edges and original image's brightness. In order to evaluate the proposed approach's performance, quantitative evaluation has been realized through the Multimodal Brain Tumor Segmentation (BraTS 2015) dataset.

Rank-Two NMF Clustering for Glioblastoma Characterization.

This study investigates a novel classification method for 3D multimodal MRI glioblastomas tumor characterization. We formulate our segmentation problem as a linear mixture model (LMM). Thus, we provide a nonnegative matrix from every MRI slice in every segmentation process' step.

Severe head injury among children: prognostic factors and outcome.

Aim: To determine predictive factors of mortality among children after traumatic brain injury.

Methods: A retrospective study over 8 years of 222 children with severe head injury (Glasgow Coma Scale score < or = 8) admitted to a university hospital (Sfax, Tunisia). Basic demographic, clinical, biological and radiological data were recorded on admission and during intensive care unit stay.
