1/58. mucocele of the anterior clinoid process: case report.OBJECTIVE AND IMPORTANCE: Of the primary intracranial mucoceles, those arising from the optic canal or anterior clinoid process are extremely rare. To our knowledge, only five cases have been reported. The pathogenesis of mucoceles at this unusual site is unclear, but the previously reported cases suggest that these mucoceles may originate from pneumatizing air cells in the anterior clinoid processes. CLINICAL PRESENTATION: A 43-year-old woman presented with diplopia. magnetic resonance imaging showed a small mass, compressing the optic nerve, in the medial portion of the left anterior clinoid process. The medial portion of the anterior clinoid process surrounding the mass was eroded and the bony margins of the mass were well corticated in computed tomographic scans. There was no direct connection between any paranasal sinus and the mass cavity, as assessed in imaging studies and intraoperatively confirmed. The pathological diagnosis after the operation indicated a mucocele. CONCLUSION: Considering the absence of air cells in the anterior clinoid processes, the mucocele in this case might have originated from ectopic mucinous tissue that appeared during the development of the optic canal, rather than from a pneumatizing air cell.- - - - - - - - - - ranking = 1keywords = paranasal sinus, paranasal, sinus (Clic here for more details about this article) |
2/58. Disseminated hydatid disease causing paraplegia and destruction of the hip.A patient who had had been treated by surgery for spinal echinococcosis in a Mediterranean country emigrated to northern europe. After surgery, the echinococcosis disseminated and he developed chronic lytic and sinus-draining hydatid disease of the left hip and neuromuscular weakness of the left lower extremity. Seventeen years after the spinal surgery, he was referred to our hip service for a possible total hip replacement (THR) after receiving adequate chemotherapy against echinococcosis for nearly 3 years. Because of the poor results reported by others, we decided against THR; two of the four previous patients described in the current literature who had THR died due to complications.- - - - - - - - - - ranking = 0.060667825997781keywords = sinus (Clic here for more details about this article) |

4/58. Pneumosinus dilatans multiplex, mental retardation, and facial deformity.Pneumosinus dilatans is a term used to describe enlargement of one or more paranasal sinuses without radiological evidence of localized bone destruction, hyperostosis, or mucous-membrane thickening. To date, many cases have been reported that involved frontal, ethmoid, sphenoid, and maxillary sinus. However, no case has been reported that involved all paranasal sinuses. Our case involved mastoid air cells as well as all paranasal sinuses. It is named pneumosinus dilatans multiplex by us. This is the first case to be reported in English literature that has this syndromic condition of pneumosinus dilatans multiplex, mental retardation, and facial deformity.- - - - - - - - - - ranking = 3.4853426079823keywords = paranasal sinus, paranasal, sinus (Clic here for more details about this article) |
5/58. Lethal rhinocerebral phycomycosis in a healthy adult: a case report and review of the literature.A lethal case of rhino-orbital-cerebral phycomycosis (mucormycosis) in an otherwise healthy man is presented. The clinical, radiologic, and ante mortem surgical pathology associated with microbiologic examinations failed to yield the diagnosis of fungal infection as the cause of a clinical presentation of acute sphenoid sinusitis with a fulminant cavernous sinus thrombosis. No similar case report was found in review of the literature. There is a need for a high degree of suspicion in this condition to improve the uniformly poor prognosis in this devastating infectious disease. Emphasis is placed on the necessity for early tissue or microbiologic diagnosis with appropriate histologic stains and fungal cultures. Treatment consists of extensive surgical excision of all necrotic or questionably viable tissue in conjunction with alternate-day amphotericin b therapy.- - - - - - - - - - ranking = 0.12133565199556keywords = sinus (Clic here for more details about this article) |
6/58. A case report of inflammatory pseudotumor involving the clivus: CT and MR findings.The authors describe a rare case of inflammatory pseudotumor involving the clivus, where a soft tissue mass lesion, with extension into the prevertebral retropharyngeal space and the cavernous sinuses, was detected by CT and MRI. The mass resembled a malignant tumor or aggressive infectious lesion, and the final diagnosis of inflammatory pseudotumor was a diagnosis of exclusion, decided after histopathological examination.- - - - - - - - - - ranking = 0.060667825997781keywords = sinus (Clic here for more details about this article) |
7/58. An algorithm for management of residual posttraumatic calvarial defects in adults.For the discussion of options in late reconstruction of residual posttraumatic calvarial defects in adults, the calvaria is divided into three reconstructive zones. Zone 1 comprises the frontal sinus region and the contour of the supraorbital brow; Zone 2 comprises the smooth, cosmetically visible prehairline forehead; Zone 3 comprises the posthairline area and the calvaria. The particular reconstructive requirements (autogenous bone versus alloplastic material) of each zone are described and illustrated with clinical cases. The merits of bone from various donor sites and those of alloplastic material are discussed. The authors present an algorithm of reconstructive choices for residual posttraumatic calvarial defects in adults based on the nature of the defect and the aesthetic reconstructive zone.- - - - - - - - - - ranking = 0.060667825997781keywords = sinus (Clic here for more details about this article) |
8/58. Cranial and orbital epidermoid tumours.This paper reports on 14 cases of cranial and orbital epidermoid tumours, of which 2 epicranial, 4 extradural intracranial, 4 fronto-orbital-sinusal, 2 orbital and 2 orbito-nasal cases. Referring to these cases and data published in the specialised literature, the authors show that this type of tumour is more frequent in males, and is generally of embryologic but very rarely of mechanical origin. The main symptom is tumefaction in cranial tumours and exophthalmos in orbital tumours. There is very rarely association with a space-occupying process (tumour, cerebral abscess). Evolution is slow and progressive; the only treatment is surgical. After total ablation there were no recurrences and the postoperative course was very satisfactory.- - - - - - - - - - ranking = 0.060667825997781keywords = sinus (Clic here for more details about this article) |
9/58. Giant cell reparative granuloma of the occipital bone.Giant cell reparative granuloma (GCRG) is a non-neoplastic fibrous lesion with unevenly distributed multinucleated giant cells, areas of osseous metaplasia and hemorrhage. The small bones of the hands and feet are the most common sites, followed by the vertebral bodies and craniofacial bones. In the craniofacial bones GCRG has been reported in the temporal bone, in the frontal bone and paranasal sinus. However, to the best of our knowledge no case has been reported in the occipital bone. We report on the imaging findings and pathological features of a GCRG of the occipital bone and discuss the differential diagnosis of this entity in this particular location, especially with giant cell tumor because of the therapeutic and prognostic implications.- - - - - - - - - - ranking = 1keywords = paranasal sinus, paranasal, sinus (Clic here for more details about this article) |
