Triple barreled aortic dissection: The Mercedes-Benz sign.

Triple barreled dissection is an extremely rare form of aortic dissection with only a few cases reported in the literature. It is characterized by 3 lumens separated by 2 intimal flaps, resembling the appearance of the 'Mercedes Benz' sign. We present an unusual case of triple barreled aortic dissection in a 71-year-old patient with history of hypertension.

Pneumosinus dilatans with shift of midline intracranial structures: A case report.

Pneumosinus dilatans (PSD) is an abnormal dilatation and enlargement of one or more paranasal sinuses, extending beyond the anatomic bony boundaries, without defect or thinning of its bony walls. It is documented by only a few reports. Usually asymptomatic, it is in general found incidentally on imaging.

Rapunzel syndrome: An infrequent cause of paediatric mechanical occlusion.

Despite numerous cases of trichobezoars reported in the literature, few Rapunzel syndromes have been described. Rapunzel syndrome is a rare case of bowel obstruction resulting from hair ingestion (trichobezoar). The obstruction can occur in any level of the intestinal tract.

Nasosinusal chondrosarcoma with orbito-cerebral extension.

Chondrosarcoma is a highly aggressive malignant tumor originating from cartilaginous and mesenchymal tissues. The aim of this report is to describe a rare case of nasosinusal chondrosarcoma with orbito-cerebral extension. Our patient was a 55-year-old with a right cheek swelling evolving over a year, with unilateral right nasal obstruction gradually becoming bilateral associated with hyposmia, bilateral exophthalmos, reduced bilateral deep visual acuity and permanent headaches.

Angiofibroma of the external auditory canal: a rare case with literature review.

Angiofibromas represent <1% of all head and neck tumors and occur primarily in the nasopharynx. Extra-nasopharyngeal angiofibromas are rarer. Remarkably, only a case of external auditory canal location has been reported.

Bilateral orbito-cerebral-extending frontal mucocele following nasosinus polyposis: A case report.

Introduction: and importance: Mucoceles are expansive pseudocystic formations, developed from the sinuses of the face, affecting mainly adults. Evolving at low noise, they are most often revealed by neurological or ophthalmological complications. We report a rare case of a bilateral frontal mucocele with orbito-cerebral extension following nasal sinus polyposis.
