Serious infection in the paranasal sinuses may present with symptoms suggestive of neurological disease and thus lead to delay in the diagnosis and subsequent treatment. We present three such cases inwhom the initial diagnoses had been acute optic neuritis, a posterior communicating aneurysm and an intracranial space occupying lesion. The fourth patient had meningitis but the paranasal sinuses ...

Lymphoma is usually the malignant tumor which originates from lymph node or lymph-tissues. The nasal cavity and paranasal sinuses are rare primary sites for lymphoma. In the paranasal sinuses, lymphoma of maxillary sinuses is the most common, ethmoidal sinuses is more than that of frontal sinuses, sphenoid sinuses is the least. The most common presenting symptoms are nasal obstruction, rhinorrh...

Chordomas are malignant, nonepithelial neoplasms derived from notochordal tissue. A primary chordoma of the nasal cavities and paranasal sinuses is extremely rare compared with clival chordomas, which often present as nasal masses after spreading anteriorly. Only a few cases of primary chordoma of the nasal cavities and paranasal sinuses have been reported in the literature. We report a case of...

aggressive malignancy arising from the nasal cavity and paranasal sinuses. Sinonasal undifferentiated carcinoma was first reported in 1986 by Frierson et al, and since then less than 100 cases have been reported in the literature.1 One previous pediatric case has been described in a 12-year-old boy in India.2 Sinonasal undifferentiated carcinoma is histologically classified as part of a spectru...

Our nose, paranasal sinuses, as well as the throat (pharynx) are part of the upper respiratory tract, which consists of two parts. Anatomically, the external and internal parts of the nose can be illustrated. The first consists of nasal bones and nasal cartilages and the internal nose is formed by the nasal cavity and the nasal concha also known as turbinates (choanae), are separated by the nas...

Sarcomatoid carcinoma of nasal cavity and paranasal sinuses is an extremely rare malignant neoplasm. We report a case of sarcomatoid carcinoma arising in the left-side nasal cavity and paranasal sinuses in a 65-year-old man who was hospitalized for left-side nasal epistaxis, odor sensation. Histopathologic examination revealed the tumor was composed of pleomorphic spindle and round cells with f...

BACKGROUND Endoscopic transnasal approaches to the orbit have been recently described and they have been proposed as an option in the surgical management of medial and inferior orbital lesions. METHODS Retrospective evaluation of 3 patients operated on in our department during 2011 to remove a cavernous hemangioma of the inferior-medial orbit. Two patients were operated on via an endoscopic t...
