Inflammatory pseudotumor is an unusual benign but potentially invasive lesion. In the head and neck area, it mainly involves the orbit and paranasal sinuses. We present a case in tonsil and neck. After tonsillectomy and steroid therapy, there has been no recurrence.

A case of primary Ewing's sarcoma of the orbit and paranasal sinuses in a 6-yearold boy is reported. The child presented with headaches and unilateral visual loss. Loss of vision as a result of optic nerve involvement with primary Ewing's sarcoma is extremely rare.

Objective-  to provide a reference anatomy of the paranasal sinuses of the goat by using computed tomographic modality. Design- Experimented study.   Animals- Five male Rayini goats.   Procedures- CT images were acquired from the head region perpendicular to the hard palate. CT windows were adjusted as necessary to  obtain the optimal image for the paranasal sinuses. The images were studie...

OBJECTIVES/HYPOTHESIS To describe surgical outcomes and radiographic features of olfactory groove meningiomas treated by excision through the subcranial approach. Special emphasis is placed on paranasal sinus and orbit involvement. STUDY DESIGN Retrospective review of a series of patients. METHODS Nineteen patients underwent excision of olfactory groove meningioma (OGM) via the transglabell...

The paranasal sinus system of horses is complex, comprising six pairs of sinuses. Disease processes that can develop in the sinuses include ethmoid hematomas, cysts, neoplasia, and bacterial and fungal infections. Horses that develop paranasal sinus disease vary widely in age. A significant number of clinical conditions involving the paranasal sinuses require a combination of diagnostic tests t...

Osteoma is a benign, slowly growing tumor that mainly occurs in the bones and cavities of the middle third of the face, representing the most frequent benign tumor of the paranasal sinuses. It rarely originates primarily from the orbit. Most of these lesions develop in the fourth to fifth decades of life, and are more commonly encountered in males. In the English literature, there are so far th...

Mucormycosis is an acute, often fatal intection caused by saprophytic fungi, of the order Mucorales. It occurs in debilitated patients who are compromised immunologically due to uncontrolled diabetes lymphoma, corticosteroid treatment and radiotherapy (Jain et al., 1978). Only 13 cases were reported up to 1963 (Pilsbury and Fischer, 1977). The fungus appears in tissues as hyphae which are irreg...

OBJECTIVE To review the entity of respiratory epithelial adenomatoid hamartoma of the paranasal sinuses using an illustrative case example of frontal sinus hamartoma. METHODS Case report with review of the literature. RESULTS Respiratory epithelial adenomatoid hamartoma represents a benign process that is generally cured with conservative surgical resection of the involved area. Nevertheles...

Neuroendocrine neoplasms are defined as epithelial neoplasms with predominant neuroendocrine differentiation. They can arise in almost every organ of the body although they are most commonly found in the gastrointestinal tract and respiratory system. Nasal cavity and paranasal sinuses are a rare site for neuroendocrine carcinoma. In contrast to the other regions, neuroendocrine tumours of the s...
