La localisation pariétale thoracique chez l'enfant est une forme très rare de tuberculose. Son diagnostic est souvent difficile nécessitant le recours à la biopsie chirurgicale. Nous rapportons le cas d'une jeune fille de 14 ans, présentant depuis un mois et demi une tuméfaction de la paroi thoracique antérieure. La tomodensitométrie thoracique a objectivé un processus lésionnel pariétal para-sternal droit à limites imprécises responsable d'une érosion du sternum. L'examen anatomo-pathologique des biopsies de la coque d'abcès a confirmé le diagnostic de tuberculose caséo-folliculaire. Le traitement anti-bacillaire a permis une évolution favorable.

Facial nerve aplasia is an extremely rare condition that is usually syndromic, namely, in Moebius syndrome. The occurrence of isolated agenesis of facial nerve is even rarer, with only few cases reported in the literature. We report a case of congenital facial paralysis due to facial nerve aplasia diagnosed on MRI, while no noticeable abnormality was detected on the temporal bone CT.

RésuméSi la hernie inguinale est une pathologie fréquente en chirurgie digestive, elle touche rarement la vessie. La hernie vésicale ne se manifeste généralement par aucun signe particulier, et son diagnostic est le plus souvent peropératoire, parfois même postopératoire lors de l'apparition de complications. Le traitement est chirurgical ; il consiste à réintégrer la partie herniée et à réaliser une pariétor-raphie. Le présent article fait état de l'observation médicale d'un patient présentant une hernie vésicale de découverte peropératoire.

Les carcinomes thyroïdiens sont des tumeurs malignes assez rares, représentant 1% des cancers. Ils sont généralement de bon pronostic, et présentent des aspects cliniques et évolutifs variés selon leur origine histologique. Notre travail est une étude rétrospective portant sur 102 cas de carcinomes de la thyroïde, colligés sur un nombre total de 811 gestes chirurgicaux thyroïdiens, au service d'oto-rhino-laryngologie et de chirurgie cervico-faciale de l'hôpital militaire Avicenne de Marrakech, sur une période de 8 ans, allant de janvier 2006 à décembre 2013. Les carcinomes thyroïdiens atteignent le sujet jeune avant l’âge de 50 ans, en particulier le sexe féminin. La tendance dans les pays en voie de développement, comme dans le monde entier est en croissance continue, ceci peut être expliqué par l'amélioration des outils d'imagerie et des moyens diagnostiques cytologiques et anatomo-pathologiques.

BackgroundRadiotherapy associated with chemotherapy is a well-established treatment modality for locally advanced non-small cell lung cancers. Radiation-induced second malignancies, particularly radiation-induced sarcomas, are rare. Some authors reported a recent increase in the incidence of this rare complication, especially because of the improved prognosis and survival of patients after radiotherapy. Pathogenic mechanisms of radiation-induced sarcomas are poorly understood. However, diagnosis criteria are well established. Treatment options must be discussed and adapted to the patient’s profile. Surgery in irradiated tissue is challenging, with limited treatment options with chemotherapy and radiotherapy.Case presentationWe report the case of a 62-year-old Moroccan man diagnosed as having chondrosarcoma of his right scapula, who was irradiated 10 years ago for stage IIIB non-small cell lung cancer. This case was managed by a complete resection of the tumor with good functional and oncological outcomes. To the best of our knowledge, the scapular location of radiation-induced sarcoma after irradiation for lung cancer has never been described in the literature.ConclusionRadiation-induced sarcoma of the scapula represents a rare situation that must be actively researched to have access to an optimal therapeutic approach.

Originally recognized by Cushing and Bailey, hemangioblastoma is a developmental vascular neoplasm that is predominantly found in the posterior fossa. It is a highly vascularized tumor, with well-differentiated histologic features. Although rare, it remains the most common primary tumor of cerebellum in adults, along with metastases. MRI is the gold standard, allowing a precise characterization of the lesion's features, and its relationship with the surrounding structures. We report the case of a patient with a cerebellar symptomatology, in whom brain MRI raises the diagnosis of hemangioblastoma, which was then confirmed by histopathologic examination.

“CADASIL” is a genetic microangiopathy with autosomal dominant inheritance. Its epidemiology and physiopathogenesis are poorly specified, but it is proven that this disease is due to a mutation of the NOTCH3 gene resulting in a loss of elasticity of the media of the affected vessels. The clinical expression is variable, dominated by migraine attacks with aura, ischemic vascular accidents and psychiatric disorders, in particular depression. MRI is essential for diagnosis even in the pre-symptomatic phase. It shows signal abnormalities in the basal ganglia and white matter, characteristic especially when located in the anterior part of the temporal lobes. The management of CADASIL is multidisciplinary, psychological for the most part without specificity of a particular treatment.

The appendiceal mass is a common complication in the natural evolution of acute appendicitis, often manifested by a mass in the right quadrant, ranging from the appendiceal phlegmon to the collected abscess. Our study consist on determining the epidemiological, clinical, diagnostic and therapeutic aspects in the care of the appendiceal plastron, as well as the role of surgery in this special care. This is a retrospective study including 30 cases of appendiceal mass, excluding appendicular abscesses, collected to the general surgery department of the military hospital Avicenne of Marrakesh, over a period of 5 years,
