چکیده
The osteomas are osseous lesions with slow and asymptomatic growth that mostof the times isafinding inradiologicalexamsrequested forother reason. It’s the most common benign neoplasm of the paranasal sinuses. The osteomas are located mainly in the frontal sinus (37–80%), followed by the ethmoidal sinuses (20%),maxillarysinusesandrarely in thesphenoidsinus. Although osteoid osteoma is rare in paranasal sinuses, it should be considered if there is a bone density mass and complete excision should be performed with care. Although osteomas are benign tumours, they may enlarge progressively and produce complications. Their resection is not free of risks, so there is some controversy about the management of asymptomatic patients. Endonasal surgery reduces the morbidity of the treatment but the location and size of the lesions do not allow to employ this technique in all cases.

We are reporting a case of pancreatic heterotopia presenting as a lead point of ileo-ileal intussusception in a 1year 3month year...
متن کاملThe possible viral aetiology of disseminated sclerosis.
The two most attractive current hypotheses concerning the aetiology of disseminated (multiple) sclerosis (MS) are those of (1) an 'autoimmune' process, analogous to experimental allergic encephalitis, or (2) an infection, for which the 'slow virus diseases' of the central nervous system represent a possible model. Experimental data have been advanced favouring each hypothesis, and it is in fact...
متن کاملInflammatory Septal Nasal Polyp
Introduction: Nasal polyps are benign prolapsed mucosal lesions which commonly arise from the paranasal sinuses and lateral walls of the nose especially the contact areas of osteomeatal complex. Though nasal polyps arising from the nasal septum have been reported, those arising from its anterior part are extremely rare and present a diagnostic dilemma.
