1/5. Ophthalmic manifestations of esthesioneuroblastoma.Esthesioneuroblastoma, a tumor that arises from the olfactory sensory epithelium, often manifests with ocular and orbital signs and symptoms. A review of 38 cases of esthesioneuroblastoma at the Mayo Clinic revealed that ophthalmic signs or symptoms occurred in 28. Twenty patients had ophthalmic signs or symptoms at the time of presentation, and five of these had ocular symptoms as the primary complaint. Five patients presented to an ophthalmologist, but a nasal or paranasal sinus tumor was not suspected. Periorbital pain and excessive tearing were the most commonly reported symptoms. The most common ophthalmic sign was eyelid edema followed by proptosis, globe injection, and ptosis. Recognition of the signs and symptoms of neoplasms of the nose and paranasal sinuses and consideration of esthesioneuroblastoma in the differential diagnosis by clinicians and pathologists allow for prompt management of this tumor.- - - - - - - - - - ranking = 1keywords = paranasal sinus, paranasal, sinus (Clic here for more details about this article) |
2/5. osteoma: an unusual cause of amaurosis fugax.A 16-year-old white boy presented with a history of amaurosis fugax associated with an afferent pupillary defect, proptosis, discomfort of the left eye. Tomograms of the skull and of the orbit revealed a lobulated 4-cm ivory osteoma arising from the left ethmoid sinus and extending into the maxillary sinus and left orbit. After surgical extirpation, visual acuity returned to normal and the papilledema resolved after 4 months. This patient is 1 of 37 patients with osteoma of the paranasal sinuses or of the orbit (or of both) who underwent surgical treatment at the Mayo Clinic between the years 1948 and 1977. Twelve of these patients had orbital involvement, and only these patients had ocular signs and symptoms.- - - - - - - - - - ranking = 0.52695947781287keywords = paranasal sinus, paranasal, sinus (Clic here for more details about this article) |
3/5. carotid-cavernous sinus fistula caused by rupture of a primitive trigeminal artery aneurysm. Case report.A case is reported in which an aneurysm arising at the junction of the right internal carotid artery and a persistent primitive trigeminal artery ruptured to form a carotid-cavernous fistula. The internal carotid artery was ligated without any signs of brain-stem ischemia due to inverted blood flow through the primitive trigeminal artery.- - - - - - - - - - ranking = 0.053918955625747keywords = sinus (Clic here for more details about this article) |
4/5. Traumatic carotid-cavernous sinus fistula.Seventy-five percent of carotid-cavernous sinus fistulae result from high velocity head trauma. The most common symptom is a pulse synchronous bruit which usually becomes apparent when the patient regains his sensorium. The objective manifestations of such an arteriovenous fistula are characteristically localized to the ipsilateral orbit. A periorbital bruit and venous engorgement of the palpebral and bulbar conjunctivae are pathognomonic features. Bilateral carotid angiography confirms the diagnosis and determines which of several techniques might be used to obliterate the fistula. Occasionally the classic signs and symptoms may be delayed for days or weeks. Thus, the maxillofacial surgeon must be aware of this clinical entity to avoid untimely repair of facial fractures with potentially disastrous consequences.- - - - - - - - - - ranking = 0.067398694532184keywords = sinus (Clic here for more details about this article) |
5/5. Aseptic cavernous sinus thrombosis after internal carotid arterial occlusion in polycythaemia vera.Two patients with untreated polycythaemia vera developed intracranial internal carotid arterial occlusion followed by monocular blindness and the characteristic features of ipsilateral cavernous sinus thrombosis. Primary septic source and signs of systemic infection were absent. It is suggested that the predisposing factors in this unusual syndrome were hyperviscosity and venous sludging induced by the basic haematological disorder and progression of the thrombotic process within the internal carotid artery towards its intracavernous portion with occlusion of the ophthalmic artery and of the arterial branches which supply the walls of the sinus.- - - - - - - - - - ranking = 0.08087843343862keywords = sinus (Clic here for more details about this article) |
