Neurofibromas of the paranasal sinuses
The Journal of Laryngology & Otology, 1988Two cases of neurofibroma of the paranasal sinuses are presented. The tumours presented as space-occupying lesions and were treated by local excision. Histologically one was a typical neurofibroma, whilst the other showed some features of a schwannoma. The patients show no evidence of tumour recurrence at 18 and 6 months respectively.

Aspergillosis of the Paranasal Sinuses
Archives of Otolaryngology - Head and Neck Surgery, 1975Aspergillosis of the paranasal sinuses may occur as a chronic disease in an otherwise healthy person. This infection is usually confined to a single paranasal sinus, the maxillary antrum, though it can involve the orbit and may initiate with findings of proptosis and decreased vision.

Meningioma of the paranasal sinuses [PDF]
Neuroradiology, 1979 Meningiomas originating in the paranasal sinuses are rare. These tumors are thought to arise from embryonal arachnoid nests which were pinched off and left behind during embryonic development. We have described various radiographic findings of two patients with meningioma arising in the paranasal sinuses (frontal sinus origin in a 65-year-old female ...

Aspergillosis of the paranasal sinuses
Neuroradiology, 1992The CT appearances of 13 cases of pathologically proven aspergillosis involving paranasal sinuses were reviewed. Symptoms included rhinorrhea, nasal obstruction, headache, facial pain and foul smell from the nose. At operation, these lesions appeared yellowish, brownish, grey or black in colour, and contained dirty or muddy material.

Myxoma of the paranasal sinuses
The Journal of Laryngology & Otology, 1994AbstractMyxomas of the paranasal sinuses are rare but well described in the literature. They may be related to dental malformations or missing teeth, but may also occur without any such abnormalities. Their local aggressiveness and ability to erode bone should not be underestimated, and they should be totally removed whenever possible. A case of myxoma

Leiomyoma of the paranasal sinuses
The Journal of Laryngology & Otology, 1993AbstarctThe paranasal sinuses are a rare site for tumours of myogenic origin. There has been only one previously reported case in the English literature. We present a case of a leiomyoma filling the anterior ethmoid sinus and middle meatus which was excised via a Patterson's external ethmoidectomy.

While the gas-filled cavities of the face, the paranasal sinuses, are one of the most complex bony areas of the body, their exact function remains unknown. Many pathologic conditions affect the sinuses and imaging is central to their diagnosis. Plain radiographs (Caldwell, Waters, lateral and submentovertex projections performed with a horizontal beam ...

Tumors of the Paranasal Sinuses
Otolaryngologic Clinics of North America, 1988Benign and malignant tumors, including polyps, represent conditions that occur frequently enough to be considered in the differential diagnosis of sinus disease. The locations and extent of these lesions (especially malignant tumors) should be evaluated by CT and MRI.

Imaging of the Paranasal Sinuses
Oral and Maxillofacial Surgery Clinics of North America, 2012Evaluation of the paranasal sinuses is often performed in a purely clinical fashion, without the need for imaging. However, in certain instances imaging may be deemed valuable or even necessary in helping to solve a diagnostic dilemma, confirm a suspected diagnosis, evaluate the extent of a known condition, or assess for an underlying cause of the ...
