A 49-year-old male was brought to the Emergency Department after being found unresponsive. The patient had multiple seizures and was intubated in the prehospital setting. A computed tomography scan showed bilateral paranasal sinus disease, and magnetic resonance imaging showed a right frontal abscess and subdural empyema. Neurosurgery took the patient to the operating room, performed a craniotomy, and drained a large amount of purulent fluid. He was subsequently discharged for acute rehabilitation. Clinicians should consider complicated frontal sinusitis, especially in the undifferentiated patient presenting with neurologic deficits and signs or symptoms of sinus disease...

Central nervous system aspergillosis is rare with reported mortality rate of 13-50% involving foci in paranasal sinuses and even higher mortality rates (80-100%) in patients of immune-compromised status. Modern day imaging offers an opportunity for early diagnosis, but findings are minimal. A typical finding is that of a space occupying mass lesion with iso-hypointense signal on T1-weighted sequences and extreme hypointense appearance on T2-weighted. This results from the concentration of ferromagnetic substances (iron/zinc/magnesium/manganese) within the lesion...

Generally, meningioma is considered intracranial lesion occurring in the intradural compartment. However, meningioma can also occur and usually confined in the extradural compartment called as primary extradural meningioma (PEM). PEM represents a special subgroup of meningioma constitute about 1% of all meningioma. PEM arises outside the subdural compartment and usually contains neither connection underlying subdural structures nor extends into with subdural compartment. It is commonly located in the paranasal sinus, middle ear, rarely in the intradiploic spaces of calvarial bone such as temporal, frontal, and parietal bone and orbit but extremely uncommonly in the occipital and sphenoid bones...

BACKGROUND: Paranasal sinus osteoma is a common, asymptomatic, histologically benign, and slow-growing tumor. However, it can give rise to secondary pathologies such as a mucocele in about 50% of the cases. Rarely, intracranial and orbital extension is present leading to rhinoliquorrhea, pneumocephalus, or neurological and visual impairment, which might be potentially life-threatening. CASE DESCRIPTION: A 49-year old man presented with an acute frontal lobe syndrome and rhinoliquorrhea...

BACKGROUND: and Importance: Sinusitis is a common clinical condition but sphenoid sinusitis is a less common form and even rarer is hypophysitis as a complication of the latter. Clinically, hypophysitis may mimic a pituitary neoplasm in presenting with mass effect and pituitary hormone dysfunction. CLINICAL PRESENTATION: We present five cases of sinusitis-related hypophysitis treated at the Royal Care International Hospital in Khartoum, Sudan. Clinical symptoms at presentation included: headache, fever, ptosis, ophthalmoplegia and history of sinusitis with running nose (nasal discharge)...

The clinical distinction of chronic respiratory rhinitis appears to confirm the evo-devo theory of the three noses. The authors report two cases of advanced allergic rhinitis, in which chronic inflammation had induced a violaceous colour of the mucosa of the respiratory nose and a whitish polypoid appearance of the free edge of the middle turbinate. Nose and paranasal sinus CT scan revealed, beyond the virtual nasal cavities observed on nasal endoscopy and CT imaging, normal radiolucency or only minor opacities of the ethmoid (i...

INTRODUCTION: Allergic rhinitis is a prevalent condition warranting special aeromedical consideration due to its potential for acute and painful manifestations involving the middle ear or paranasal sinuses during rapid barometric pressure changes. Although second generation antihistamines and intranasal steroids are safe and effective treatments for this common condition, aeromedical management varies. METHODS: An aeromedical policy review of 14 public access civil and military data repositories was undertaken...

The concept of chronic rhinosinusitis with or without polyps is founded on the structural and functional unicity of the pituitary mucosa and its united response to environmental aggression by allergens, viruses, bacteria, pollution, etc. The present review sets this concept against the evo-devo three-nose theory, in which nasal polyposis is distinguished as specific to the olfactory nose and in particular to the non-olfactory mucosa of the ethmoid, which is considered to be not a sinus but rather the skull-base bone harboring the olfactory mucosa...

A 44-year-old male with schizophrenia presented with progressive right proptosis for one year and conjunctivitis for two months. An orbital cyst was seen in the superotemporal region on computerized tomography and was surgically removed. There was no history or radiological signs of paranasal sinus disease or previous trauma. Histopathologic evaluation revealed a cyst lined with respiratory epithelium. Respiratory choristomatous cysts of the orbit are considered rare in both pediatric and adult patients. We review the literature of respiratory orbital cysts and conclude that they tend to present in adults and should be considered in the differential diagnoses of orbital cysts...

BACKGROUND: With the exception of osteomas, bone neoplasms that originate in the sinonasal cavity are seldom diagnosed on preoperative imaging due to a lack of characteristic radiographic features. Here we described the unusual occurrence of an osteoblastoma in the paranasal sinuses, and we drew focus to its salient imaging features. A highly unique imaging sign was indicated, and its pathologic basis was explained, with concurrent review of the literature. METHODS: Case series and review of the literature...

Objectives The diagnosis of chronic rhinosinusitis without nasal polyps (CRSsNP) and distinguishing it from allergic rhinitis is difficult. Yet, early detection of CRSsNP is important to prevent progressive and severe chronic rhinosinusitis. Our aim was to compare diagnostic accuracy of symptoms, endoscopy, and imaging signs of CRSsNP and allergic rhinitis -only phenotypes. Setting Prospective controlled follow-up study. Participants Forty-two nonsmoking patients visiting tertiary care due to CRSsNP and 19 nonsmoking volunteer controls with allergic rhinitis filled a symptoms questionnaire and underwent nasal endoscopy off-seasonally...
