introduction: osteoma is a benign tumor rarely found in the paranasal sinuses.   case report: a 30-year-old female presented with an 8-month history of proptosis of the right eye that was progressing slowly. she was diagnosed with ethmoid osteoma and managed with collaborative surgery at the ophthalmology and otolaryngology departments. after surgery, the patient suffered visual loss that was m...

Tissue samples from four progressive ethmoid hematomas were positive for expression of vascular endothelial growth factor (VEGF), also known as vascular permeability factor. VEGF is known to have an important role in tumor biology, including but not limited to angiogenesis, malignant ascites, and the proliferative retinopathies. Further study of its activity in ethmoid hematoma could provide ne...

Mucoceles are defined as chronic, cystic lesions in the paranasal sinuses. When the mucocele content becomes infected, the lesion is defined as mucopyocele. Most mucoceles are located in the frontal and anterior ethmoid sinuses and normally they involve the frontal-ethmoid complex, expanding to the superior-medial region of the orbit, leading to ocular disorders; maxillary sinus presentation is...

Ethmoid polyposis are the nasal polyps which developed from ethmoidal sinuses located between nose and eyes. Usually it is allergic in nature can be multiple, grape like masses. The estimated ethmoid prevalence India 4%. In this case study, a 61 year old female patient was admitted with complaints of severe block since approximately 6 months.

BACKGROUND Aneurysmal bone cyst is an expansile bone lesion, non-neoplastic in nature, occurring most commonly in long bones. It is uncommon in facial bones and exceptionally rare in ethmoid bone. Ten cases of aneurysmal bone cysts of ethmoid bone have been reported so far. CASE REPORT A young adolescent presented with decreased vision and pain in the right eye. MRI revealed an expansile lesi...

Cemento-ossifying fibroma is a benign fibroosseous lesion that contains fibrous tissue and calcified tissue resembling bone, cementum or both. It is frequently seen in the mandibula and maxilla, but it may rarely affect the ethmoid sinus. In this report, we presented computed tomography findings of an ossifying fibroma of the ethmoid sinus associated with exophthalmos. A 25-year-old woman prese...

We report a case of intraparenchymal pneumocephalus caused by ethmoid sinus osteoma in a 57-year-old man who had suffered from severe allergic rhinitis because of which he had to frequently blow his nose. He was referred to our hospital for headache and mild left hemiparesis. A computed tomography scan revealed a large intraparenchymal air entrapment in the right frontal lobe related to an oste...

Nasopharyngeal carcinoma (NPC) may spread to the paranasal sinuses. This retrospective study describes the features of paranasal sinus involvement in NPC on computed tomography (CT) and magnetic resonance imaging (MRI). One hundred and fourteen patients with histologically proven NPC underwent staging with both CT and MRI. Maxillary sinus infiltration was demonstrated on MRI in 10 patients; sph...
