Purpose. To present a unique case of Non-Hodgkin's-Lymphoma- (NHL) associated compressive optic neuropathy. Method. An 89-year-old male presenting with acute unilateral visual loss and headache. Results. Patient was initially diagnosed with occult giant cell arteritis; however after visual acuity deteriorated despite normal inflammatory markers, an urgent MRI scan revealed an extensive paranasa...

Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive version of squamous cell carcinoma (SCC) that preferentially occurs in the upper aerodigestive tract. Since the first description by Wain SL et al., in 1986, only 21 cases with BSCC in the nasal cavity or in the paranasal cavity have been reported in the English literature. We present a case of BSCC arising in a paranasal sinus, a...

Endoscopic sinus surgery is a standard procedure in the treatment of various pathologies such as chronic sinusitis or some types of neoplasms. The transnasal approach to tumours of paranasal sinuses is favourable due to functional and aesthetic reasons. We report a rare case of a large primary ectopic meningioma of the paranasal sinuses in a 48-year-old woman referred to the Otolaryngology Clin...

Osteoma is the most common benign tumour of the nose and paranasal sinuses. However, involvement of the sphenoid sinus by osteoma is rare. Most of the time, patients with paranasal sinus osteoma are asymptomatic. However, symptoms may present, depending on the location and extension of the tumour. We report a case of a patient with sphenoethmoidal osteoma found incidentally on imaging, with evi...

Actinomycosis is a chronic suppurating granulomatous disorder specific to soft tissue. It is produced by Actinomyces Israelii, gram positive anaerobic bacteria that are very difficult to culture, and a commensal saprophyte of the oral cavity (tonsillar crypts, saliva and gingival dental sulci) and the gastro-intestinal tract; it becomes a pathogen in the face of erosions of the oropharyngeal mu...

Paranasal sinuses are paired cavities within the skull, which develop by evagination into spongy bone between external and internal plates of cranial facial bones. Thus, each sinus is lined respiratory epithelium has direct or indirect communication to nasal cavity. The purpose this chapter present an anatomical reference guide paranasal in domestic animals, including large small ruminants (cat...

Inflammation of the equine paranasal sinuses is a relatively uncommon disease that may be caused by primary bacterial or mycotic infections (Mason 1975a), or can be secondary to dental disease (van der Velden & Verzijlenberg 1984, Scott 1987, Tremaine & Dixon 2001a), facial trauma, sinus cysts, progressive ethmoid hematoma or sinonasal neoplasia (Mansmann & Wheat 1973, Gibbs & Lane 1987, Tremai...

We report a young woman presenting with digital gangrene, paranasal sinusitis, mononeuritis multiplex, and rapidly progressive glomerulonephritis without asthma and eosinophilia - an extremely rare variant of this disease.
