Sinonasal undifferentiated carcinoma (SNUC) is an aggressive malignancy originating in the mucosa lining the walls of the nasal cavity and paranasal sinuses. It is a rare tumor that usually presents in an advanced stage, is highly invasive, and is traditionally reputed to be refractory to even the most radical therapy with an attendant poor prognosis. This is particularly true when it transgresses the cranial base.
Abstract:In small childrens spine injuries are rare. In this age group upper cervical spine is commonally affected. Odontoid process fracture involve only a subset of cervical spine fractures. In small childrens, this fracture typically involves the cartilaginousplate that separates the odontoid process from the body of the axis. Odontoid processfracture is rare in children less than 7 years of age.
Abstract:Lumbar disc herniation is a common disease that present with back pain and radicular pain. The most efficient method for the treatment of lumbar disc herniation is still controversial. Spontaneous regression of lumbar disc herniation has been recognized with the advancement of radiological diagnostic tools and can explain the reason of spontaneous relief of symptoms without treatment. The proposed hypothesis are; dehydration, retraction of the disc herniation in the annulus fibrosus, enzymatic catabolism and phagocytosis. In this study we present a case with large lumbar disc herniation regressing by itself and the potential mechanisms of disc regression have been discussed.
Ventriculoperitoneal (VP) shunt, a common neurosurgical procedure, has a long list of known complications associated with it. A rare but dangerous complication of VP shunt procedure is extradural hematoma (EDH). It can be diagnosed and managed easily before it turns into a catastrophic complication.
Background: Juvenile angiofibroma is an uncommon, benign and extremely vascular tumor that presents as recurrent severe epistaxis with or without nasal obstruction in adolescent males. It is believed to arise from the posterolateral wall of the nasal cavity at the level of the sphenopalatine foramen. This typically produces characteristic radiological appearance that often renders biopsy unnecessary. However absence of classical radiological features can lead to misdiagnosis and inadvertent life threatening intraoperative complications. Purpose: To highlight the importance of absence of classical radiological presentation of Juvenile nasopharyngeal angiofibroma and add to the curreent knowledge of diagnosis and management of this crucial disease. Result: We came across 15 unique cases of nasopharyngeal angiofibroma with atypical radiological appearance amongst 34 cases over a period of 4 years. All of these cases had absence of nearly all the classical radiological findings. Only one such case was found reported on searching the available English literature on pubmed. Conclusion: With strong clinical suspicion even in the absence of classical radiological signs a differential diagnosis of JNA should be considered when diagnosing any nasal or nasopharyngeal mass owing to the risk of associated life threatening hemorrhage. Furthermore, the absence of classical radiological signs emphasize the need for further research on the site of origin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
