TOPIC: Critical Care TYPE: Medical Student/Resident Case Reports INTRODUCTION: A Dieulafoy's lesion was first described by Dr. M. T. Gallard in 1884, but the name followed after a French surgeon, Paul Georges Dieulafoy, who presented three cases of "submucosal arterioles" stomach 1898. Although this is rare lesion, it an important etiology gastrointestinal (GI) hemorrhage that clinicians need t...

Desmoplastic ameloblastoma (DA) is a benign but locally invasive variant of the solid/multicystic ameloblastoma (SMA). In the recent World Health Organization classification of odontogenic tumours, DA has been characterised as a variant, with specific clinical, radiographic and histopathological features. A possible 'transitional' form of DA, showing microscopic features of the desmoplastic var...

Cartilaginous metaplasia is a rare but well-documented phenomenon occurring in the wall of odontogenic keratocyst. The mural cartilage not associated with odontogenic keratocyst has been reported only once in a maxillary teratoid cyst of congenital origin to our knowledge. A case presented is a 38-year-old man with intraosseous keratinizing epidermoid cyst in the mandible, the wall of which con...

Management of the symptomatic multiple stenosis of supra-aortic vessels (MSSVs) in a "bovine" aortic arch (BAA) configuration is infrequently reported. The optimal treatment choice remains debatable. A successful hybrid treatment for a proximal critical stenosis of the innominate and left common carotid artery was performed in a high-risk patient with a tandem symptomatic lesion in the right ca...

Single organ vasculitis (SOV), or isolated vasculitis, has been described in several organs and it can be an accidental finding. We report a case of isolated necrotizing granulomatous vasculitis of the uterine cervix in a middle-aged woman, previously healthy, and sexually active, and whose human papillomavirus (HPV) DNA hybrid capture assay was positive. Systemic involvement was not detected a...

Introduction. MRgHIFU is a hybrid technology which aims to offer efficient and safe thermal ablation of targeted tumors or other pathological tissues, while preserving the normal surrounding structures unaltered. Theoretically MRgHIFU has no limitation on lesion size [1]. The main challenge is to avoid near and far field heating [2]. We demonstrate here that beam reflection on bones is a major ...
